Ubuntu 10.04 randomly won't start X automatically

Asked by Daniel Dewey

When I first installed Ubuntu 10.04 I set up three logins. It would automatically load a graphical login screen and everything worked great, but after some automatic updates about 75% of the time it no longer loads a graphical login screen instead I get a terminal login screen and have to type startx to get into gnome after that it works as expected except I don't get the panel item to switch users and shut down my computer. The odd thing is that this problem doesn't happen all the time.

When the X server runs ok run:

dmesg > ~/Desktop/good.txt; cat /var/log/Xorg.0.log >> ~/Desktop/bad.txt

next time it is bad and still in the terminal run:

dmesg > ~/Desktop/bad.txt; cat /var/log/Xorg.0.log >> ~/Desktop/bad.txt

Then compare the 2 files.

      Shouldn't the first file be ~/Desktop/good.txt? You gave them both the same name, actionparsnip... he's going to overwrite the 'good' file with the 'bad' file.

Yeah my bad, pun intended :)

You get the idea. Once you have both text files you can compare and see why it failed.

This is where the bad log differs. It seems it is a problem with my graphics driver or something related to it. I'm really not sure how to resolve this issue. I do know that I never had this problem with Ubuntu 9.04 on the same machine.

It seems to load fine if I uninstall the Nvidia Driver. I tried installing an older version of the driver, but it does the same thing. I used these drivers with the previous version of Ubuntu without any issues like these.

After desperately trying several suggestions found on other sites I found this article :

http://www.ubuntugeek.com/howto-install-nvidia-drivers-manually-on-ubuntu-10-04-lucid-lynx.html

and I downloaded the correct driver for my card from the Nvidia website. I have the GeForce 6150 card so I downloaded the 64 bit driver for the GeForce 6 series which is version number 256.35 which is completely different from those that come listed after install. After downloading the driver I uninstalled all the video drivers that were on my system and installed the new drivers according to the above guides instructions. So far it seems to have fixed the problem.
