Those figures are wrong . This is my issue: I log in and get dual display with laptop monitor at 1440x900 and external monitor on displayport at 1920x1080. Then I open the display settings and turn off the internal monitor and click "Apply". Then both screen turn blank. For some reason there is no timeout so the screens remain blank forever. Hitting Ctrl+Alt+F1 and such does not change anything. I simply have to force poweroff.
I'm able to successfully turn off the external monitor, though. When I turn off the external monitor, I do get the timeout dialog. Maybe the timeout dialog appears in the first case also, but I can't see it and it doesn't restore after the timeout. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/828623 Title: [Regression] gnome control centre does not allow you to disable the laptop screen while leaving an external DisplayPort connected screen working Status in GNOME Control Center: Incomplete Status in “gnome-control-center” package in Ubuntu: Triaged Status in “gnome-control-center” source package in Oneiric: Triaged Status in Fedora: Unknown Bug description: Lenovo T500 with displayport has a 1920x1200 monitor attached, I use the displayport in a similar way to a docking station in that I attach the monitor with a displayport to dvi cable, and then expect to be able to switch off the laptops internal display, only leaving the external monitor working. Screen detection works fine, mirrored screen works fine, but disabling the internal display and activating the external display just leads to the screen going black until the timeout has been reached, whereupon it reverts to its previous setting.
