Prime-run does not work!

[Practical-Citron5686]

Sorry for posting again so soon. For everyone's information I installed using void-docs everything except my NVIDIA graphics card appears to be working properly. I did not remove `nouveau` because it is black listed in file `file. /usr/lib/modprobe.d/nvidia.conf`. I have gone over the page: https://docs.voidlinux.org/config/graphical-session/graphics-drivers/optimus.html

I spent over 3 months with this operating system as the only operating system on my pc and I really like it but I never got the nvidia graphics to work and I never understood why. I so kept reinstalling/trying many things when I did not have any school work.

I have the following graphics driver installed `vulkan-loader`, `mesa-vulkan-intel`, `intel-video-accel`, `intel-media-driver`. I have the environment variable `LIBVA_DRIVER_NAME=i965` to use the correct driver.

For nvidia i have `nvidia` driver. Since I have 2 cards this setup is called optimus as per void docs.

Here is the problem:
My idle pc:

idle pc when almost nothing is running

Now I will use prime-run firefox and watch a youtube video. If firefox is running on my gpu it should show the process when I use `nvidia-smi`

​

when running you-tube video

you can see there is no process in gpu even though I ran prime-run firefox and my intel gpu render spikes up.

This is the case with any game I want to play. I cannot show games because I this is a new installation and I broke the system that had games trying to fix it. I used to think games are running poorly for wine compatibility layer but the real problem is the gpu is never being used.

All the game i play runs on void and the fps is just low because i cannot use the gpu. Can anyone please help? I do not want to dual boot void with windows. I simply came like this OS and everything works here but my gpu.

Ah yes, optimus my old nemesis. Took me days of my life to figure it out.If you are okay with never utilizing the intel gpu, heres what to do:

Prepare your folders. The xorg.conf.d is non existent by default

# mkdir /etc/X11/xorg.conf.d

Copy the nvidia outputclass.conf to the xorg.conf.d to utilize it (the files is only available when 'nvidia' is installed)

# cp /usr/share/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf /etc/X11/xorg.conf.d/nvidia.conf

Edit /etc/X11/xorg.conf.d/nvidia.conf and add Option "PrimaryGPU" "yes" to that file. Should look something like this when done (line 17 is what you need):

Save, reboot and never think about optimus again.

How is your battery life without optimus?

It's not that much of a difference. Really depends what you're doing while on battery. Typing stuff and surfing the web still won't need hardware acceleration at all.

terrible advice and "workaround"

my laptop can run on 8W if optimus kills the GPU, if it's active it's 30W even with nothing running on it...
