The nvidia driver lives inside the Xorg process so I don't think this is Xorg's fault but is Nvidia's. Particularly since you've said "Disabling the nvidia driver (going back to an opensource driver) removed this spiking".

I'm experiencing some stuttering on my machine after running updates today Mar 18th. The stuttering is for all visual effects including mouse movement, videos playing, dragging windows, animations and more. The stuttering is not affecting sound (as far as I can tell). The stuttering does not seem to happen on any regular interval, but does happen every 500-1000ms lasting for 50-100ms... just enough to be annoying enough to open a bug report :P I think that this issue is related to Xorg and the nvidia drivers doing something, but I'm not sure what exactly could be the issue. Here are some related links that led me to report this bug: - https://unix.stackexchange.com/questions/568173/nvidia-drivers-390-440-stuttering-ubuntu-20-04 - This led me to start thinking that the problem could be with Xorg or nvidia - https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-440/+bug/1867352 - I'm experiencing all of these problems reported (including the Xorg.conf message), but I'm not getting a full freeze, I'm only getting stuttering) Steps I've taken: - Updated my system to latest packages on 20.04 - Installed [kwin-lowlatency](https://github.com/tildearrow/kwin-lowlatency) when I thought it might be related to the compositor - Toggled various compositor and Xorg settings - A few reboots here and there If I'm not including enough information please let me know what else to include and how to report it.
