problem with NVIDIA graphic card driver


I have a NVIDIA GeForce G210M graphic card in a laptop XPS 13. I installed the recent beta driver


su -c ‘sh’

su -c ‘init 5 && exit’

but when I run the nvidia-xconfig and reboot, the windows did not start. The file /var/log/Xorg.0.log showed the following error

Primary Device is:
No devices detected

Fatal server error:
no screens found

Do you know what is the problem? The installation seemed to be ok.

Rename /etc/X11/xorg.conf, it’s obsolete and probably conflicting with autodetection and -configuration.
su -c ‘init 3’
su -c ‘mv /etc/X11/xorg.conf /etc/X11/xorg.conf.obsolete’
su -c ‘init 5 && exit’

If driver installed OK, this should work.
