Getting my projector to work...

Hi all,

I currently have a Mandrake 10.1 box which I'm hooking up to my projector via an nvidia fx5200 board. I want it to display 1280x720@60. So, I first get the modeline like this:

/usr/X11R6/bin/gtf 1280 720 60 -x

which gives me

# 1280x720 @ 60.00 Hz (GTF) hsync: 44.76 kHz; pclk: 74.48 MHz
Modeline "1280x720_60.00" 74.48 1280 1336 1472 1664 720 721 724 746 -HSync +Vsync

When I restart my box, the Xorg.0.log file says:

(II) NVIDIA(0): Not using mode "1280x720" (no mode of this name)

It the goes on to state that:

(II) NVIDIA(0): Not using mode "1280x720_60.00" (width too large for virtual size)

1) What does it mean when it says there is no mode by that name?

2) Why is this width too large? Surely the 5200 can display this?

Hope somebody can shed some light on this.



Here's my xorg.conf:
