Cannot turn Nvidia GPU off

[felikskiszkurno]

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.

Link to suse-prime issue:
openSUSE/SUSEPrime#50

Xorg version 1.20.7 (I am not sure if this is correct).

I am using driver G04 from openSUSE community repo, it contains driver 390.116.

[felikskiszkurno]

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.

[felikskiszkurno]

I am sorry but I cannot supply the output of get-acpi-info.sh script.
There are some dependencies, that I cannot install
