So I installed 19.10 fresh from USB.
I picked no login required.
First reboot after install I'm welcomed inside Ubuntu.
But second time I'm prompted to login for no reason.
Worst part is that i login with right password and all but it just loops me back to the login screen again.
If I enter wrong password, it tells me I'm wrong.
Tried to login via terminal and then type "sudo startx".
That just led me back to login screen.
Please help me, I'm running a first gen amd ryzen and nvidia 980ti.
Edit:
SOLVED! In my answer below.

I had this issue after upgrading from 19.04 to 19.10.
The solution that worked for me is to switch display manager from GDM3 to LightDM.
If you have installed the
lightdm
package, just runsudo dpkg-reconfigure gdm3
and select LightDM.After rebooting you should be able to log in.
I have since found a solution to fix login loop without changing GDM3 to LightDM:
On the login screen, press Ctrl+Alt+F3.
Log in to the shell using your username and password.
Uninstall and reinstall the
gdm3
package:Now just select GDM3, and after a reboot it should work fine.
