In my case, even the nvidia driver not found, the system modifies the xorg.conf and start a default X server.
So I use telinit 3 to quit from the X window. Here is what I do:
(follow the instructions and has no problem)
cp -a /dev/nvidia* /etc/udev/devices/
chown root: etc/udev/devices/nvidia*
(modify xorg.conf: delet "Load "dri"" and change "nv" to "nvidia" in Section "Device"
note: the above changes made to xorg.conf will be changed back by the system)
-------------everything looks good till now---------------
(it still shows failur to check nvidia module after type "telinit 5", and back to the X window, log in, the xorg.conf is changed back! and opengl related game can not run. reboot, same problem)
Since I've already reboot after update the new kernel and the nvidia driver is also a new version, I can not try the tips given in your link (sh NVIDIA-Linux-xxx-yyy.run -q --kernel-name=<new kernel> -K -a).
What else can I do? How may I stop the system modify the xorg.conf? Thanks for your suggestions.
