[Fixed] Keyboard And Mouse Freeze After Suspend In Ubuntu 14.04 [Quick Tip]
================================================================================
### Problem: ###
When Ubuntu 14.04 or 14.10 comes back from sleep or suspend mode, the keyboard and mouse freeze. Nothing can be clicked or entered. The only way out is to force shutdown the system by pressing the power button. This is very inconvenient, rather very annoying. Because the default behavior in Ubuntu is that when you close the lid of the laptop, it goes in sleep mode.
In this quick post, we shall see how to fix this issue of mouse freeze after suspend in Ubuntu 14.04 and 14.10.
### Solution to mouse freezing after sleep in Ubuntu 14.04 ###
The issue is actually coming from Kernel upgrade. I am not sure of the reason why, but a re-install of input device driver seems to be fixing this issue.
sudo apt-get install --reinstall xserver-xorg-input-all
This quick tip was based on a question asked by an It’s FOSS reader, Dev. Try this quick tip and see if it works for you as well. In a similar issue, you can [fix no Unity, launcher and dash after logging in to Ubuntu][1].

[已解决] Ubuntu 14.04从待机中唤醒后鼠标键盘出现僵死情况 [快速小贴士]
================================================================================
### 问题: ###
当Ubuntu14.04或14.10从睡眠和待机状态恢复时，鼠标和键盘出现僵死，不能点击也不能输入。解决这种情况是唯一方法就是按关机键强关系统，这不仅非常不便且令人恼火。因为在Ubuntu的默认情况中合上笔记本等同于切换到睡眠模式。
在这篇短文中，我们将学会如何解决Ubuntu14.04和14.10中出现的鼠标僵死问题。
### Ubuntu14.04唤醒后鼠标僵死的解决办法 ###
这个问题的是由内核升级导致的。为何导致这一情况不得而知，但是看起来好像仅需重装输入设备的驱动就能解决了。
sudo apt-get install --reinstall xserver-xorg-input-all
