I have read the answers on the same question, but I couldn't find the answer. I have installed complete new Ubuntu 14.04.4 LTS on my Sony Vaio, but I can't log in. I have try with different passwords - log and shorts - but it always comes back to the log in screen. To be possible to check some things I had to add my user and pass - after pressing Ctrl+Alt+F1 - and it works. But when I try to log in is writing not my user, but my name - maybe this is the problem. How can I change it?

I have try to check ownership for some files - stays my name on the side. I have move the cache - the same.

Some other ideas?

The type of the laptop is Sony Vaio VPCEB4J1E

This is possibly due to compiz not able to use your 3d card driver. Without any details (Vaio model etc.) It is hard to diagnose.

Solution is to install xfce4-desktop and switch session from lightdm.login screen. But it is a dirty temporray hack just to be able to run X.

  • Now it gets better. In (http://ubuntuforums.org/showthread.php?t=2228404) we have a thread that explains what is happening. As I thought Unity (better say Compiz) is not compitable with your card =) I would say it is a pain in the ... you know... and my recommendation is to avoid Compiz at all. Sadly, the only way now is to use Xubuntu, as gnome-backports are now deprecated and pout of support. – Kaim Apr 02 '16 at 21:24

First you have to install proper driver. Procedure is described here

Then check my comments as there are issued with Ubuntu compiz and ATI as a GPU in Sony systems.
