Bbswitch module not found. NVIDIA card will not be powered off #72

Closed sith-on-mars closed 2 years ago

sith-on-mars commented 2 years ago

I'm on the latest freshly installed Tumbleweed KDE 20211016. My bbswitch version is 0.8-11.35 and my suse-prime version is 0.8.2-3.1. It seems the bbswitch module can't be recognised although it's already installed. Here is the output:

/usr/sbin/prime-select get-current
Driver configured: intel
bbswitch module not found. NVIDIA card will not be powered off

Looks like the module cannot be found. Please make sure that also bbswitch-kmp-default package is installed. Then check what 'modinfo bbswitch' tells you.

Thank you very much! Bbswitch-kmp-default package is installed already. Here is the output:

Weird. That should never happen.

prime-select.sh [...] function bbcheck {

searching module is better than rpm package because there are other bbswitch providers like dkms-bbswitch

if ! [ $(modinfo bbswitch 2> /dev/null | wc -c) = 0 ]; then
[...]
else
    #should never happen with suse-prime-bbswitch package as bbswitch is a dependency
    echo "bbswitch module not found. NVIDIA card will not be powered off"
fi

[...]

If I put /usr/sbin/prime-select get-current without sudo, it says bbswitch module not found. But if I put it with sudo, or simply just sudo prime-select get-current, the output will be [bbswitch] NVIDIA card is OFF.

In the older suse-prime version, putting /usr/sbin/prime-select get-current without sudo would always get the output [bbswitch] NVIDIA card is OFF.

Thanks. This helps a lot. What we need is a

export PATH=/sbin:/usr/sbin:$PATH

line at the beginning of the prime-select script

sndirsch commented 2 years ago

I made a new release 0.8.4 with that change. Also already submitted for Tumbleweed.
