Hello,

Did anyone manage to get the DisplayPort output working? The T500
(2082-6PG) sports the following ("switchable graphics"):

00:02.0 Intel Corporation Mobile 4 Series Chipset Integrated Graphics
Controller (rev 07) 

01:00.0 ATI Technologies Inc Mobility Radeon HD 3650

I'm using a Delock DP->HDMI adapter. I'm running 2.6.31-rc8 and xorg
1.6.3.

With the Intel (driver 2.8.1) using KMS (modeset 1 for i915), I get "DP1
disconnected" in xrandr. Without KMS the DP output doesn't even show up
in xrandr.

With the Radeon (driver 1.2.5-1 from Debian Sid and "Discrete
graphics" in the BIOS) I get "DVI-D_1 disconnected" in xrandr.

Thanks,
