18.04 / login loop / Radeon Xpress 1250 (RS600M) on Samsung R60 plus laptop
I upgraded my 16.04 to 18.04, I see the login screen, can log in and will be immediately logged out.
I know many people have this problem and searched and tried everything: * using lightlm * installed unity desktop * checked for X errors * etc.
No success. I really don't have a clue what's going on or how to even track down what's up.
Is there any workaround for this problem? Any way to track it down?
I suspect that it has to do with the graphics driver. But I didn't install anything special and the graphics card is very old. 16.04 worked... so I'm really wondering how this can happen.

One way I can think of is to install the Oibaf AMD drivers. Since you can't login press Ctrl+Alt+F2 and log in to your account from the TTY. Then run the following lines to install the AMD drivers for Ubuntu 18.04
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo apt upgradeThen reboot
Hope this helps!
