Unable to switch to Nvidia or Intel appropriately on MicroOS

[sith-on-mars]

I'm using Micro OS Gnome here. I installed the Nvidia G06 driver with suse-prime and bbswitch. I had trouble with switching graphic cards.

According to `prime-select.log', it couldn't detect Intel when I tried to switch to it. Then it would attempt to switch to Nvidia instead and caused black screen with login, because it also couldn't detect Nvidia. Here is the part of the log:

Interestingly, when I switched to Nvidia, suse-prime complained about not able to detect Nvidia and wanted to switch to Intel. This time the Intel just mysteriously worked along with bbswitch.

I think these are MicroOS exclusive issues, as I never encountered them on Tumbleweed. It's similar to one of the old issues here reported two years ago. Switching to Nvidia G05 driver doesn’t help either. Please close the issue if this is an upstream MicroOS issue and can't be solved here.

This looks indeed weird. Honestly I never tried MicroOS - let alone together with suse-prime. Anyway, please check the output of inxi -aG and nvidia-xconfig --query-gpu-info and add it here. Thanks!

Should I install any other packages? I'm sure my Nvidia, suse-prime, and bbswitch are all installed. Here is the output of zypper se --installed-only nvidia.

Thanks. That seems to be the culprit. Please install package nvidia-utils-G06, which includes nvidia-xconfig in the current repository. Meanwhile I've fixed this, but the repositories haven't been updated yet. :-(

From the changelog:

r24 | sndirsch | 2023-01-24 18:26:40 | 9f5e46dbb6ffbe10d756aabe82245b3b | 525.85.05 | 

- moved nvidia-xconfig from nvidia-compute-utils-G06 to
  nvidia-gl-G06

r22 | sndirsch | 2023-01-24 12:33:02 | 06ce482d2b74165715f3a581e23b772a | 525.85.05 | 

- moved nvidia-xconfig to nvidia-compute-utils-G06, since this is
  needed by suse-prime/prime-select to detect nvidia's PCI busid.

Thanks so much for the help! I installed nvidia-utils-G06 and it solved the problem. I was able to switch my graphic cards again yay!!! Interestingly, on Tumbleweed my suse-prime worked flawlessly without nvidia-utils-G06, which is not the case here.

[sith-on-mars]

An off-topic question if you don't mind me asking.

I found in my Tumbleweed installation, I was able to use the Nvidia card on Wayland. In MicroOS, I could only use Xorg when I switched to Nvidia. Do you have any idea why things work differently here? I think Nvidia G06 should be able to work on Gnome.

[sndirsch]

Ok. Thanks for the update. I think on Tumbleweed you used the driver packages before and the update installed nvidia-utils-G06 in addition. It's defined that way for an update.

[sndirsch]

I don't know how things are supposed to work with Wayland with an Intel/nVidia combination. suse-prime only covers an Xorg setup. I haven't tried yet, let alone had it working ... congratulation if it works for you in TW!

[sndirsch]

Anyway ... closing.

[sith-on-mars]

On Tumbleweed the update used to recommend nvidia-utils-G06 until recently. Now nvidia-utils-G06 is no longer recommended when you install Nvida package.

I don't think this changed.
