Public bug reported:

Binary package hint: xserver-xorg-video-intel

I have a Dell Latitude E6400 with docking station on a Dell 2408WFP
monitor. This used to be connected via Display Port "DP1"  in Ubuntu
Karmic and worked to use the monitor's preferred 1920x1200 16:10 mode.

After upgrade to Lucid, the DP1 connection no longer works. The monitor
is detected properly, listed in display-settings or xrandr -q, but
enabling it via display-settings or xrandr --output DP1 --preferred (or
xrandr --output DP1 --auto) does not wake the monitor from energy save,
it remains off.

Workaround: connect monitor to DVI port (listed as HDMI2 in xrandr) and
configure that.
