For some reason, my computer running 18.04 LTS, kernel 5.0.0-36 doesn’t show a login screen anymore on booting up – it boots up until it seems to load the desktop and then it doesn’t. It worked fine just yesterday with kernel 5 and the 430.50 drivers, and I’m not quite sure what has changed.
When I set prime-select on intel I am able to login, but then the nvidia drivers aren’t recognised – nvidia-smi gives me the following error: “NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.”
When I set prime-select on nvidia, the startup issue described above occurs. I’ve generated a bug report while prime-select is on nvidia and attached it.
This is the dkms status output:
“nvidia, 430.50, 5.0.0-36-generic, x86_64: installed
virtualbox, 5.2.32, 4.15.0-70-generic, x86_64: installed
virtualbox, 5.2.32, 5.0.0-36-generic, x86_64: installed”
I’ve purged the drivers and installed them again, trying that for several different versions of the drivers (including 390 and 440). I’ve also tried to downgrade to a earlier kernel to no avail. But like I said, it worked fine earlier on kernel 5 and drivers 430.50.
The nouveau drivers do seem to work (but only when I purge the other drivers) but of course don’t give me the performance I need.
Any advice?
