Re: [SOLVED] Black screen after installing optimus-manager

I was just pointing out the pattern that prime-switch somehow didn't seem to complete during SDDMs exit phase (with similar symptoms)

Did removing the vesa driver have any discernable impact?
Next time you try to switch the mode, after the logout try to run prime-switch from a different VT explicitly.

Also

I dont want PRIME offloading is my option because I want to switch between integrated and dedicated GPUs and do not want to use hybrid graphics.

Is not really an answer ("I don't want it because I don't want it") - are you dreaming about much longer battery runtime or stuff?

Edit: english…

Re: [SOLVED] Black screen after installing optimus-manager

I made a typo in that message smile
I meant "I dont think PRIME offloading is my option because..."

I know that there is an option to run programs that require dedicated GPU with prime-run, but at the end I just want to enable and disable nvidia GPU with a press of a button, because most of the time I don't use programs like this. But, when I do, I want them to automaticly start with the only available GPU. For instance, I'm having trouble launching Steam games from console.
Anyways, I just think that this is more comfortable this way.

So, back to the topic, I switched to nvidia and then to integrated mode back. A black screen occured so I switched to another virtual terminal, typed sudo prime-switch and here's the output:

Re: [SOLVED] Black screen after installing optimus-manager

Well, it apparently fails to unload modules.
1. Did the explicit call lead to an effective switch?
2. What's the output of "lsmod" before and after that explicit call?


I want them to automaticly start with the only available GPU

So instead of altering their invocation (eg. by shadowing the binary w/ a script in /usr/local/bin) you click around to switch the GPU, log out and back in to apply that change and then "automatically" start the program on the GPU…?

Re: [SOLVED] Black screen after installing optimus-manager

I'm sorry, but what do you mean by 'explict call'? Running 'prime-switch' directly ?

Re: [SOLVED] Black screen after installing optimus-manager

Initial mode: Integrated.
Explict call did not led to switch, even avter logging out and back in

Re: [SOLVED] Black screen after installing optimus-manager

lsmod before prime-run

?

At no point nvidia_drm or nvidia_modeset seem to be loaded?
https://wiki.archlinux.org/title/NVIDIA … de_setting and check whether they are during the X11 session on nvidia.

Re: [SOLVED] Black screen after installing optimus-manager

That seems to have not been an issue anyway.

Theses here

nvidia_drm             73728  41
nvidia_modeset       1503232  77 nvidia_drm

are the interesting modules and the previously linked "nvidia_drm.modeset=1" would have been the relevant parameter…

Is the lsmod output before or after enabling drm?
If you just enabled the latter, the only interesting question is whether you can now switch back.

Btw. when you ran prime-switch directly, was that while there was any running X11 server (ie. from with a plasma session or while the SDDM greeter was up)?
Cause that'd have been pointless.

Re: [SOLVED] Black screen after installing optimus-manager

Just to recap: I can switch to nvidia mode with optimus-manager without a problem, but when I try to switch back I just get black screen. Restarting sddm doesn't fix the issue.
However, I made an interesting discovery.

Yes, I did prime-switch from GUI, didn't know I had to do it in VT. But when I try to do prime-run in VT and do sudo systemctl restart sddm, I have nvidia (not nvidia_drm or others) module loaded in my lsmod

Re: [SOLVED] Black screen after installing optimus-manager

You first need to "sudo systemctl stop sddm" before you "sudo prime-switch" and then "sudo systemctl start sddm" to make this a meaningful test.

Re: [SOLVED] Black screen after installing optimus-manager

Same behaviour, I did "sudo systemctl stop sddm", then prime-switch gave me no output, then "sudo systemctl start sddm", and logged in. lsmod gives the same output (only "nvidia" module is loaded), but glxinfo says that integrated graphics are used

Re: [SOLVED] Black screen after installing optimus-manager

The important part is that the switch now works what means that the SDDM hook failing is the main cause.
The hook is provided by optimus-manager, so you should raise a bug there. I guess it expects to unload the nvidia driver while that's still (or again) in use by SDDM and aborts because of the failure instead of eg. scheduling the removal.

Re: [SOLVED] Black screen after installing optimus-manager

Switching to LightDM solved this issue. Thank you, seth and V1del, everything works fine now.

So what we did basically:
1) Installed bbswitch package
2) Manually provided BusID options to /etc/optimus-manager/xorg/nvidia-mode/nvidia-gpu.conf and /etc/optimus-manager/xorg/integrated-mode/integrated-gpu.conf according to "lspci | grep -e VGA -e 3D" output
3) Changed display manager to LightDM

Thanks again, have a good day!
