L421 之前遇到GPU Driver update後就開不到HOME的問題

Ctrl-Alt-F1可以讓你用command mode下password進入，這樣就不會一直卡住

然後是照官方網站裡面的作法試出來的

1.移除舊的GPU driver 

（sudo sh /usr/share/ati/fglrx-uninstall.sh --force)

sudo apt-get remove --purge fglrx fglrx-amdcccle

For some users, the fglrx-updates and fglrx-amdcccle-updates packages do not work. If you attempted to install them, also do:

sudo apt-get remove --purge fglrx-updates fglrx-amdcccle-updates

2. Reboot

3.Install the driver:

1. sudo apt-get install fglrx fglrx-amdcccle

 4.Reboot 

大概就是這樣

補充一

To confirm the drivers are working open a terminal and type:

fglrxinfo

You should get an output similar to the following:

fglrxinfo 
display: :0  screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: AMD Radeon HD 6300M Series
OpenGL version string: 4.2.11733 Compatibility Profile Context

 補充二
