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-X, which is subscribed to xserver-xorg-video-amdgpu in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
