Trying out 6.12.2 (compiled from the sources) just ended locking the system up hard when logging out (back to kdm.)
Nothing changed regarding the ignored "Virtual 2560 1024." However, as pointed out by agd5f @ #radeon; moving the Virtual over to SubSection "Display" fixed the problem (as specified by man xorg.conf.) So the root cause was xrandr disregarding what the driver thought of as the virtual space and went with a default 1280x1024. ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: New => Invalid -- [HD 4650] Radeon multihead with HD 4650 is broken https://bugs.launchpad.net/bugs/357978 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
