Bug Description
Binary package hint: xserver-
I'm using Ubuntu 8.10. I have a new Dell Optiplex 960 - this machine has a built in Intel graphics controller with a Dell displayport digital output, in addition to a normal VGA output. If I connect the PC to my Dell 2408WFP monitor via the displayport, everything proceeds fine up to the point where X tries to start, at this point the Intel video driver fails to detect any connected monitors and bombs out. Ubuntu responds by re-starting X with the VESA driver, which works (although slowly and with resolution below that which I want to use). If I connect the monitor via the VGA port, everything works fine - X boots successfully using the Intel driver (although I would obviously prefer to use the displayport connection for quality reasons). The PC/Monitor combination works fine using displayport if i boot in Windows.
I tried compiling the latest version of xf86-video-intel from source (V 2.6.99.1) - the problem does exist in this latest version of the driver too.
xorg.conf is not changed from the standard Ubuntu

Hi junkmail-invades,
Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.
