Running Hardy Alpha 5 with latest updates.
I am still seeing this bug or so I think...
Here is my setup : A laptop in its dock with an external monitor plugged on the DVI port of the dock. The "native" resolution of my monitor is 1280x1024@60hz
But in fact, I only get 1152x864@75Hz (I can change it using the Gnome RANDR applet for example).
Here is the output of xresprobe :
$ sudo xresprobe intel
id:
res: 1280x800

xresprobe doesn't seem to see the DVI monitor.

Here is the output of ddcprobe (seems fine) :
$ sudo ddcprobe

I have also attached my Xorg.0.log

PS : If the external monitor is plugged on the VGA port, it works like expected.
