Use dgpu for the browser

Framework Laptop 16 Linux
1

Hi,

I would like to know how to tell a program to use the dgpu, e.g. this would be good for the browser because roll20 and foundryvtt drive the internal gpu to 100%.

Here is a link for roll20 via chromium, but I have not managed to insert “DRI_PRIME=1” so that it is always executed with the dgpu.

#!/usr/bin/env xdg-open

I use prime-run [command] to launch stuff onto my eGPU, which is just a handy wrapper around DRI_PRIME and some other env variables.

3

so you have create an alias?

No, it’s an nvidia tool. See section 2.2:
https://wiki.archlinux.org/title/PRIME

Have found a solution, adding --env=DRI_PRIME=1

Exec=flatpak 'run' '--env=DRI_PRIME=1' '--command=/app/bin/chromium' 'io.github.ungoogled_software.ungoogled_chromium' '--profile-directory=Default' '--app-id=lfdfkfapnccpcbhkddgibegcbhhbdekf'
