A workaround for now is to disable KMS. sudo echo options radeon modeset=0 > /etc/modprobe.d/radeon-kms.conf

Then reboot. -- [rs690m] Graphics corruption with ati x1200 https://bugs.launchpad.net/bugs/556782 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
