I have a Vaio VCPEB1E0E with the broken screen so I have it on an external screen. I just installed Ubuntu 14.04 and added some other programs that I need (Inkscape, Gimp,...). After that I tried suspending it at it just freezed. So I turned it off manually and tried to turn it on. I get up to the login screen, where I enter my password, butt after that it freezes. It stucks like that for couple of minutes, then black screen with mouse pointer, then login screen again. Retype my password and it stays like that (freeze). I have no idea what to do, because I can only operate through the external screen (all this time the primary screen is on).
Update: After couple of minutes (5) login screen is back and everything goes around and around...
