alternatives to nvidia_drv.so lost during upgrade

[Sebastian Podjasek]

During my update cycle I've lost alternatives to provide nvidia_drv.so. This situation persisted even during distribution upgrade. Forcing nvidia-331 to reinstall fixed this issue - which I mistakenly connected to “ubuntu-drivers-common” package

Log of working X.org after downgrade to 0.2.91.4

Do you have any files in /etc/modprobe.d/ that does not have a .conf extension? If you have, then this could be a duplicate of bug 1376966.

Run the following to check:
ls /etc/modprobe.d/|grep -v '\.conf$'

No, my working and broken configurations both doesn't contain any not
"*.conf" file in modprobe.d directory.
Only difference between them is that working one contains a link:
  nvidia-graphics-drivers.conf ->
/etc/alternatives/x86_64-linux-gnu_nvidia_modconf

Also refering to your bug #1376966, file bumblebee.conf contains
blacklist entry for nvidia.

That is the cause. With the changes in 0.2.91.7 gpu-manager will find the blacklist entries in bumblebee.conf and not load the nvidia module.

However, bumblebee appears to be for supporting laptops with NVIDIA Optimus. From a very quick look at the description disabling the nvidia module seems like it could be by design. Are you using bumblebee?

I've recently upgraded my ubuntu to 14.10 and problem also occurred.

I've removed bumblebee and primus (just remove not purge) and it didn't help.
Downgrading ubuntu-drivers-common to 0.2.91.4 also failed.

But I've found out that my X.org is complaining about missing nvidia module, and indeed there was no such file in /usr/lib/xorg/modules/drivers. Re-installing nvidia-331 did not helped. So I simply copied nvidia_drv.so to drivers and libglx* to /usr/lib and it now works! Although it lacks hardware acceleration but I'm able to finish my work for now.

Maybe somebody will guide me - which package is responsible for linking appropriate nvidia_drv.so to X.org modules?

Forcibly uninstalling & installing of this package seems to fix my missing alternatives to provide nvidia_drv.so
