… due some login problems. I just remove and reinstalled unity-greeter successfully, but now I cannot login in graphic mode with the default user I already had. Does anyone knows why is this happening or what can I do to fix this? A workaround in the web I found that changing the autologin-user=mylocaluser in 50-unity-greeter.conf it would solve this issue but nothing worked.
In terminal mode (Ctrl+Alt+F1) I can change users passwords but still I cannot login in graphic mode.
