Title:
Unable to switch back to nvidia after suspend on intel
Status in ubuntu-drivers-common package in Ubuntu:
Triaged
Bug description:
I am not sure that it is something that an issue caused by nvidia-prime
or if it is something that is cause in the drivers or if it is a bug with
the kernel itself, cause it seems to be a problem with Linux PM, so this bug
could be moved if needed
*** What's Wrong? ***
As the title states, I am unable to use the Nvidia GPU when I have
changed profile for intel then computer on suspend for more than 30
minutes ( This has to be determined precisely how long until I get the
issue ) and then set back the profile to nvidia.
So basically, it seems that the nvidia modules are unable to be loaded, I
have tried to fix
the issue using bbswitch. It doesn't work neither, if the
/sys/bus/pci/devices/0000\:01\:00.0/power/control is set to auto, I am unable
to load the kernel modules anymore.
*** What do I expect ***
Well, I was hoping that I would be able to keep my laptop on and simply
switch from one GPU to other
seamlessly. It is, until I put my laptop on suspend for an extended time
while I am on powersaving mode
