bbswitch is installed but seems broken. Cannot get NVIDIA power status

[sith-on-mars]

After the latest 20210904 upgrade which updates the kernel to 5.14, bbswitch which I use to power off Nvidia seems to stop working. Here is the output:

/usr/sbin/prime-select get-current
Driver configured: intel
[bbswitch] bbswitch is installed but seems broken. Cannot get NVIDIA power status

Should I just wait for another kernel update to fix it?

Looks like there is no bbswitch kmp package for 5.14 yet, thus no module.

[sith-on-mars]

Thanks! Does that mean we need to wait until Nvidia provides the kmp package for 5.14 first so that bbswitch kmp package can be updated to 5.14 as well?

[bubbleguuum]

No, we need to wait for that package to appear in Tumbleweed. Not sure why it is not already there in the first place.

Specifically, there's a problem building some kmp packages currently due to an rpmlint error:

I have this issue in Leap 15.3 as well:

/usr/sbin/prime-select get-current
Driver configured: intel
grep: /proc/acpi/bbswitch: No such file or directory
grep: /proc/acpi/bbswitch: No such file or directory
bbswitch is installed but seems broken. Cannot get NVIDIA power status

Edit: I commented out blacklist bbswitch in modprobe.d/09-nvidia-modprobe-bbswitch-G04.conf and it seems that the problem solved:

/usr/sbin/prime-select get-current
Driver configured: intel
[bbswitch] NVIDIA card is OFF

Why does bbswitch must be blacklisted?

[sith-on-mars]

Not quite about the Leap issue. On my Tumbleweed the issue is fixed in the 20210906 snapshot.

It is my understanding that it has been a Tumbleweed-only issue.

Closing as fixed.
