Frozen screen randomly ubuntu 22.04, Linux 5.15, Nvidia driver 515.86.01

Hi all,

I’m experiencing random frozen screen in my system with :

  • Ubuntu 22.04
  • Kernel 5.15.0-47-generic
  • Nvidia driver 515.86.01

Moreover, I see the following errors in my dmesg:
[ 18.293664] [drm:nv_drm_master_set [nvidia_drm]] ERROR [nvidia-drm] [GPU ID 0x00000100] Failed to grab modeset ownership

Thank you!

You’re getting an Xid 79, fallen off the bus. Most common reasons are overheating or lack of power. Please monitor temperatures, reseat power connectors/the card in its slot, check/replace PSU.
