4 years ago Executing tee /proc/acpi/bbswitch <<<OFF and dmesg |tail -1 results in:
[ 9896.545262] bbswitch: disabling discrete graphics
However cat /proc/acpi/bbswitch results in:
0000:01:00.0 ON
so bbswitch has failed to turn nvidia off.
Hi, I am trying to use configure package suse-prime, that uses bbswitch to power on and off my nvidia gpu. However for some reason powering nvidia off is impossible, even with unloaded kernel modules. I have disscussed this issue on suse-prime github, but so far it seems (if I understand it correctly), that the issue is, that bbswitch is having problem with disabling nvidia on my system.
