After attempting to log in, press Ctrl-Alt-F2 and log in. Look at:


Do you see any errors (lines that start with EE)?

Also check /var/log/lightdm/lightdm.log (or the gdm log, if you're on
gdm now) and see if anything there ... but considering you've tried two
different dm's now, I doubt the display manager is the issue.

You could also try a simpler desktop environment. For example, try
installing LXDE or fvwm and see if you can get one of those to start.
