ubuntu重启x server

最近ubuntu老出问题，动不动界面就不响应鼠标了，不知怎么回事，所以需要重启x，查了下这个

发现很有意思，一个fadora论坛，2004年有人问个问题，2008年被人给翻出来回答了下。 我试了一下，这个是可以的 ctrl + alt + f1 切换到终端，然后执行

sudo kill $(cat /tmp/.X0-lock)

以下是原文

Create a shell script (RestartX.sh): 
#!/bin/sh 
sudo kill `cat /tmp/.X0-lock`
startx 

~$ nohup RestartX.sh 

OR - Create some other shell script (Automate.sh): 

#!/bin/sh 
nohup RestartX.sh
~$ Automate.sh

有人看不过去这种挖坟的行为了

You guys really need glasses :) This thread is four years old! If the OP
hasn't got it figured out by now he never will. Birdy, I suggest you look
carefully at thread dates before posting. While I'm here I also suggest
reading the forum guidelines for some tips. Anything over a couple of months
old is probably already sorted out. I'm closing this thread as I'm not into
digging up the dead! Wayne
