Questions about Official EndeavourOS Nvidia Optimus WIKI and nvidia-installer

thank you! this is the program i was using. i read the wiki and it should work now.

If you have it working let me know what you have done. I’m interested in knowing. :slightly_smiling_face:

i was able to install prime-run and follow the wiki:

here is the output from xrandr:

xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x45 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 3 associate
roviders: 0 name:modesetting
Provider 1: id: 0x258 cap: 0x0 crtcs: 0 outputs: 0 associated providers: 0 name:NVIDIA-G0

however, when i ran glxgears, i did not see the overlay onscreen.

i wonder if there is a way to know whether gpu offloading actually happened. Is there another test or system log? Sorry ricklinux regarding my low skill level.

Did you look at this part?

Edit: Do you have mesa-demos installed?

i did now.

still no overlay.

I don’t have any hybrid equipment so it’s hard to understand sometimes what you mean? I have nvidia but on a desktop.

Sorry i’ve not been clear.

The wiki describes that with the commands given, there should be a text overlay in the glxgears to indicate that the output is indeed being processed by the nvidia gpu.

I see output similar to yours, but no text overlay, so i am not sure whether it is being generated by the gpu or not.

i wondered if there is any command or log that shows what gpu is being used by a particular task.

just to make sure that my installation is working as hybrid.

Did you use the command to put it in hybrid mode?

Edit: Read the section under this.

How can I check which GPU my X session is running on ?

Run optimus-manager --print-mode. Alternatively, you can run glxinfo | grep "OpenGL renderer" to get the name of the current GPU.

I was directed to a log file created by optimus-manager during switch.

here is the output:

less /var/log/optimus-manager/switch/switch-20201017T200030.log

i suppose it was successfully set up then.

thanks.

Well it looks good to me. Like i say i don’t have any of this hardware to play with so i’m just going on gut instinct of how it is supposed to work. Following what i know and guessing at the parts i don’t. This looks right and i don’t see any errors.
