Thank you for following through with this. I am changing the package from xserver-xorg-driver-ati to xorg because of the autodetect problem. It seems strange that it only goes out of range some of the time - I originally classified the bug under the driver because of this, but it does seem to be a problem with xorg not working with your monitor correctly after all.
I will mark this bug as Triaged with High priority so a developer can start working on it. Please post one last thing to the bug report, the output of apt-cache policy xorg ** Changed in: xorg (Ubuntu) Sourcepackagename: xserver-xorg-driver-ati => xorg Importance: Undecided => High Status: Incomplete => Triaged -- Intermittent "out of range" error, Radeon https://bugs.launchpad.net/bugs/248430 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
