I have recently started with installing ubuntu 12.10 (x64) next to my windows 8 (x64) install. But since installing the amd proprietary drivers I got weird black horizontal lines in top of the screen. See the 11sec video I made with my phone to know exactly what I mean: http://youtu.be/OULpUYKPjj0

I had to install the proprietary drivers because with the opensource drivers I couldent login after first restart from fresh installation. I only got a black screen and a mouse.

This are my specs: Gigabyte GA-Z68X-UD3H-B3 (rev. 1.3) AMD radeon hd 6950 Dell UltraSharp U2312HM (connected with DVI)

I currently run the latest beta drivers from amd, but with the stable I had the same problem..

The strange thing is when I boot the computer, I get the black lines. But I found out that when I log out, and log back in, the black lines are gone! This however is not really an ideal situation.

How can I fix this problem to completely get rid of these black lines?

  • I got the same issue, it doesn't occur every time, haven't find out what causes it yet. I think it is simply bug in the drivers and there won't be a simple solution.

  • It looks similar when I have installed "Pardus 2011" on my Machine (Now using Fedora 17). This is very strange. I think it is a driver issue. Feb 15, 2013 at 12:53

Turning on "Tear Free Desktop" (Catalyst Control Center -> Display Options -> Tear Free) seems to make the dashes less frequent.
