Bug Description
Binary package hint: xserver-
When plugging in an HDMI display dmesg prints
[drm:drm_
xrandr still says VGA1, HDMI1, DP1 disconnected. No other method detects the display, not even rebooting with the display plugged in changes anything.
on 2.6.35-
This is an Dell XPS L501X notebook with nVidia Optimus and i5 CPU with built-in GPU (Optimus doesn't work, nvidia drivers not installed, empty xorg.conf, autoloads i915)
It's an DVI display with HDMI adapter cable, everything works as expected when the machine runs Windows (with both nVidia and Intel GPUs).

Same behaviour with mainline kernel drm-intel-next 2.6.38-997-generic, except there aren't any more messages in dmesg.
