On the X.Org X server - Nouveau display driver automatic login does work, but as soon as i use nvidia 435, 430 or 390 i get stuck with a login screen that wont log me in.
I've had no issues that resembles this on ubuntu 19.04.
It's not that big of deal (having to enter my password i mean), but if there is something i can do to solve this i would love to be in the know.
Update: So i decided to connect the tv directly to the pc the resolution was reset to full hd and now i couldn't enter the desktop even without automatic login disabled. So i entered recovery mode > followed by the resume normal boot procedure and now i could get back in, so i tried automatic login again, and yeah, no go on entering my desktop, so back to recovery mode and the resume normal boot procedure... To my surprise i was treated to an automatic login, but i didn't last, because when i rebooted there was the same problem again.
Thanks for reading.
