I am new to Ubuntu. After updating 12.04, HUD background changed to black instead of transparent and can't use Wine and ccc anymore.

Then I tried GNOME but only the wallpaper appeared and can't do anything. I am using ASUS ATI Radeon 3450/512MB graphic card. Before updating Ubuntu, I installed ATI driver from

Could it be the graphic card driver problem? Any help?

I had the same problem, but I had a black icon set installed. So, all I did was change my icons and I was able to see my applications and such. Also you should still be able to select applications or whatever by pressing ALT+F1, that will highlight Unity trigger, then type in the desired application, use your directional button to navigate, and tap down twice, then hit enter. That should open your application.

Tip: If you don't have MyUnity installed, I would suggest installing it. And, Ubuntu Tweak is another great tool to help you tweak HUD settings. If this doesn't help, and it's a graphics card issue, then you'll have to get advise from someone that's knowledgeable on specific hardware.

Thank you for your answer. I was able to use unity HUD and other applications except wine's and ccc. And I installed Ubuntu Tweak but it didn't help me. My only solution was reinstalling ATI driver. And now it is all going well again :). Also, after graphic driver installed, Terminal window background forced to transparent and I can't change it back. that's weired. – HKL Sep 1 '12 at 13:48
