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.

Is there a way to stop gnome from using dGPU? (self.linux)

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.

Edit: the issue turned out to be a mullvad service using the dgpu. This was found by looking in nvtop and checking what process is using GPU 0, and resolved by going to /opt/Mullvad VPN/mullvad-vpn and adding --disable-gpu.

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.
