Thanks for all your input @ricklinux ! Really appreciate it.
OK, I don’t recall making a specific choice about the display manager when choosing XFCE. What are you using instead of lightdm?
I changed the config to say
But it did not change the behavior. I also read on the discovery page for lightdm you provided that not having set this would cause the screen to stay black before the login screen even comes. But that’s not the case. I see the desktop with the login screen. It’s just that after entering the password to login the screen goes black and stays like that (no Signal is sent to the monitor anymore).
So I then retried ‘sudo nvidia-installer-dkms -n’ route, since in that case I didn’t even get a login screen. But this didn’t change that either.
I do not recall setting the kernel parameters you listed. Can one or multiple of them cause the nouveau driver not working properly (getting the blinking cursor in the top left screen instead of a login screen)?
Are you suggesting to remove these somehow?
Edit: am I in the wrong group here? Should I rather post my issue in a lightdm group in the forum?
