I too am experiencing this bug, and I too am using the open source radeon driver (xserver-xorg-video- radeon-1:6.9.0+git20081003.f9826a56-0ubuntu2 from Intrepid, although it was also broken in Hardy). Sometimes the second monitor is at the proper resolution (1680x1050) and position (to the right of my laptop screen and shifted up a bit). Other times it's stuck at 1280x1024, mirroring the laptop display (1400x1050) no matter what I do with xrandr or gnome-display-properties. Even when the second monitor is not displaying what it should, 'xrandr -q' says that the desired resolutions and positions have been applied.
Usually a reboot will fix it. Killing X (Ctrl-Alt-Backspace) never fixes it. Trying to switch to another VT always fixes it. (Oddly, when it's not working, Ctrl-Alt-F1 doesn't switch to VT #1 -- it just corrects itself and stays at VT #7. If I try to switch to VT #1 when the displays are at their correct resolutions and positions, it switches -- and switches back -- properly.) -- External monitor resolution can't be changed on laptop (ati driver) https://bugs.launchpad.net/bugs/227520 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
