set-startup has no effect

[NerosTie]

When I type sudo optimus-manager --set-startup nvidia then restart my laptop, I run on the Intel GPU.

I use SDDM / ArchLinux / KDE.

Everything looks fine in those logs, your computer is indeed starting in Nvidia mode.

However, I just found out that there's a problem between SDDM and optimus-manager. I would bet that your problem is the same as this other issue : #2

You can try the workarounds I have proposed in this issue while I investigate the problem.

When I set sudo optimus-manager --set-startup nvidia then reboot, I'm on the Intel GPU but bbswitch tells me the Nvidia is ON.

(If I type sudo optimus-manager --set-startup intel, bbswitch tells me it's OFF, in that case, it's ok)

[Askannz]

You mention bbswitch but from the logs you have given, it seems optimus-manager is not configured to use bbswitch. Is it loaded in your system in some other way ? With a file in /etc/modules-load.d/ for instance ?

If that's the case, you should disable that, it's probably causing some conflict. If you really want power switching to be done via bbswitch, set it in the configuration file.

[NerosTie]

Hm, the logs was before I switched to bbswitch. When optimus-manager is set to use Nouveau, bbswitch is completely disabled. But I didn't know how to check if the Nvidia card was ON or OFF with Nouveau...

[Askannz]

But I didn't know how to check if the Nvidia card was ON or OFF with Nouveau...

I actually don't know how to check that. But if nouveau is loaded, it supposedly powers down the card unless an external video output is in use.

So, back to your original issue, you said

When I type sudo optimus-manager --set-startup nvidia then restart my laptop, I run on the Intel GPU.

How do you check that you are running on the Intel GPU ?

[Askannz]

Could you please test the new v0.3 release and see if the problem is still there ?

[NerosTie]

It works! 🎉 I can close this issue. Thanks!
