It sounds like gdm is getting confused by the Virtual keyword in xorg.conf.
IIRC, Virtual was added to support xrandr. Two things need to be researched: A. What this parameter enables. B. Why gdm is getting confused by it. Also, I suspect there are a number of dupes of this bug (like 139912 possibly) that should be duped together with this one. ** Changed in: xorg (Ubuntu) Sourcepackagename: None => xorg Importance: Undecided => High Status: New => Triaged -- gdm uses incorrect screen resolution https://bugs.launchpad.net/bugs/146828 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
