Title:
Trusty/HybridGraphics: nvidia not detected, prime-switch segfaulting
since introduced.
Status in xorg package in Ubuntu:
Expired
Bug description:
I had a working system a month ago, with a lucky xorg.conf that allowed the
unity desktop to use gdm as window manager, and the mini-displayport to work
(wired to the nvidia card).
I hadn't updated for a month (mid-August 2014), because it was a production
system, and then on 28 Sep 2014, after a full update and restart, gdm only
worked on the built-in screen again, only with the intel card. Nvidia-settings
suddenly is much smaller, and has a switch option, that does not work (gives an
empty warning box as response, if I try to switch to nvidia from intel).
- The result of prime-switch nvidia is "Segmentation fault",
- The gpu manager log says "Has nvidia? no",
- Xorg.0.log says "Failed to load module "nvidia" (module does not exist, 0)"
- sudo modprobe nvidia finishes without error, only, because I added
the line "alias nvidia nvidia-331" to /etc/modprobe.d/nvidia-
331_hybrid.conf
- The command: sudo prime-select nvidia results in:
Error: alternatives are not set up properly
Error: nvidia mode can't be enabled
- lspci output:
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor
Integrated Graphics Controller (rev 06) (prog-if 00 [VGA controller])
01:00.0 VGA compatible controller: NVIDIA Corporation GK106M [GeForce GTX
770M] (rev a1) (prog-if 00 [VGA controller])
- the xorg.conf is constantly deleted, which is annoying, I had a nice
working version earlier
- the best kernel option, that used to work was nvidia.modeset=1, I tried
nomodeset and nothing, but none of them help
I'd appreciate some help here, even if it's a revert (when was
gpumanager introduced?), I just need to continue work as quickly as
possible.
Thanks,
Best,
Aron
