Ubuntu 22.04.1 LTS, RTX 3060Ti, Failed to allocate NvKmsKapiDevice


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.

I’m unable to attached is nvidia-bug-report file. It keeps stuck on “Processing upload” step. I will try to attach it in a reply, will post the contents otherwise.

Any help will be greatly appreciated.
