Title:
nvidia-331 selected but nouveau loads
Status in “nvidia-graphics-drivers-331” package in Ubuntu:
Confirmed
Status in “xserver-xorg-video-nouveau” package in Ubuntu:
Confirmed
Bug description:
After upgrading to Trusty, I briefly used the nouveau driver to check
whether bug 1243557 still existed; after finding that it did, I
switched back to nvidia-331.
However since then, frequently (>50% but not always), the system loads
nouveau first, then fails to load nvidia-331 because of this:
Apr 30 08:00:29 lap14 kernel: [ 17.789267] nouveau [
DEVICE][0000:01:00.0] BOOT0 : 0x0d9160a1
Apr 30 08:00:29 lap14 kernel: [ 17.789269] nouveau [
DEVICE][0000:01:00.0] Chipset: GF119 (NVD9)
Apr 30 08:00:29 lap14 kernel: [ 17.789271] nouveau [
DEVICE][0000:01:00.0] Family : NVD0
[...]
Apr 30 08:00:32 lap14 kernel: [ 21.574983] NVRM: The NVIDIA probe routine
was not called for 1 device(s).
Apr 30 08:00:32 lap14 kernel: [ 21.574987] NVRM: This can occur when a
driver such as:
Apr 30 08:00:32 lap14 kernel: [ 21.574987] NVRM: nouveau, rivafb, nvidiafb
or rivatv
Apr 30 08:00:32 lap14 kernel: [ 21.574987] NVRM: was loaded and obtained
ownership of the NVIDIA device(s).
WORKAROUND: at a text terminal:
sudo apt-get purge nvidia-331
sudo apt-get install nvidia-331
sudo update-initramfs -u
sudoedit /etc/default/grub
#remove 'splash' from GRUB_CMDLINE_LINUX_DEFAULT, and save with the default
name
sudo update-grub
#reboot the system
