Recently upgraded from 10.10 to 11.10 and am very happy with Unity. However, just in the last couple of days, I find my left launcher and top taskbars changing to a weird YELLOW COLOR after a few minutes of use. The buttons are basically gone, yet if I hover over them I get what looks like the ilnfo bubble. Clicking on that will brilng up what was on that button. I just have to try to REMEMBER what was written on that particular button. If I go to the very extreme RIGHT on the top bar and click I get the 'shut down' drop down. Then I get the little window asking if I want to continue and again if I click the lower right it does shut down.
Anyone else ever experience anything like this? I changed the video card because I the download screen said I needed better hardware to use Unity. Afteer that everything looks greeat, except for this 'yellow' thingy.I 'Blundered' into the answer....Somehow the NVidia DRIVERS didn't install correctly and therefore after a short time I had 'issues'.
Have re-installed 11.10 and for 3 days now I've had no problem.I'm glad to hear that you got that sorted out.
