For me, disabling the KMS (echo options radeon modeset=0 > /etc/modprobe.d/radeon-kms.conf) fixes the main problem, but introduces other problems (ugly boot, black borders around some windows, etc--but these are not in the scope of this bug).
In contrast to #30, I did not have the problem in 9.10--was KMS even an option there? I think it's obvious that moving some code to the kernel has introduced the problem, but we need someone qualified to make a fix. I'm afraid kernel hacking is far out of my comfort zone. I think at this point the bug will remain in Lucid's release. Hopefully after the stress of an upcoming release has passed, someone will be able to take a look. -- [Legacy Radeon cards] Desktop effects/compiz: dim display when zooming https://bugs.launchpad.net/bugs/539163 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
