Also your kernel log shows repeated crashes in the Nvidia driver: WARNING: CPU: 10 PID: 2860 at /var/lib/dkms/nvidia/470.63.01/build/nvidia-drm/nvidia-drm-drv.c:574 nv_drm_master_set+0x27/0x30 [nvidia_drm]
I would recommend trying uninstalling the Nvidia driver for a brief while to see if the problems go away. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1944667 Title: High CPU usage in Xorg with NVIDIA reverse prime external monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-470/+bug/1944667/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
