[Lucid] Exteral monitor never detected on a Dell Studio 15

[Marc Tardif]

Binary package hint: xorg

When connecting an external monitor to a Dell Studio 15 laptop, either when booting or after booting, the external monitor always remains blank. However, when running the Monitors application, the external monitor is detected and it seems like the desktop spans both the laptop and the monitor as observed by moving the mouse to the right of the laptop.

Well, the X side definitely sees your monitor. Looks like it's a BenQ FP91G; good choice! ;-)

Looks like your system is using kernel modesetting. You didn't mention it but I assume this is a regression from Karmic (where we were not using KMS by default?) Probably if you boot with radeon.modeset=0 to switch off KMS it'll behave as it did in Karmic.
I'll go ahead and reforward it to the kernel team.

(Btw, in general now with Kernel mode-setting any bug relating to resolution, output switching, and so on are now kernel bugs.)

Marc,
    I know this is an old bug that seems to have dropped through my net somehow, but do you still have this hardware and if so, is the issue still present?

Thanks!
