I am using a Dell E6410 notebook running Ubuntu. Most of the time I am
running this notebook in a docking station with closed lid and with an
external (DVI) monitor attached to the dock.
Running different kernels I see different behaviour regarding the
display configuration after boot.
Booting a 2.6.32 based kernel the internal display is turned off, the
external display is turned on and running at it's native resolution of
This is what I would expect.
Booting the same system with a drm-intel-next based kernel the internal
display is turned on (although the lid is closed), the external display
is on and shows a resolution of 1024x768.
Logging into X the internal display stays on, the external display
changes resolution to 1920x1200.
I can use gnome-display-properties to turn the internal screen off.
But after each DPMS blanking the internal display is turned on again. :(
Is this some expected behaviour or should this be considered a bug?
Thanks in advance.
