Original ArcadeVGA + Debian Linux

[Dirk the Daring]

I have a stepmania system hooked up to my DDR.. or should I say had...

A couple of days ago, the power supply blew, so I thought this might be the perfect opportunity to switch from Windows XP to Linux for this system.

I hooked up the arcade monitor to the first port, and a standard monitor to the second.

When the system boots, everything is shown on the arcade monitor. About half way through the boot process, everything switches to the standard monitor. Obviously, I want to be displaying on the arcade monitor for the game. Booting with just the arcade monitor connected does not prevent the switch to the standard monitor.

I started playing with xrandr to try to set the display to arcade settings in the hope that the card might smarten up and switch. No go. Here's what I did: (retyped)

$ cvt 640 400 15
Modeline "640x400_15.00" 4.75 640 664 720 800 400 403 409 412 -hsync +vsync
$ xrandr --newmode  "640x400_15.00" 4.75 640 664 720 800 400 403 409 412 -hsync +vsync
$ xrandr --addmode VGA-0 "640x400_15.00"
$ xrandr --output VGA-0 --mode "640x400_15.00"
(This should have changed the graphics mode. There was no change.)
$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
VGA-0 disconnected 640x400+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
    640x400_15.00   14.4*
DVI-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
    1024x768           60.0
    800x600             60.3     56.2
    848x480             60.0
    640x480             59.9
S-video disconnected (normal left inverted right x axis y axis)

Thanks for any help!

I have also tried:
$ xrandr --output VGA-0 --primary

The standard monitor blanks briefly, and when it comes back there is no change.

I have opened this topic in the Linux forum, where it is more appropriate, but I can't figure out how to delete this post.
