Yes, confirmed this works, so your diagnosis looks correct :) I did the following:
1) Set up a spanned laptop + external display configuration. This works, correct? Correct this works fine and the main display works at my full resolution 1900x1200 2) Open up a terminal, and run "xrandr --output LVDS1 --off". This should turn off your laptop panel, leaving only the external display active. It should *also* not break your external display. Correct, this turns off the laptop display, moves all windows onto the main display and the main display stays at full resolution with no problems. 3) Report whether or not (2) turned off your internal display without breaking your external display :) Yes! -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/861426 Title: [Oneiric] [Regression] When disabling onboard LVDS display and just using external VGA screen corruption occurs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/861426/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
