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.

Background story: I recently bought a computer with AMD 7000 series CPU and GPU.

amdgpu_top reports 15 ~ 20 watts in normal desktop usage, but as soon as I have video playing in VLC, it goes to 45 watts constantly which is undesirable behavior especially in summer. (I hope that is just reporting issue... but my computer is hot)

When I do DRI_PRIME=1 vlc and then play videos, amdgpu_top doesn't report the power surge. (I have iGPU enabled)

Is there anything more convenient then modifying individual .desktop files? KDE malfunctions when I put export DRI_PRIME=1 in .xprofile so that's a no go.


Solved: removing mesa related hardware acceleration package makes VLC fall back to libplacebo which doesn't do these weird things.

Maybe you could override the Video Acceleration driver instead?
LIBVA_DRIVER_NAME

Hardware Video Acceleration

I don't think that would work since both GPUs are AMD and use the same driver

Oh yeah, I missed that :/
