Ubuntu - GPU - AMD GPU - Modules - Restart a failed amdgpu kernel module

If the video card crashes, an option is to just restart the graphics modules.

Restart the graphics modules

sudo cat /sys/kernel/debug/dri/N/amdgpu_gpu_recover

Another approach to restart the graphics modules

Start your system with amdgpu.gpu_recovery=1 kernel parameter to automatically reset it on a crash.

NOTE: Using the gpu_recovery kernel parameter, allows you to save your work even if it is not visible, and then reboot.
