Public bug reported:
I am using Ubuntu 14.04 with an Intel 4000HD and Nvidia GTX 770.
I have noticed that my gpu-manager claims that:
Was nvidia unloaded? yes
even though the nvidia module is loaded and was never unloaded (and lsmod
displays it).
Quick investigation showed that gpu-manager checks whether that module was
unloaded by running:
dmesg | grep -q "nvidia: module"
I assume that the intention was to detect any "nvidia: module unloaded" or
similar messages.
However, my dmesg contains several other messages that match this pattern:
nvidia: module license 'NVIDIA' taints kernel.
nvidia: module verification failed: signature and/or required key missing
- tainting kernel
These messages are not realated to unloading the module, it sucessfully keeps
running afterwards.
Therefore I believe the pattern used by gpu-manager is incorrect.
Possible solution is to correct that search string. The only message that
appears in my dmesg when I unload nvidia module is:
[drm] Module unloaded
The dmesg output never explicitly names `nvidia` when it is unloaded.
Another possible solution would be to grep lsmod instead of dmesg, to check if
the driver is currently loaded.
