I've seen misbehavior similar to this bug that turned out to have a cause not listed here.
If you have a monitor capable of 20048x1536 resolution, X 7.3 will ignore the high-res modelines it gets from EDID complaining that the vertical size of the mode is too large for the virtual desktop size. This problem is due to a poor choice of default virtual-desktop size and can be fixes with an explicit Virtual declaration; I use "Virtual 2048 1536". -- Xorg resolution falling back to 640x480 and/or 800x600 when h/v freqs incorrect https://bugs.launchpad.net/bugs/3731 You received this bug notification because you are a member of Kubuntu Team, which is a subscriber of a duplicate bug. -- kubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
