The graphics experience is in fallback mode for me. And I checked the settings and it says the graphics driver is Chromium. I am running Ubuntu 11.10 in a virtual box. I didn't like unity much. So reverted from it long back. and it was working fine till now.
How do I fix the issue. No desktop effects is working now!
Note:
Host OS Windows 7
Graphics ATI Radeon HD series
Virtual box version 4.1.6
Another Guest OS Ubuntu Is working fine..
