From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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
Thank you so much, adding --disable-gpu to /opt/Mullvad VPN/mullvad-vpn solved it. Thank you for your time
It would be nice if you edit your post to include what caused the issue, how you identified it and how you solved it, so others with the same issue can easily find an answer and so people who want to help you know that you already found a solution
You can disable the dGPU in the BIOS if I am not wrong. You can also check powertop optimisations to try to extend the battery life of your laptop and change the charging curve of your battery to extend its lifespan.
That’s sort of nuclear. OP wants it to behave like KDE, where the DE prefers the integrated GPU and just select applications wake the discrete one.
You need optimus or bumblebee to do that. Just beware those are pain to install.
optimus/bumblebee is NVIDIA only, with AMD only setup everything should work ootb except some specific bugs (looking at you rocm)
