Translating by qhwdw The Best Linux Laptop (2017-2018): A Buyer’s Guide with Picks from an RHCE

|

If you don't posses the right knowledge & the experience, then finding the best Linux laptop can be a daunting task. And thus you can easily end-up with something that looks great, features great performance, but struggles to cope with 'Linux', shame! So, as a **RedHat Certified Engineer** , the author & the webmaster of this blog, and as a **' Linux' user with 14+ years of experience**, I used all my knowledge to recommend to you a couple of laptops that I personally guarantee will let you run 'Linux' with ease. After 20+ hours of research (carefully looking through the hardware details & reading user feedback) I chose [Dell XP S9360-3591-SLV][2], at the top of the line. If you want a laptop that's equipped with modern features & excellent performance **that 'just works' with Linux**, then this is your best pick.
|
||||
|
||||
It's well built (aluminium chassis), lightweight (2.7 lb), features powerful hardware, long battery life, includes an excellent 13.3 inch Gorilla Glass touchscreen with 3200×1800 QHD resolution which should give you excellently sharp images without making anything too small & difficult to read, a good & roomy track-pad (earlier versions had a few issues with it, but now they seem to be gone) with rubber-like palm rest area and a good keyboard (the key travel is not deep, but it's a very think laptop so…) with Backlit, two USB 3.0 ports. Most importantly, two of the most common elements of a laptop that can give 'Linux' user a headache, the wireless adapter & the GPU (yes the Intel HD Graphics 620 **can play 4K videos at 60fps** ), they are both **super compatible with 'Linux'** on this Dell.
|
||||

|
||||
|
||||
One drawback is that it doesn't have an HDMI port. In its place, Dell has added a Thunderbolt 3 port. So your only option is to use a Thunderbolt to HDMI converter (they're pretty cheap). Secondly, you can't upgrade the 8GB of RAM after purchasing (you can change the hardware configuration -- CPU, RAM & SSD, before purchasing), but in my opinion, 8GB is more than enough to run any 'Linux' distribution for doing everyday tasks with ease. I for one have an Asus laptop (received it as a gift) with a 5th generation of Core i7, 4GB of RAM, I use it as my main computer. With Chrome having opened 15-20 tabs, VLC running in the background, file manager & a code editor opened, it handles it with ease. If I cut back some of the browser tabs (say reduce them to to 4-5), then with the rest of the apps opened, I can even work with a virtual machine on Virtualbox. That's with having 4GB of RAM, so with 8GB of RAM and other more powerful hardware, you should be absolutely fine.
|
||||
|
||||
> **Note:** I 've chosen a solid set of [hardware for you][2], but if you want, you can further customize it. However, don't choose the '8GB RAM/128GB SSD' option. Because that version gives you the 1920×1080 FHD screen, and that resolution on a 13.3″ screen can make things like menus to appear a bit smaller, slightly difficult to read.
|
||||
|
||||
### **Best Cheap Linux Laptop**
|
||||
|
||||
![][5]
|
||||
|
||||
If the Dell is a bit pricey and you want something that is affordable, but still gives you surprisingly similar performance & really good compatibility on 'Linux, then your 2nd best option is to go for the [Acer Aspire E 15 E5-575G-57D4][6]. Its 15.6″ display is certainly not as good as the one Dell gives you, but the 1920×1080 Full HD resolution should still fits nicely with the 15.6″ screen making things sharp & clear. The rest of the hardware is actually very similar to the ones the more pricier Dell gives you, but **at 5.2 lb it 's a little heavy.**
|
||||
|
||||
You can actually customize it a lot. The basic setup includes a 7th generation Core i5 CPU, 15.6 inch FullHD (1920 x 1080) screen, 8GB of DDR4 RAM, 256GB SSD drive, Intel HD Graphics 620 GPU and also a separate (discreet) Nvidia 940 MX GPU, for ports: HDMI 2 USB 3.0, 1 x USB 2.0 & 1 USB 3.1. For $549, it also **includes a DVD burner** … [**it 's a bargain**][6].
|
||||
|
||||
As far as the 'Linux' compatibility goes, it's really good. It may not be top notched as the Dell XPS, yet, as far as I can see, if there is one thing that can give you troubles it's that Nvidia GPU. Except for one user, all the others who have given feedback on its 'Linux' compatibility say it runs very smoothly. Only one user has complained that he came up with a minor issue after installing the proprietary Nvidia driver in Linux Mint, but he says it's certainly not a deal breaker. This feedback is also in accordance with my experience with a mobile Nvidia GPU as well.
|
||||
|
||||
For instance, nowadays I use an Asus laptop and apart from the integrated Intel GPU, it also comes with a discreet Nvidia 920M GPU. I've been using it for about an year and a half. [I've run couple of 'Linux' distributions on it][7], and the only major issue I've had so far was that after installing the proprietary driver [on Ubuntu 17.10][8] and activating Nvidia as the default GPU the auto-user-login function stopped working. And every time I had to enter my login details at the login screen for entering into the desktop. It's nowhere near being a major issue, and I'm sure it could've been fixed by editing some configuration settings of the login-manager, but I didn't even care because I rarely use the Nvidia GPU. Therefore, I simply changed the GPU back to Intel and all was back to normal. Also, a while ago I [enabled 'Motion Interpolation' on the same Nvidia GPU][9] on [Ubuntu 16.04 LTS][10] and everything worked like a charm!
|
||||
|
||||
What I'm trying to say is that GPU drivers such as those from Nvidia & AMD/ATI used give users a real hard time in the past in 'Linux', but nowadays things have progressed a lot, or so it seems. Unless you have at your disposal a very recently released high-end GPU, chances are 'Linux' is going to work without lots of major issues.
|
||||
|
||||
### **Linux Gaming Laptop**
|
||||
|
||||
![][11]
|
||||
|
||||
Most of the time, with gaming laptops, you'll have to manually tweak things a bit. And those 'things' are mostly associated with the GPU. It can be as simple as installing the proprietary driver, to dealing with a system that refuses even to boot into the live CD/USB. But with enough patience, most of the time, they can be fixed. If your gaming laptop comes with a very recently released Nvidia/AMD GPU and if the issue is related to the driver, then fixing it simply means waiting for an updated driver. Sometimes that can take time. But if you buy a laptop with a GPU that's released a couple of months ago, then that alone should increase your chances of fixing any existing issues to a great degree.
|
||||
|
||||
So with that in mind, I've chosen the [Dell Inspiron i5577-7342BLK-PUS][12] as the gaming laptop choice. It's a powerful gaming laptop that has a power tag below 1000 bucks. The reason being is the 15.6″ FullHD (1920 x 1080) display mostly. Because when you look at the rest of the configuration (yes you can further customize it), it includes a 7th generation Core i7 CPU (quad-core), 16GB DDR4 RAM (up to 32GB), 512GB SSD drive and an Nvidia GTX 1050 GPU which has received lots of positive reviews. You won't be able to play high-end games in QHD or 4K resolutions with it say on an external display, but it can handle lots of games in FullHD resolution on its 15.6″ display nonetheless.
|
||||
|
||||
And the other reason I've chosen a Dell over the other is, for some reason, most Dell laptops (or computers in general) are quite compatible with 'Linux'. It's pretty much the same with this one as well. I've manually checked the hardware details on Dell, while I cannot vouch for any issues you might come up with that Nvidia GPU, the rest of the hardware should work very well on major 'Linux' distributions (such as with Ubuntu for instance).
|
||||
|
||||
### **Is that it?**
|
||||
|
||||
Actually yes, because I believe less is better.
|
||||
|
||||
Look, I could've added bunch of laptops here and thrust them at you by 'recommending' them. But I take very seriously what I do on this blog. So I can't just 'recommend' 10-12 laptops unless I'm confident that they're suited to run 'Linux' as smoothly as possible. While the list is at the moment, confined to 3 laptops, I've made sure that they will run 'Linux' comfortably (again, even with the gaming laptop, apart from the Nvidia GPU, the rest of the hardware SHOULD work), plus, the three models should cover requirements of a large audience in my opinion. That said, as time goes on, if I find laptops from other manufactures I can predict with confidence that will run 'Linux' quite well, then I'll add them. But for now, these are my recommendations. However, if you're not happy with these recommendations, then below are couple of simple things to look for. Once you get the basic idea, you can pretty easily predict with good accuracy whether a laptop is going to give you a difficult time running 'Linux' or not. I've already mentioned most of them above, but here they are anyway.
|
||||
|
||||
* **Find more information about the hardware:**
|
||||
|
||||
|
||||
|
||||
When you come up with a laptop take a note of its model. Now, on most websites, details such as the manufacturer of the Wireless adapter or the audio chip etc aren't given. But on most occasions such information can be easily extracted using a simple trick. And this is what I usually do.
|
||||
|
||||
If you know the model number and the manufacturer of the laptop, just search for its drivers in Google. Let's take the Dell gaming laptop I just mentioned as an example. If you take its name and search for its drivers in Google ('`Dell Inspiron i5577-7342BLK-PUS drivers`'), Google doesn't display an official Dell drivers page. This is not surprising because Dell (and other manufactures) sell laptops under the same generic model name with few (2 or three) hardware variations. So, to further narrow things down, starting from the left side, let's use the first three fields of the name and search for its drivers in Google ('`Dell Inspiron i5577 drivers`'), then as shown below, Google lists us, among other websites, an official Dell's drivers page for the Inspiron 5577 (without the 'i').
|
||||
|
||||
![][13]
|
||||
|
||||
If you enter into this page and look around the various drivers & hardware listed there and compare them with the model we're interested in, then you'll see that the hardware listed in the '`Dell Inspiron i5577-7342BLK-PUS`' are also listed there. I'm usually more keen to look for what's listed under 'audio' & 'network', because the exact model names of these chips are the most difficult to obtain from a buyer's website and others such as the GPU, CPU etc are listed. So if you look what's displayed under 'network' then you'll see that Dell gives us couple of drivers. One is for Realtek Ethernet adapter (Ethernet adapter are usually well supported in 'Linux'), Qualcomm QCA61x4A-QCA9377 Wireless adapter (if you further research the 'QCA61x4A' & 'QCA9377' separately, because they're separated by '-', then you'll find that these are actually two different yet very similar Wireless chips from Qualcomm. In other words, Dell has included two drivers in a single package), and couple of Intel wireless adapters (Intel hardware too is well supported in 'Linux').
|
||||
|
||||
But Qualcomm devices can sometimes give issues. I've come up with one or two, but none of it were ever major ones. That said, when in doubt, it's always best to seek. So take that 'Qualcomm QCA61x4A-QCA9377' (it doesn't really matter if you use one adapter or use the two names combined) and add to it a keyword like 'linux' or 'ubuntu' and Google it. If I search for something like 'Qualcomm QCA61x4A-QCA9377 ubuntu' then Google lists few results. The first one I get is from [AskUbuntu][14] (a community driven website dedicated to answer end-user's Q & A, excellent resource for fixing issues related to Ubuntu).
|
||||
|
||||
![][15]
|
||||
|
||||
If you go over to that page then you can see that the user complains that Qualcomm QCA9377 wireless adapter is giving him hard time on Ubuntu 15.10. Fortunately, that question has been answered. Plus, this seems to be an issue with Ubuntu 15.10 which was released back in October 2015, so this is two years ago. So there is a high probability that this particular issue is already fixed in the latter Ubuntu releases. Also remember that, this issue seem to related to the Qualcomm QCA9377 wireless chip not the QCA61x4A. So if our 'Linux' gaming Dell laptop has the latter chip, then most probably you wouldn't come up with this at all.
|
||||
|
||||
I hope I didn't over complicate things. I just wanted to give you a pointer on how to find subtle details about the hardware of the laptop that you're hoping to run 'Linux', so that you can better evaluate the situation. Use this technique with some common sense, and with experience, you'll become very efficient at it.
|
||||
|
||||
* **Don 't stop at the GPU & the Network Adapter:**
|
||||
|
||||
|
||||
|
||||
![][16]
|
||||
|
||||
While its true that the GPU and the Network adapter are among the two most common hardware devices that give you big issues in 'Linux' since you're buying a laptop, it's always good practice to research the compatibility of the audio, the touch-pad and the keyboard & its associated features (for instance, my old Dell's Backlit keyboard had a minor issue under 'Linux'. Backlit keyboards can give minor issues in 'Linux', again, it's from experience) as well.
|
||||
|
||||
* **If it 's too 'hot', wait 2-3 months:**
|
||||
|
||||
|
||||
|
||||
As far as the computer end-users are concerned, the market share of 'Linux' is quite small. Therefore, hardware manufacturers don't take 'Linux' seriously, yet. Thus, it take them a bit longer to fix any existing major issues with the drivers of their recently released hardware devices. This is even true to open-source drivers also, but they tend to come up with 'fixes' fast compared to proprietary ones in my experience. So, if you're buying a laptop that features hardware devices (mainly CPU & the GPU) that have been very recently released, then it's better to wait 2 or 3 months before buying the laptop to see if there are any major issues in 'Linux'. And hopefully by that time, you'll be able to find a fix or at least to predict when the fix is mostly likely to arrive.
|
||||
|
||||
* **What about the Screen & HiDPI support in 'Linux'?**
|
||||
|
||||
|
||||
|
||||
![][17]
|
||||
|
||||
'Pixel density' or 'High Pixel Density' displays are quite popular terms these days. And most people assume that having lots of pixels means better quality. While that maybe true with the common intuition, technically speaking, it's not accurate. This subject can be bit too complicated to understand, so I'll just go ever the basics so that you'll know enough to avoid unnecessary confusion.
|
||||
|
||||
Things that are displayed on your screen such as texts and icons are designed with certain fixed sizes. And these sizes are defined by what is called 'Dots per inch' or 'DPI' for short. This basically defines how many dots (pixels) there should be per inch for these items to appear correctly. And 72 dots per inch is the standard set by Apple and that's what matters. I'm sure you've heard that Windows use a different standard, 96 dots per inch, but that is not entirely correct. I'm not going to go into the details, but if you want to know more, [read Wikipedia][18]. In any case, all that you want to know to make sure that the display screen of your 'Linux' laptop is going to look sharp and readable simultaneously, is to do the following. First take a note of its size (13.3″, 15.6″, 17″…) and the resolution. Then go to [PXCALC.com][19] website which gives you a nice dots per inch calculator. Then enter the values in the correct fields. Once done, take a note of the DPI value the calculator gives you (it's on the top right corner, as shown below). Then take that value and simply divide it by 72, and here's the crucial part.
|
||||
|
||||
![][20]
|
||||
|
||||
If the answer you get resembles an integer increase such as 2, 3, 4 (+0.2 -- 0.2 variation is fine. The best ones may give you +0.1 -- 0.1 variation only. The finest will give you near 0.0 ones, such as the iMac 27 5K) then you have nothing to worry about. The higher the integer increase is (provided that the variation stays within the margins), the more sharper the screen is going to be. To give you a better idea, let's take an example.
|
||||
|
||||
Take the first laptop I gave you (Dell XPS 13.3″ with the QHD resolution) as an example. Once you're done with the calculation it'll give you answer '3.83' which roughly equals to '3.8' which is not an integer but as pointed out, it's safely within the margin (-0.2 to be precise). If you do the same calculation with the Acer laptop I recommend to you as the best cheapest option, then it'll give you a value of '1.95' which is roughly '2.0'. So other features (brightness, viewing angle etc) aside, the display on Dell is almost twice as sharp compared to Acer (trust me, this display still looks great and sharp. It'll look far better compared to a resolution of 1366 x 768 on either a 13.3″ or a 15.6″ screen).
|
||||
|
||||
* **RAM Size?**
|
||||
|
||||
|
||||
|
||||
![][21]
|
||||
|
||||
KDE and GNOME are the two most popular desktop environments in 'Linux'. While there are many others, I advice you to stick with one of them. These days my preference lies with KDE. KDE plasma is actually more lightweight & efficient compared to GNOME, as far as I can tell. If you want some numbers, then in [my Ubuntu 16.10 flavors review][22] (which is about an year old now), KDE plasma consumed about 369 MiB while GNOME edition of Ubuntu consumed 781 MiB! That's **112% increase!**
|
||||
|
||||
These days I use Kubuntu 17.10, although I haven't reviewed it, but I can tell that its memory consumption too is somewhere around 380-400 MiB. Coming back to the point, I would like to advice you **not to go below 8GB** when it comes to choosing RAM size for your 'Linux' laptop. That way, I can guarantee with great probability that you'll be able to use it for at least 4 years into the future without having to worry about laptop becoming slow and not being able to cope with the requirements set by distribution vendors and by most end-users.
|
||||
|
||||
If you're looking for **a laptop for gaming in 'Linux'**, then of course you should **go 12GB or more**. Other than that, 8GB is more than enough for most end-user needs.
|
||||
|
||||
* **What about an SSD?**
|
||||
|
||||
|
||||
|
||||
![][23]
|
||||
|
||||
Despite what operating system you use, adding an SSD will improve the overall performance & responsiveness of your laptop immediately because they are much faster than the rotational disks, as simple as that. That being said, in my experience, even though efficient and lightweight, KDE distributions take more time to boot compared to GNOME counterparts. Some 'Linux' distributions such as Ubuntu and Kubuntu come with a especially designed utility called 'ureadahead' that improves boot-up times (sometimes by **30%** or even more), unfortunately not all distributions come with such tools. And on such occasions, **KDE can take 50 seconds+ to boot on a 5400 rpm SATA drive**. [Manjaro 17.0.2 KDE][24] is one such example (shown in the graph above).
|
||||
|
||||
Thus, by simply making sure to buy a laptop that features an SSD can immensely help you out. **My Kubuntu 17.10 is on a smaller SSD drive (20GB) and it boots within 13-15 seconds**.
|
||||
|
||||
* **The GPU?**
|
||||
|
||||
|
||||
|
||||
As mentioned many time, if possible, always go with an Intel GPU. Just like Dell who's known to produce 'Linux friendly' hardware, Intel has also thoroughly invested in open-source projects, and some of its hardware too is such like. You won't regret it.
|
||||
|
||||
* **What about automatic GPU switching (e.g: Nvidia Optimus), will it work?**
|
||||
|
||||
|
||||
|
||||
If you're bought a laptop with a discreet graphics card, then in Windows, Nvidia has a feature called 'Optimus' which automatically switch between the integrated (weak) GPU and the discreet (more capable) GPU. ATI also has this capability. There is no official support of such features in 'Linux', but there are experimental work such as the [Bumblebee project][25]. But it does not always work as expected. I simply prefer to have installed the proprietary GPU driver and switch between each whenever I want, manually. To their credit, Fedora team has also been working on a solution of their own, I don't honestly know how far they've gone. Better [ask Christian][26] I guess.
|
||||
|
||||
* **Can 'Linux' give you good battery life?**
|
||||
|
||||
|
||||
|
||||
Of course it can! Once your hardware devices are properly configured, I recommend that you install a power usage optimizer. There are a few applications, but I recommend '[TLP][27]'. It's easy to install, cuts down the power usage impressively in my experience, and usually it requires no manual tweaks to work.
|
||||
|
||||
Below are two screenshots from my latest Ubuntu 17.10 review. First screenshot shows the power usage before installing 'tlp' and the second one shows the readings after installing it (the pictures say it all):
|
||||
|
||||
![][28]
|
||||
|
||||
![][29]
|
||||
|
||||
'tlp' should be available in major 'Linux' distributions. On Ubuntu based ones, you should be able to install it by issuing the following commands:
|
||||
|
||||
`sudo apt update`
|
||||
|
||||
`sudo apt install tlp`
|
||||
|
||||
Now reboot the computer, and you're done!
|
||||
|
||||
* **How did you measure the power usage in 'Linux'?**
|
||||
|
||||
|
||||
|
||||
Glad you asked! It's called '[powerstat][30]'. It's this amazing little utility (designed by Colin King, an Ubuntu developer) that gathers useful data that's related to power consumption (and debugging) and puts them all into a single screen. On Ubuntu based systems, enter the below commands to install it:
|
||||
|
||||
`sudo apt update`
|
||||
|
||||
`sudo apt install powerstat`
|
||||
|
||||
Most major 'Linux' distributions make it available through their software repositories these days.
|
||||
|
||||
* **Are there any 'Linux' operating systems you recommend?**
|
||||
|
||||
|
||||
|
||||
Well, my main operating system these days is Kubuntu 17.10. Now I have not reviewed it, but to make a long story short, I love it! It's very easy to install, beginner friendly, stable, beautiful, power efficient and easy to use. These days I literally laugh at GNOME! So if you're new to 'Linux', then I advice you to [try Kubuntu ][31] or [Linux Mint][32], first ('Mint' gives you couple of desktop choices. Go with either the KDE version or with 'Cinnamon').
|
||||
|
||||
Then once you get the hang of things, then you can move on to others, that's the best approach for a beginner.
|
||||
|
||||
### **Final Words**
|
||||
|
||||
Recall what I said at the beginning. If you're looking for a laptop that runs 'Linux' almost effortlessly, then by all means go with the [Dell XP S9360-3591-SLV][2]. It's a well build, powerful, very popular, ultra-portable laptop that not only can let you run 'Linux' easily, but also feature a great display screen that has been praised by many reviewers. If however, you want something cheap, then go with the [Acer Aspire E 15 E5-575G-57D4][6]. As far as 'Linux' compatibility goes, it's almost as good as the Dell, plus it's a great value for the money.
|
||||
|
||||
Thirdly, if you're looking for a laptop to do some gaming on 'Linux', then [Dell Inspiron i5577-7342BLK-PUS][12] looks pretty solid to me. Again, there are many other gaming laptops out there, true, but I specifically chose this one because, it features hardware that are already compatible with 'Linux', although I cannot vouch for the Nvidia GTX 1050 with the same confidence. That said, you shouldn't buy a 'Linux' gaming laptop without wanting to get your hands dirty a bit. In that case, if you're not happy with its hardware capabilities (it's quite capable) and would like to do the research and choose a different one, then by all means do so.

I wish you good luck with your purchase and thank you for reading!

2017-2018 年度最佳 Linux 笔记本电脑:一个来自 RHCE 购买者的挑选指南
|
||||
======
|
||||
![][1]
|
||||
|
||||
如果你不具备相关的知识和经验,挑选出最适合 Linux 的笔记本电脑,可能是件很困难的事。并且,看上去你买了一台配置、功能、性能都很棒的电脑,但是,却疲于处理各种 ‘Linux’ 的问题,对于一个 **RedHat 认证工程师** 来说,这是一件相当丢人的事情,这篇文章的作者兼博主,是一个 **有 14 年以上 ' Linux' 使用经验的用户**,我用我掌握的一些知识去为你推荐一些笔记本电脑,我可以保证我推荐的这些电脑,'Linux' 在它上面会跑的很好。我研究了 20 多个小时之后(通过认真了解硬件详细情况和用户反馈),我选择 [Dell XP S9360-3591-SLV][2] 作为我的首选推荐。如果你希望笔记本电脑装备最新的功能特性,并且 **用于在 Linux 上工作** 时有极好的性能,那么,这台笔记本电脑将是你的最佳选择。
|
||||
|
||||
它使用铝合金机身,很轻(2.7 磅重),有强劲的硬件性能,待机时间较长,使用康宁大猩猩玻璃的 QHD 显示屏,分辨率为 3200×1800、并且还具备触控功能,可以为你带来清晰的图像表现,即便是很小的细节也可以很好的展现出来,有一个带橡皮掌托的、面积很大的并且非常好用的触摸板(早期版本上触摸板有几个小问题,但是,最新的机器已经修复了),并且也有一个很好用的带背光的键盘(按键的行程很短,这一点有些像 thinkpad 笔记本),两个 USB 3.0 端口。最重要的是,两个最让 ‘Linux’ 用户头痛的问题,无线网卡和 GPU (Intel HD Graphics 620 **播放 4K 视频可以达到 60 fps**),在这台 Dell 电脑上,它们都 **超级兼容 'Linux'**。
|
||||
|
||||
![][3]
|
||||
|
||||
![][4]
|
||||
|
||||
有一个缺点是,它没有 HDMI 端口。在这个位置,Dell 增加了一个 Thunderbolt 3 端口。因此,你唯一的选择是使用一个 Thunderbolt 到 HDMI 的转换器(它很便宜)。第二,在购买之后,你不能升级它的 8GB 的内存(在采购之前你可以改变硬件配置 -- CPU、RAM & SSD),但是,在我的选择中,8GB 的内存运行任何 ‘Linux’ 分发版做任何工作都足够了。我有一台 Asus 笔记本电脑(它是我收到的一份礼物)使用第五代的 Core i7 的 CPU,4GB 内存,它是我主要使用的计算机。使用 Chrome 可以打开 15-20 个标签,VLC 在后台运行,打开文件管理和一个代码编辑器,这种情况下,它工作的很好。如果我减少一些浏览器标签(减少到 4-5 个),然后,即便是其它的应用程序都打开的情况下,我都可以在 Virtualbox 上使用虚拟机工作。这些都是在 4GB 内存的情况下,因此,有 8GB 内存和其它更强劲的硬件的情况下,你绝对工作的非常好的。
|
||||
|
||||
> **注意:** 虽然我为你选择了一套非常可靠的 [硬件][2],但是,如果你愿意,你仍然可以进一步去定制它。即便你不去选择 '8GB RAM/128GB SSD' 这个选项。因为,那个版本也提供 1920×1080 的 FHD 显示屏,并且,在 13.3″ 的显示屏上让菜单看起来更小一些,看起来稍微有点困难。
|
||||
|
||||
###**最便宜的 Linux 笔记本电脑**
|
||||
|
||||
![][5]
|
||||
|
||||
如果你觉得这台 Dell 笔记本电脑有点贵,买不起,但是还想拥有类似的非常好的性能,并且与 'Linux‘ 的兼容性很好,那么,第二个最佳选择是这台 [Acer Aspire E 15 E5-575G-57D4][6]。它 15.6″ 的显示屏,无疑能提供像前面的 Dell 笔记本一样的显示表现,但是,在 15.6” 上的 1920×1080 的全高清分辨率显示屏,也可以让任何细节都显示的非常清晰。其它的硬件与前面介绍的很贵的 Dell 笔记本电脑很相似,但是,**因此它的电池很重,整机重达 5.2 磅。**
|
||||
|
||||
你实际上可以去做一些定制。基本的配置包括一个第七代 Core i5 CPU,15.6“ 的全高清显示屏(1920 x 1080),8GB DDR4 内存,256GB 固态硬盘,Intel HD Graphics 620 GPU 和一个独立的 Nvidia 940 MX GPU,端口方面:HDMI 2 USB 3.0,1 x USB 2.0 & 1 USB 3.1。对于 $549 的售价,它竟然 **包含一个 DVD 刻录机** … [**它是一个特价商品**][6]。
|
||||
|
||||
至于 'Linux' 的兼容性,它真的很好。虽然它不像顶级的 Dell XPS,但是,至少在我看来,如果它能够解决 Nvidia GPU 的问题,它就是一个很好的选择。除了一个用户以外,所有其它的用户都反馈,它的 'Linux' 兼容性非常好。唯一的一个用户抱怨说,在 Linux Mint 上安装了 Nvidia 的专用驱动以后,出现了一个小问题,并且他说,他决对不是故意 “抹黑” 它。这个反馈与我在使用移动版的 Nvidia GPU 所遇到的情况一样。
|
||||
|
||||
例如,现在我使用一台 Asus 笔记本电脑,并且它除了集成的 Intel GPU 以外,它也有一个独立的 Nvidia 920M GPU。这台笔记本电脑我大概已经用了一年半时间了。[我在它上面运行了一些 'Linux' 分发版][7],并且,遇到的唯一的问题是,[在 Ubuntu 17.10 上][8] 安装完它的专用驱动程序后,如果激活 Nvidia 作为默认的 GPU,自动用户登入功能会停止工作。因此,每次进入桌面我都要输入我的登陆凭据。这虽然不是一个大问题,但是,我确信,它可以通过编辑一些登陆管理器的配置设定来修复它,但是,我根本就没有去理它,因为我很少使用 Nvidia GPU。因此,我只是简单地改变默认 GPU 为 Intel,所有的一切就会正常。因此,前段时间,我在 [Ubuntu 16.04 LTS][10] 上 [的同一个 Nvidia GPU 上启用了’运动插值‘][9],并且它处理的非常好!
|
||||
|
||||
我想说的是,GPU 驱动,比如 Nvidia & AMD/ATI 提供的,给用户带来困扰只是在过去的 'Linux' 上,但是,现在随着进一步的处理,已经不是什么困难的事情了,或者说,至少没有像以前那样困难了。除非你使用的是一个非常新的高端 GPU,'Linux' 还是有可能在没有大的问题的情况下运行的。
|
||||
|
||||
###**Linux 游戏笔记本**
|
||||
|
||||
![][11]
|
||||
|
||||
很多时候,玩游戏的笔记本电脑,你需要去手动调整一些东西。并且,这些 “东西” 大部分都是与 GPU 相关的。它可能只是简单地安装一些专用的驱动程序,去处理一个拒绝引导到 CD/USB 中的系统。但是,如果有足够的耐心,大多数情况下,它们都是可以修复的。如果你的游戏笔记本有一个非常新的 Nvidia/AMD GPU 驱动,并且,这个驱动有问题,那么,修复它意味着只需要等待它更新驱动程序。有时候,可能需要等待很长的时间。但是,如果你买了一台安装有几个月前发行的 GPU 的笔记本电脑,那么,仅此一点,就大大增加你解决现有问题的机会。
|
||||
|
||||
因此,考虑到这一点,我选择了 [Dell Inspiron i5577-7342BLK-PUS][12],作为一个游戏笔记本电脑的最佳选择。它是一台强大的游戏笔记本电脑,售价低于 1000 美元。主要原因是它有一个 15.6″ 的全高清(1920 x 1080)显示屏。因为,在你查看其它配置的时候你会发现(也可以进一步定制它),它包含一个第七代 Core i7 CPU(四核心),16GB DDR4 内存(最高可到 32GB),512GB SSD 驱动器,并且有一块 Nvidia GTX 1050 GPU,它有很多积极的评价。你只可以在 QHD 或者 4K 下,使用外接显示器去玩高端游戏,尽管如此,它也可以在 15.6″ 的全高清分辨率下处理一些游戏。
|
||||
|
||||
我选择 Dell 的另外原因是,大多数的 Dell 笔记本电脑(或者一般用途的计算机)都是非常兼容 'Linux' 系统的。我在 Dell 网站上手工检查了硬件配置的详细情况,虽然我不能保证使用 Nvidia GPU 不会有任何问题,其它的硬件在主流的 'Linux' 发行版上都工作的很好(比如 Ubuntu)。
|
||||
|
||||
###**哪个才是你需要的?**
|
||||
|
||||
实际上,我相信越少越好。
|
||||
|
||||
我可以在这里给你 ’推荐‘ 很多很多的笔记本电脑,但是,那样的话,我需要写一系列的博客文章。因此,我并不打算’推荐‘ 10-12 台笔记本电脑,除非我确信它们都在 ’Linux‘ 上运行的非常好。而目前为止,这个推荐清单上只有 3 台。我能确信它们在 'Linux' 上运行的非常好(而且,甚至是游戏笔记本电脑,除了 Nvidia GPU,其它的硬件部分应该工作的很好),再加上,这三个型号都有很多的可选项。换句话说就是,随着时间的推移,如果我从其它的制造商的产品中找到一些笔记本电脑,我相信它们在 'Linux' 上也运行的很好,然后,我也会推荐它们。但是,现在,就这三台笔记本电脑是我所推荐的。你可能不喜欢这个推荐的电脑,那么,下面我告诉你如何去查找你心仪的笔记本电脑。一旦你有了基本的概念,你可以非常容易地去预测,一台笔记本电脑是否能够运行 'Linux' 而不会出现问题。上面我已经提到了大部分,但是,我还在这里再说一下。
|
||||
|
||||
* **查找关于硬件的更多信息:**
|
||||
|
||||
|
||||
|
||||
当你拿到一个笔记本电脑时,记下它的型号。现在,在大多数的网站上,都提供硬件的详细情况,比如,无线网卡或者声卡芯片的制造商。在大多数的情况下,使用一些简单的技巧就可以拿到这些信息。我通常是这样做的。
|
||||
|
||||
如果你知道笔记本电脑的制造商和型号,可以在 Google 中搜索它的驱动程序。我以前面的 Dell 游戏笔记本电脑为例。如果你知道它的名字,然后在 Google 上去搜索它的驱动程序(`Dell Inspiron i5577-7342BLK-PUS drivers`),Google 并不显示一个 Dell 的官方的驱动程序页面。这并不奇怪,因为 Dell (以及其它制造商)在一个通用的型号名字下面,销售很多种装有各种不同的(2 到 3 种)硬件的笔记本电脑。因此,去缩小搜索目标,从左侧开始,我们首先来使用名字的前三个字段,并且用它在 Google(`Dell Inspiron i5577 drivers`)中搜索驱动程序,然后,如下所显示,并且,Google 也列出了不同的所属网站,对于 Inspiron 5577(没有'i'),列出了一个 Dell 的官方驱动程序页面。
|
||||
|
||||
![][13]
|
||||
|
||||
如果你进入这个页面,去查看各种我们感兴趣的型号的驱动程序和硬件列表,那么,你将看到在 `Dell Inspiron i5577-7342BLK-PUS` 中的硬件也在这里列出来了。我通常只喜欢查看 'audio' 和 'network' 下面列出的内容,因为从购买网站上去获得这些芯片的准确的型号名一般很困难,其它的一些硬件如 GPU、CPU 等等也列了出来。因此,如果你查看在 'network' 下显示的内容,你将看到 Dell 提供的一些驱动程序。其中一个就是 Realtek 以太网适配器(在 'Linux' 中以太网适配器通常都支持),Qualcomm QCA61x4A-QCA9377 无线网络适配器(如果你进一步研究,需要对 'QCA61x4A' 和 'QCA9377'分别进行,因为它们之间用 '-' 分隔,你就会发现,它们实际上是来自高通的两种不同的无线芯片。这个关键字表示,Dell 在一个包中包含了两种驱动程序),和一组 Intel 无线网络适配器(Intel 硬件在 'Linux' 中也支持的非常好)。
|
||||
|
||||
但是,高通的设备有时候可能会有些问题。我遇到过一两个,但是,它们都不是什么严重的问题。也就是说,当有问题时,去查找就是解决的一个好办法。因此,使用 'Qualcomm QCA61x4A-QCA9377' 做为关键字(使用一个适配器或者使用一个芯片名字的组合去查询这并不重要),并且增加一个像 'linux' 或者 'ubuntu' 这样的关键字在 Google 中去搜索它。如果像 'Qualcomm QCA61x4A-QCA9377 ubuntu' 这样去搜索,然后,Google 会列出很多结果。我收到的第一个结果是自来 [AskUbuntu][14](一个社区驱动的网站,专门回答终端用户提出的问题,是一个解决 Ubuntu 相关问题的极好的资源)。
|
||||
|
||||
![][15]
|
||||
|
||||
如果你去看那个页面,你可以看到有用户报怨 Qualcomm QCA9377 无线网络适配器在它的 Ubuntu 15.10 不能正常工作。幸运的是,那个问题已经被回答了。这个问题看起来似乎是 Ubuntu 15.10 的问题,它发布于 2015 年 10 月,因此,这是两年前的问题了。所以,这个问题很可能在最新的 Ubuntu 发行版中已经修复了。我还记得,这个问题好像与 Qualcomm QCA9377 无线芯片有关,而不是 QCA61x4A。因此,如果我们的 'Linux' 游戏笔记本电脑使用的是后面型号的无线芯片,那么很有可能你不会遇到这个问题。
|
||||
|
||||
我希望我不要遇到上面报怨的所有事情。我只是想给你提供一个指南,告诉你如何去找到你希望去运行 'Linux' 的笔记本电脑上的关于硬件的详细情况,这样你就可以很好地去评估它。使用一些常识性的技巧和经验,你的工作效率将会更高。
|
||||
|
||||
* **不要停留在 GPU 和网络适配器上:**
|
||||
|
||||
|
||||
|
||||
![][16]
|
||||
|
||||
虽然,在你购买了一台笔记本电脑来运行 ’Linux‘ 时,GPU 和网络适配器是大多数人遇到的最容易出现问题的硬件设备,但是,去研究音频、触控板、和键盘在 ’Linux’ 中的兼容性和它们相关的特性(例如,我的老 Dell 的背光键盘在 ‘Linux’ 中也有一个小问题),也是一个很好的实践。
|
||||
|
||||
* **如果它是一个 '热门' 硬件,等待 2-3 个月:**
|
||||
|
||||
|
||||
|
||||
正如,计算机终端用户所担心的那样,'Linux' 的市场份额是非常小的。因此,硬件制造商并没有提供 'Linux' 系列的驱动程序。因此,他们修复最新发布的硬件设备中已存在的主要问题需要很长的一段时间。即便是开源驱动程序,也是如此,当然,在我的经验中,开源的驱动程序的问题修复比专用的要快。因此,如果你买的笔记本电脑的特色硬件设备(主要指 CPU 和 GPU)是最新发行的,那么,它通常需要等待 2 或 3 个月才能去修复在 ‘Linux’ 上的主要的问题。并且,但愿在那个时候,你可以找到一个修复,或者,至少可以预测什么时候可以被修复。
|
||||
|
||||
* **关于屏幕和 HiDPI 在 'Linux' 上支持的怎么样?**
|
||||
|
||||
|
||||
|
||||
![][17]
|
||||
|
||||
'像素密度' 或者 '高像素密度' 显示是最近非常流行的术语。并且大多数人都认定,更高的像素意味着更好的质量。虽然在一般的认知和技术角度上,它可能是正确的,但是,它并不准确。这个主题理解起来很复杂,因此,我将只讲一些基本的概念,对于你理解这个主题已经足够了,以避免不必要的混乱。
|
||||
|
||||
任何显示在你的屏幕上的东西,比如文本或者图标,都被设计为某些固定的大小。而这些大小是通过被称为 “每英寸显示的像素点数” 或者简称为 DPI 来描述的。它基本上定义了每英寸应该显示多少个点(像素)才能正确显示这个东西。每英寸显示 72 个点是由 Apple 公司制定的标准,这是很重要的。我相信,你可能听说过,Windows 使用了一个不同的标准,每英寸 96 个点,但是,它不完全正确。我不去深入其中的细节,但是,如果你想进一步了解更多的内容,[阅读 Wikipedia][18]。在任何情况下,要确保显示在你的 ‘Linux’ 笔记本电脑的屏幕上的内容,看起来清晰可读,如果你想了解,按以下的内容去做。首先,确定它的显示大小(13.3″、15.6″、17″…)和分辨率。然后到 [PXCALC.com][19] 网站,它提供一个非常好用的很英寸点数计算器。接着在上面输入正确的内容。计算完成后,它告诉你一个 DPI 的计算结果(在它的右上角,如下图所示)。然后将那个值简单地除以 72,这就是最重要的部分。
|
||||
|
||||
![][20]
|
||||
|
||||
如果你得到的结果是一个类似于增加的整数,比如 2、3、4(+0.2 到 —0.2 的变化是很好的,最好的一个可能是 +0.1 到 —0.1。最完美的是接近 0.0,比如, iMac 27 5K),然后,你就没有什么可担心的了。整数增加越高(只要变化保持在页边的空白范围之内),屏幕越清晰。为了更好理解,我们举一个例子。
|
||||
|
||||
我以推荐给你的第一个笔记本电脑(使用 13.3″ 的 QHD 分辨率的 Dell XPS)为例。如果你使用这个计算器去计算,它的结果是 '3.83',把它粗算为 '3.8',它不是我们前面所说的那样一个整数,但是,它在页边空间范围以内(-0.2),是安全的。如果你拿我推荐的 Acer 笔记本电脑做同样的计算,它得到的结果是'1.95',把它粗算为 '2.0'。因此,在不考虑它的其它特性(亮度,可视角度,等等)的情况下,Dell 笔记本电脑上的显示清晰度要好于 Acer 几乎两倍(相信我,这个显示效果已经看起来非常清晰了。但是,它相比分辨率为1366 x 768 的无论是 13.3″ 还是 15.6″ 的屏幕,看起来显示效果更好)。
|
||||
|
||||
* **关于内存大小?**
|
||||
|
||||
|
||||
|
||||
![][21]
|
||||
|
||||
KDE 和 GNOME 是在 'Linux' 上的两种主流的桌面环境。虽然还有很多其它的选择,我建议你坚持使用其中的一个。目前来说,我比较偏爱 KDE。据我所知,KDE plasma 比 GNOME 更加轻量化,并且效果更好。如果你希望了解它们之间的比较数据,它在 [我的 Ubuntu 16.10 特点评估][22] 中(它大概是在一年前做的),在 Ubuntu 上 KDE plasma 占用大约 369 MiB 内存,而 GNOME 大概占用了 781 MiB!那是 **112% 减少!**
|
||||
|
||||
现在我使用 Kubuntu 17.10,虽然我没有评估它,但是我可以告诉你,它的内存占用大约在 380-400 MiB左右。重新回到这个话题上,我建议你在为你的 'Linux' 笔记本电脑的内存选择上,**不要低于 8GB**。那样,我可以很自信地保证,在未来 4 年内你的笔记本电脑都运行的很好,而不用担心它会变慢,并且可以去很好的使用各种发行版和满足大多数终端用户的需求。
|
||||
|
||||
如果你是在寻找一台 **在 'Linux' 上玩游戏的笔记本电脑**,那么内存选择应该是 **使用 12GB 或者更多**。 除比之外,8GB 内存对于大多数终端用户来说是足够的。
|
||||
|
||||
* **关于 SSD**
|
||||
|
||||
|
||||
|
||||
![][23]
|
||||
|
||||
不管你使用的是什么操作系统,增加一块 SSD 将能提升你的笔记本电脑的整体性能和反应速度,因为它比起普通的机械硬盘来说速度快很多,就这么简单。也就是说,在我的经验中,即便是高效和轻量化的 KDE 发行版,相比 GNOME 要花更多的启用时间。一些 'Linux' 发行版,比如 Ubuntu 和 Kubuntu 带着一个特别设计的被称为 'ureadahead' 的实用程序,它可以改善启动时间(有时可以达到 **30%** 甚至更多),不幸的是,并不是所有的发行版都有这类工具。在有些时候,**安装在 SATA 驱动器上的 KDE 的启动时间可能长达 50 秒以上**。[Manjaro 17.0.2 KDE][24] 就是其中一个这样的例子(显示在上面的图表中)。
|
||||
|
||||
因此,最简单的方法就是购买一台带有 SSD 的笔记本电脑,它可以帮助改善启动时间。**我的 Kubuntu 17.10 上是一个小的 SSD 驱动器(20GB),它的启动时间在 13-15 秒内**。
|
||||
|
||||
* **关于 GPU?**
|
||||
|
||||
|
||||
|
||||
正如上面多次提到过的,如果可能,尽量使用一个 Intel GPU。正如众所周知的那样,Dell 的产品在硬件上都是 'Linux 友好的', Intel 也在开源项目上大量进行投资,并且,其中它的一些硬件也如此。选择它你不会后悔的。
|
||||
|
||||
* **如何进行自动 GPU 切换(比如: Nvidia Optimus),它能正常工作吗?**
|
||||
|
||||
|
||||
|
||||
如果你希望购买的笔记本电脑,显卡在各方面都考虑的比较周全,那么,在 Windows 中,Nvidia 有一个叫做 'Optimus' 的特性,它自动在集成 GPU(性能较弱) 和独立 GPU(性能更强)之间切换。ATI 也有这个功能。在 'Linux' 中这个功能并没有被官方支持,但是,在那方面有一个创新性的工作,比如 [Bumblebee 项目][25]。但是它并不总是按预期工作。我比较喜欢去安装专用的 GPU 驱动程序,并且在我需要的时候去手动切换它们。值得称赞的是,Fedora 团队已经做出了它们的解决方案,我并不知道他们做的怎么样,我猜它很好,[ask Christian][26]。
|
||||
|
||||
* **'Linux' 能给你更长的电池使用时间吗?**
|
||||
|
||||
|
||||
|
||||
当然可以!只要你的硬件设备配置正确,我建议你安装电源使用优化器。现在有几个这方面的应用程序,但是,我建议使用 '[TLP][27]'。它很容易安装,在我的经验中它可以使功耗降低,而且结果令人影响深刻,它不需要手动去调整什么就可以正常工作。
|
||||
|
||||
下面有两张我的最新的 Ubuntu 17.10 的评估截屏。第一张截屏展示了在安装 'tlp' 之前的电源使用,而第二张展示了安装之后的(图片已经说明了一切):
|
||||
|
||||
![][28]
|
||||
|
||||
![][29]
|
||||
|
||||
'tlp' 可以在主要的 'Linux' 分发版上使用。在 Ubuntu 上,你可以通过执行下面的命令去安装它:
|
||||
|
||||
`sudo apt update`
|
||||
|
||||
`sudo apt install tlp`
|
||||
|
||||
现在重启动计算机,就可以了!
|
||||
|
||||
* **在 'Linux' 中能测量电源使用了多少吗?**
|
||||
|
||||
|
||||
|
||||
很高兴你能这样问!它的名字叫 '[powerstat][30]'。它是非常神奇的一个小实用程序(由 Colin King 设计,它是一位 Ubuntu 开发者),它采集电源消耗(和诊断)相关的使用数据,并将它们表示在屏幕上。在基于 Ubuntu 的系统上,输入下面的命令可以去安装它:
|
||||
|
||||
`sudo apt update`
|
||||
|
||||
`sudo apt install powerstat`
|
||||
|
||||
在大多数主流的 'Linux' 分发版上,它们的软件仓库中都有这个软件。
|
||||
|
||||
* **你推荐的 'Linux' 操作系统是哪个?**
|
||||
|
||||
|
||||
|
||||
很好的问题,到目前为止,我主要使用的操作系统是 Kubuntu 17.10。我没有评估过它,但是,长话短说,我喜欢它!它非常易于安装,并且对新手比较友好,稳定,漂亮,高效并且易于使用。到目前为止我不喜欢 GNOME!因此,如果你刚开始使用 'Linux',那么,我建议你去 [尝试 Kubuntu ][31] 或者 [Linux Mint][32],首先,('Mint' 可以有很多的桌面环境选择。要么使用 KDE,要么使用 'Cinnamon')。
|
||||
|
||||
然后,在你掌握使用技巧后,你就可以转移到其它的发行版上了,这是 ‘Linux' 新手最好的方法。
|
||||
|
||||
### **结束语**
|
||||
|
||||
记住我一开始说的话,如果你在寻找一台能够轻松运行 ’Linux‘ 的笔记本电脑,那么,[Dell XP S9360-3591-SLV][2] 将是你的最佳选择。它外观漂亮、功能强大、非常流行、超便携,不仅能够很轻松地运行 'Linux',而且它还有一个非常棒的,并且得到很多人赞扬的显示屏。如果,你希望有一个更便宜的选择,那么,[Acer Aspire E 15 E5-575G-57D4][6] 会满足你的要求。它也像前面的 Dell 一样,可以很好地兼容 'Linux',再加上它的性价比,它也是一个非常好的选择。
|

第三,如果你在寻找一台能够在 ’Linux‘ 上运行游戏的笔记本电脑,那么,[Dell Inspiron i5577-7342BLK-PUS][12] 看起来非常适合你。当然,还有许多其它的游戏笔记本,但是,我特别选择这一款的原因是,它的硬件特性已经与 ’Linux‘ 兼容,虽然我不能保证它与 Nvidia GTX 1050 一样。换句话说,你不应该去买一台 ’Linux‘ 笔记本去玩游戏,那样会”玷污“你的游戏水平。如果是那样的话,它的硬件性能(它的性能很强大了)并不会让你满意,如果你愿意去研究并找到其它的选择,一定 Dell去那样做吧。
