Ok, I have 4 computers all running Ubuntu 12.04 with Gnome Shell. on all computers when ever I play games in wine I set wine to run in a virtual desktop. On the first 3 computers I can use things like "Alt-Tab" and I can use the "Super/Windows" key to get into overview mode while playing games and it functions absolutely flawless, I can even move the game to another deaktop and continue playing. However on the 4th Computer neither "Alt-Tab" or "Super" Do anything, as a matter of fact if I hit them more than once the window will loose focus and I have to shutdown to get out of the game. I also noticed on the 4th computer that the Volume popup for Gnome Shell doesnt diplay either, but it does on the other 3. All 4 Computers are running Ubuntu 12.04 (fully up-to-date), and they are all running Gnome Shell (Fully up-to-date from the offical Gnome 3 PPA). All Computers have thier respective proriatary graphics drivers installed. 1st: Works Fine AMD CPU AMD Radeon HD6850 2nd: Works Fine AMD CPU (mobile) AMD Radeon HD 6520G 3rd: Works Fine Intel CPU Nvidia GeForce GTS 250 4th: Doesnt Work AMD CPU ATI Radeon HD4850
