Been running endeavor OS on my MSI delta 15 (all AMD with no nvidia card) with KDE and it switches between integrated and dgpu like it should. However after installing gnome and using it for a bit I noticed that it was always having the dgpu idling. This basically cuts my battery life in half, and making it less than desirable. I could not find much about it online so I’m presuming its some sort of user error. I do use it for gaming a bit so would prefer a solution that does not involve completely killing the dgpu.

    Hello OP, on this kind of system GNOME should use the igpu by default and the dGPU only when an App “launched with dedicated graphics” from the menu, or with DRI_PRIME=1 from the command line. (Also some vulkan game can also select the dgpu)

    If that is not the case this is a bug.

    Are you using x11 or wayland, can you see what is using the dgpu with nvtop ?

      Thank you for your answer. It does not matter if it is X11 or wayland, both have the issue. I have tried to upload an image of nvtop (I think it was done correctly?) and it seems like a mullvad service is using the dgpu for some unknown reason. I have no clue why it is doing this, as it does not on KDE. I do not know how I would force this to use integrated so any help would be appreciated.

        If you launch mullvad from the app icon, try you add to PrefersNonDefaultGPU=true (or false) in mullvad-vpn.desktop (cp /usr/share/applications/mullvad-vpn.desktop ~/.local/share/applications

        If it is autostarted add it in .config/autostart/mullvad-vpn.desktop

        Or add --disable-gpu to the in Exec : Exec="/opt/Mullvad VPN/mullvad-vpn" --disable-gpu %U
