This is still occurring. Here are some more things I've tried to clear it.
Sometimes it seems that I can remove the corruption by changing the display resolution to something extremely low, but I haven't been able to get that to work reliably. I've tried rerunning my dock/undock scripts. I've tried kwin --replace, and even a different window manager. I've tried changing the refresh rates. The only thing that reliably fixes it is logging out and back in. Of course if I reboot, or restart Xorg from the KDM login screen, xorg comes up in "clone" mode instead of with the DVI display "left of" the LVDS. This corruption occurs every time I run the above described xrandr commands, but I can't capture the corruption via a screen grab tool. -- video corruption after xrandr https://bugs.launchpad.net/bugs/583005 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
