I have prepared a test kernel with an upstream patch that has solved this problem for some models of graphics card.
I would appreciate it if anyone who has the problem could test this kernel and report on whether it solves the problem for you. http://people.canonical.com/~sconklin/radeon_flicker/ The code used to build this kernel is in the "flicker" branch of my public git tree: http://kernel.ubuntu.com/git?p=sconklin/ubuntu- lucid.git;a=shortlog;h=refs/heads/flicker -- [RV530] Video problem: External monitor wavy, unreadable. ati radeon [Needs pll quirk] https://bugs.launchpad.net/bugs/537640 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
