X Server won't start after update to nvidia beta driver

[Gibs]

I just had this problem: when I rebooted my computer it would give some errors and present me to the tty terminal. When I tried 'startx' it failed.

I gave a quick look at the /var/log/xorg.0.conf file and it said the nvidia kernel module couldn't be loaded.

I will present here the solution I found in case someone else needs it:

[1]First remove the broken driver by running

sudo apt-get purge nvidia*

sudo rm /etc/X11/xorg.conf

[2]Then reinstall the recommended and stable driver

 sudo apt-get install nvidia-current

[3]Then reboot

sudo reboot

You will have to reinstall the beta driver and try again.
Hope this helps other people. ;)

won't work.. because this will install driver version 295.40 on my ubuntu 12.04lts system

Assuming your drivers were working prior to installing the experimental drivers

sudo apt-get remove nvidia-experimental-304 nvidia-settings-experimental-304

or

sudo apt-get remove nvidia-experimental-310 nvidia-settings-experimental-310

will remove just the experimental drivers.
You can then try reinstalling them with

sudo apt-get install nvidia-experimental-310 nvidia-settings-experimental-310

then rebooting

I'm confused... Do I have to use both, the experimantal AND the nvidia-current at the same time? The additional drivers msnu sais, the experimental driver is activated but not in use. what can I do?

No, you can only use one driver at a time.
In my solution I activated the nvidia-current so that I could resume my desktop interface. From there I had to choose to activate the beta driver again.

Ok, thank you

Did you happen to run nvidia-bug-report.sh or save your kernel log? If the kernel module can't be loaded, there should have been a message there about why not.

No, I did not run nvidia-bug-report.sh but I looked at the log X generated.
It had a lot of info about my computer there and many warnings. I will check later more carefully trying to find more info on the problem.

I'm used to my ATI desktop PC and so my NVidia powered laptop drives me crasy, but this helped me out. Thx
