[SOLVED] NVIDIA Driver Causing high CPU Usage on Certain Apps

8bitredstone · 2024-12-14 23:43:41

PROBLEM
Sometime within the 1-2 weeks I started having issues with some programs (discord, terraria, Pixtopix, ...) running at extremely high CPU usage (70-98%), normally 15-20%. Some applications are unaffected, namely Minecraft; which is odd, as it is way more resource intensive than the other applications.

WHAT I TRIED
From what I can tell this is not a kernel issue, as I had the same issue under linux-lts + nvidia-lts, linux-zen + nvidia-dkms, linux + nvidia, and linux + nvidia-open

This also doesn't appear to be a dual monitor issue because
1. I ran linux with an NVIDIA card for 6 months with 2 monitors with zero issues
2. If I keep the NVIDIA driver installed, but remove my xorg settings for the monitor and disconnect the monitor I still have issues

The only fix for this is if I uninstall the NVIDIA driver, so it is clearly an issue with the driver from my perspective

So does anyone know a fix to this? Is anyone else having this issue?

Here some hardware specs to help diagnose:

Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General and the outputs of

[     7.336] (II) IGLX: Loaded and initialized swrast
[     7.337] (II) GLX: Initialized DRISWRAST GL provider for screen 0

Remove xf86-video-intel, report back with the result of that.

Also

failed to load driver: nouveau

What'sthe output of

printenv

as it turns out the entire issue was just being caused by having the "xf86-video-intel" installed

Thank you for your expertise

it weird though that this used to be fine to have installed but now was causing me issues. It also made me have to change my lightdm monitor setup script:
xrandr --output DP1 --off --output DP2 --off --output HDMI1 --off --output HDMI2 --primary --mode 1920x1080 --pos 1920x0 --rotate normal --output HDMI3 --off --output VIRTUAL1 --off --output DVI-D-1-0 --off --output HDMI-1-0 --mode 1920x1080 --pos 0x0 --rotate normal --output DP-1-0 --off --output DP-1-1 --off

xrandr --output DP-1 --off --output HDMI-1 --off --output HDMI-2 --mode 1920x1080 --pos 1920x0 --rotate normal --output HDMI-3 --off --output DP-2 --off --output DVI-D-1-0 --off --output HDMI-1-0 --primary --mode 1920x1080 --pos 0x0 --rotate normal --output DP-1-0 --off --output DP-1-1 --off

either way, at least it's fixed

The output names -unfortunately- depend on the driver.
But fwwi, you don't have to explicitly off anything and there's https://wiki.archlinux.org/title/Multih … _xorg.conf
