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.
This is a fully updated oneiric install

A workaround is to run the following commands:
xrandr --size 1920x1200 --output LVDS1 --off --output HDMI1 --mode 1920x1200
compiz --replace
Still, it really should work via the gui...
