Fresh, working install of Ubuntu 22.04 with autoinstalled 550 drivers didn’t give nvidia-smi output. I replaced gdm3 with lightdm, purged all drivers and reinstalled with ubuntu-drivers autoinstallto get nvidia-smi output working with atleast nomodeset. This is a newer Ryzen AI9HX370 + RTX4060 laptop device.
Prime select nvidia only has tty accessible with nomodeset where the logs are from and black screen of death without nomodeset nvidia-bug-report.log.gz (342.3 KB)
dkms status returns none
Done, I assumed it was autogenerated. It seems like similar behaviour.
In the intel case, it seems like the amdgpu drivers are not loaded at all? Additionally, when switching in the BIOS to d-GPU only display, I can get expected behaviour under prime-select nvidia, driving xorg as well as applications. Interestingly, using this display mode under prime-select on-demand and manually loading the kernel module also gives behaviour that you’d expect. If I understand correctly, this is effectively using the device in reverse prime mode?
Based on the suggestions, I assume I do not have to be editing configs to point to output sinks for nvidia mode like NVIDIA Optimus - ArchWiki?
Without nomodeset I am unable to generate logs, running the script with cron results in logs that are truncated very early at line 55, even with --safe-mode options.
