(一)错误信息:
You appear to be running an X server; please exit X before...
原来,更新驱动需要关闭图形桌面。赶紧查看一下,是不是真的有X:
ps aux | grep X
看到
$ ps aux | grep X
root 2242 1.6 0.0 154212 35820 tty7 Ss+ 04:10 0:01 /usr/lib/xorg/Xorg -core :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
cc 4677 0.0 0.0 11284 1016 pts/8 S+ 04:11 0:00 grep --color=auto X
(二)关闭X的方式有两种:
(1)gdm类型的桌面系统
sudo /etc/init.d/gdm stop
sudo /etc/init.d/gdm status
(2)light类型的桌面系统
sudo /etc/init.d/lightdm stop
sudo /etc/init.d/lightdm status
关闭后,ps看下,的确看不到X了,但是,又有个新的Error:
An NVIDIA kernel module 'nvidia-uvm' appears to already be loaded in your ke...
(三)卸载旧的驱动
#关键的命令:
sudo apt-get purge nvidia-cuda*
sudo apt-get purge nvidia-*
(四)再次安装新驱动,终于OK了!
