Ubuntu – Problem graphics with ATI Radeon x1270 (RS690M) on Ubuntu 12.04

atidrivers

I'm Italian and so I apologize for my English!
I'm a beginner to Ubuntu and I tried it on my desktop PC and it's fantastic, fast and fun!

I decided to try it on my netbook Packard Bell DOT M/A and this is the configuration:

  • AMD Athlon L110 1.2GHz
  • 2GB of RAM
  • ATI Radeon x1270 (RS690M)
  • 150GB Hard Disk

I installed Ubuntu 12.04 with Wubi (dualboot Windows 7 + Ubuntu 12.04), because the netbook does not have a DVD player!

During the installation everything is OK, after it was installed I see mistakes in the graphical display!
I see objects that are seen in different colors and moving (buttons, mouse pointer, text bar … etc …)
At one point came not to see anything, such as this screenshot:

The drivers are open, that is already installed in Ubuntu.
Windows 7 video card runs fine, can run well Aero (transparent window effects), I can watch movies in HD and play some games with the Catalyst drivers from AMD.
Now I ask a favor, you can help me solve this problem?
Is there a fix for this driver or drivers different on the Internet?
Thanks for your attention, good bye!

I have a Gateway L3103u Netbook with this exact same card and problem. The only fix I have ever found is by installing fglrx alongside the open source driver. While the card is not supported in the latest versions of Catalyst, the installation of the driver fixes whatever modeset is causing the buffer error (what I call the drawing of all of those lines).

Disabling modeset (with nomodeset) will also disable your ability to scale your framebuffer, but that might not be an issue for you.
