I've been annoyed by this same bug and can confirm that the modeset=0 option for the radeon resolved the problem for me. I'm a little surprised that this fix as well as the one from bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/543045 were not fixed for the official 10.04 release.
Fortunately with two radeon options it could be fixed, but I guess usual people who do not often handle module options are going to be lost and much more annoyed than I have been. You just need to add the line: options radeon new_pll=0 modeset=0 in a (for instance) /etc/modprobe.d/radeon.conf file (or any /etc/modprobe.d/ file). -- [RV515] [LENOVO T60] external screen display shows "shivering", horizontal refresh offset https://bugs.launchpad.net/bugs/541501 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
