Comment 57 for bug 532436

I am still having this problem with the latest nvidia drivers.

At nearly every boot nvidia fails to load and gdm tries to run a failsafe xsession.

Unfortunately, there's nothing of importance in either the xorg or kernel logs. The kernel log has no mention of any failure at all and xorg's log just says nvidia failed to load and I should contact support and read my kernel log....

If I exit to terminal, i can start gdm with either "sudo gdm" or "sudo service gdm start" and everything runs normally.

Could this be a mistake in user/group permissions?

Perhaps gdm is being started by a system account that has somehow lost permission to load nvidia.
