I'm running Debian Lenny on a laptop that is always docked, and I have two identical monitors (both HP LP2065) plugged into the dock's VGA and DVI port respectively. The laptop has an Intel "Mobile 4 Series" video chipset.
I have been using this hardware configuration with Ubuntu for years and have always found it to recognize my dual monitor setup out of the box. I am now wishing to run Debian on it but find that the video driver only "sees" one of my monitors. When I run a ddcprobe, I see the following:
vbe: VESA 3.0 detected.

monitorrange: 30-94, 48-85
monitorname: HP LP2065
I am only seeing 1 monitor with this output and figure I should see 2 if my video driver is supporting my dual monitor setup. I get similar results from other programs as well, for example, xrandr only shows me 1 monitor to configure.
I know that my dual monitor setup is possible, but I figure I need to do something to get my driver to see the other monitor and am at a loss how to go about that.
Please help, I need my screen real estate back!
Thanks in advance!
