I have been using ubuntu 20.04 since release, I started with gdm3 and then I got the infamous login loop error which I couldn't solve without switching to Lightdm. The issue is when I switch to lightdm I am getting prompted for my password for everything. Things like mounting a usb drive, refreshing the system repositories, opening any application which requires root priveledges and even powering off the pc. Also, the unlock button to change user settings is greyed out. None of these actions required authentication when logging in with gdm3.
I also noticed that when I click the shutdown button it says there are two users logged in (both of them under my name). It seems like the only solution I can find is to switch to gdm3 which I would love to do, but I can't even get gdm3 to boot.
for gdm3 I have tried the following solutions:
- Permissions on .Xauthority and .ICEauthority are correct
- /tmp permissions are properly set
- I tried removing .Xauthority and .ICEauthority
- I tried purging and reinstalling gdm3
- startX works from tty3 perfectly fine.
Also it may be helpful to know that I am using manually installed nvidia drivers.
If anyone has any solutions to either of these problems it would be very much appreciated.
