I am facing a strange problem out of nowhere. I turned off the PC fine with latest Nvidia proprietary drivers installed yesterday. Booting this morning, I noticed that one of my two monitors was not working and noticed these error messages on reboot
[ 7.348261] kernel: [drm:nv_drm_load [nvidia_drm]] ERROR [nvidia-drm] [GPU ID 0x00000800] Failed to allocate NvKmsKapiDevice
[ 7.348371] kernel: [drm:nv_drm_probe_devices [nvidia_drm]] ERROR [nvidia-drm] [GPU ID 0x00000800] Failed to register device
Thinking some driver crash, I uninstalled proprietary driver using TTY and installed default driver but I am still seeing same DRM error on boot. I am unable to install proper drivers (all Nvidia drivers are grayed out in Ubuntu software “additional drivers”) so unable to use my dual monitor setup. I have a dual boot setup with Windows and it works fine with Windows. I have disabled Virtualization in BIOS, no effect.
The system is unstable as well. Sometimes after login, I get a black screen but the PC is working in the background because I hit the correct keyboard shortcuts, I'm able to shutdown the PC. Sometimes it won't go black and work flawlessly (it has been working with one monitor for last 12hrs)
uname -r
outputs 5.15.0-52-generic
Any help will be greatly appreciated.
Thanks
Update: I went ahead and using TTY I installed the nvidia-driver-515-server
drivers. I have not restart the PC since though. How do I troubleshoot this issue
