Dear community members,
I have a new model of AORUS 15P RX5L notebook on my desk. The model name is SN21210J001585 with BIOS version FB03 and CPU model 11th Gen Intel(R) Core™ i7-11800H.
I installed Ubuntu 20.04 64bit and upgraded GPU drivers from default to NVIDIA 510.60.02 and CUDA 11.6. Default kernel version was 5.13+.
After a few minutes of doing daily work on this machine I my desktop is freezing. I cannot use mouse or keyboard but was able to connect to it via SSH using second machine. In htop I discovered that Xorg is consuming 100% CPU:
The process name:
/usr/lib/xorg/Xorg vt2 -displayfd 3 -auth /run/user/1000/gdm/Xauthority -background none -noreset -keeptty -verbose 3
I can reproduce that problem using external monitor with HDMI or without it. During the freeze I am not using CPU/GPU so much (I did not launch any AI calculations).
NVIDIA was set up as prime GPU.
$ prime-select query nvidia
Furthermore, I upgraded Linux kernel from 5.13+ to 5.17+ and reinstall NVIDIA drivers but it does not help at all.
Help me to diagnose the root of the problem.
