First before I start, I would like to say I already followed the following guide for my AMD Radeon 7850: What is the correct way to install ATI Catalyst Video Drivers (fglrx)?
I am running Ubuntu 13.04 (64bit) and have everything updated. I use Gnome 3 as my GUI. Now when I launch steam it returns the following error (BTW: steam still opens):
OpenGL GLX context is not using direct rendering, which may cause performance problems.
Also when I open activities menu on Gnome 3, the background isn't transparent... It is black, and you can't really see the different workspaces.
any help would be appreciated!
