When nvidia mode is set in nvidia prime, i am not able to resume from suspend and always get black screen. This is known issue in ubuntu forums and no one has solution for it.
Everyone says use your intel one! but that’s not a solution.
When i switch to console (ALT CNT F1) i am able to resume from suspend but can’t switch to graphical mode (ALT CNT F7).
I investigate the issue a little bit. After resume, bbswitch reports that the nvidia card is OFF. When i try to turn it one by tee /proc/acpi/bbswitch <<<ON, It remains OFF. I got this error in dmesg after : nvidia refused to change power state currently in d3.
I will be happy to help fixing this issue because everytime i have to close everything and shut it down.
Edit : I investigated the issue more. Here are some lines from dmesg: (i got from console)
[ 64.298880] nvidia 0000:03:00.0: Refused to change power state, currently in D3 [ 64.368435] NVRM: GPU at 0000:03:00.0 has fallen off the bus. [ 64.368534] NVRM: A GPU crash dump has been created. If possible, please run NVRM: nvidia-bug-report.sh as root to collect this data before NVRM: the NVIDIA kernel module is unloaded.
I’ve also attached nvidia bug report file below.
Any help would be appreciated.
