Hello, I see a constant 30% CPU usage in this particular xorg process: /usr/lib/xorg/Xorg vt2 -displayfd 3 -auth /run/user/1000/gdm/Xauthority -nolisten tcp -background none -noreset -keeptty -novtswitch -verbose 3 With some perf I have found that most of the time is spent on: - 32,91% 32,65% [v…

I also have the same issue as OP on Manjaro Linux. Hybrid graphis - Intel + Nvidia. Nvidia GeForce GTX 1650 Mobile Running Manjaro Kernel: 5.9.16-1-MANJARO

I have exactly the same problem on Fedora 33 on Lenovo P51 (Intel and Nvidia). Xorg cpu usage is always over 30% . I suspect the periodic Zoom hangs (over 300% cpu usage for a few minutes) are related. Changing the configuration in BIOS from “Hybrid” to “Discrete”(Nvidia only) fixes the problem, b…

I’m experiencing the same problem on a X1 extreme gen 2 running pop os. The CPU load of the same exact process “/usr/lib/xorg/Xorg vt2 -displayfd 3 -auth /run/user/1000/gdm/Xauthority -nolisten tcp -background none -noreset -keeptty -novtswitch -verbose 3” is always very high especially when I conn…

I too have this problem. I need to investigate and characterise it more fully (tomorrow) but in the mean time, is there any further activity on this thread?

I have the same problem in an Acer Predator Helios 300 laptop, with a 1660 gtx gpu. I would also add that when I turn off the laptop display, everything but the mouse becomes super slow in the display connected to the hdmi output.

The same problem on Lenovo Legion 5 Ryzen 4800H GTX1650ti in hybrid graphics mode with external monitor (via HDMI). Ubuntu 21.04, kernel: 5.13.5-051305-generic, nvidia driver: 470.57.02 Happy to help with logs or experiments if required!

Same problem here, not with hybrid graphics but with an actual graphics card (RTX 3080), I have provided an exhaustive list of the troubleshooting steps I took while trying to fix this problem as well as a bug-report log in this thread : Very High Xorg CPU usage using latest Drivers with an RTX 3080 …

i also have this problem running: popos 21.04 nvidia driver 470.57.02 gtx 1070ti (3monitors) i5 8600k

I have 4 monitors with mixed refresh rates running on KDE and used to have high GPU usage plus high usage on one cpu core. The settings I found that seemed to fix it were Allow Flipping in nvidia-settings, and using Option “UseNvKmsCompositionPipeline” “false” in xorg conf. Turning off Allow…

Could this have anything to do with the issue? DisplayLink displays runs at 1FPS when laptop lid is closed. (#1028) · Issues · xorg / xserver · GitLab
