Ever since updating my Ubuntu 11.04 to 11.10 I experience issues with graphics. The biggest is the "split screen" effect where my desktop is shifted to the right, resulting in having Unity bar in the middle of the screen, as shown here:
This changes from boot to boot, sometimes it's on the left, sometimes in the middle.
What I tried:
- Removing fglrx drivers completely
Installing post-update version of them, but installation is broken ATM in the Ubuntu, so no go.
No one is even trying to fix it (bug report https://bugs.launchpad.net/ubuntu/+source/nvidia-common/+bug/873058 and a couple of duplicates out there)
- Also using the open source "radeon" driver results in the same (I have a better successful boot ratio with this one, proprietary rarely lets me boot)
Other artifacts are:
- serious screen tearing
- weird lines flickering in random places
Did anyone experience that?
- Ubuntu 11.10
- AMD Radeon HD 6950 1GB
