I am using an ATI Radeon 7500 as well but on a Gateway Laptop. Last night I downloaded the latest 6.0.6 Dapper desktop CD. It was apparent even in the LiveCD that there was a graphical issue. I installed it and the problems outlined above by others existed.
So that's a completely vanilla install with no config changes or driver updates, or anything. I ran the update and downloaded the 130 updates that were required thinking a fix might be already out there and nothing changed. My problem looks exactly like the screenshot above. -- Garbled using open source Radeon driver https://launchpad.net/bugs/38198 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
