The screen on my Acer Aspire One netbook (AO722) flickers for a few minutes when Ubuntu awakens the screen after a period of inactivity. I am pretty sure this is not a hardware issue, as I never see this problem in Windows and both of my Acer netbooks exhibit the same problem. I see the flickering in all recent versions of Ubuntu -- 11.10, 11.04, and 10.10. Surprisingly I haven't been able to find a lot of information about this problem online.

I believe the video card in this netbook is Radeon 6290 paired with AMD C-60. I am using the default open source video driver.

Would appreciate any tips on how to get rid of the flicker. Thanks!

Simply installing proprietary fglrx drivers seems to solve the problem.

It is about the same problem you have, but on a Macbook Pro 8,2 with AMD Radeon HD6470M graphics and Natty. I havent tested it myself. But I'm gonna. Have the same card on my ASUS laptop.
