Forcing VGA video on for nVidia nv50 (Lenovo T61p)

[BRM]

I have a Lenovo T61p system that I have been running with Linux for several years now. It generally works great, and the latest KDE releases make things really slick, with one exception...

I use it in dual monitor mode regularly with the LCD screen and a DVI screen; but I need to use the VGA port for some presentations now, but...

If I plug a monitor into the VGA port, it announces itself via EDID, is picked up, and KDE's Quick Display manager finds it and works. However, I have a projector that doesn't seem announce itself via EDID on its VGA (it's old - Mitsubishi XL1U); so KDE Quick Display manager won't add the VGA-1 as an option to enable. Xorg doesn't see it, so no surprise KDE doesn't either.

I'm using the nouveau driver as Kubuntu uses it out of the box, which uses KMS as far as I can tell. Is there any way to force the driver to enable the VGA so I can use the projector with this laptop?


DDCcontrol seems to be out of date, no longer supported, and doesn't list 'nouveau' driver at all. And the nv50 (according to get-edid) doesn't support DDC1 or DDC2.

Still, there ought to be a way to force the output on, no?

TIA,

Ben
