I am running Ubuntu 13.10 using an AMD/ATI graphics card Gallium 0.4 on AMD RS880.
Since the last kernel update Unity no longer works. When I log in I only get the desktop wallpaper - no unity panel or top panel. Also, if I start an application it will have no frame.
I have tried numerous fixes.
I am using the open source AMD/ATI driver wrapper from xserver-xorg-video-ati. I cannot use fglrx at all (I have tried on numerous occasions but my laptop will only boot into the low-res graphics version).
I have checked ccsm and the unity plugin is checked.
I have come across numerous fixes on the web but none have worked. These including reinstalling unity, ubuntu-desktop, compiz, as well as reseting them all.
I am currently logged in using Gnome, which works fine, but I would like to have Unity back. It only stopped working on the last update. I have tried booting to the previous kernel but that does not work.
Any help warmly appreciated.
