Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

I'm trying to make my laptop display on a Boxlight projector. I
am also trying to make the laptop display the non-optimum
resolutions the way my other FC2 systems do, namely by
filling the entire physical viewing area rather than a small
central rectangle. I think these two are related.
I used to be able to get my laptop to talk to the Boxlights by
1) connecting up the VGA plug, 2) booting up both devices,
3) pressing Function - F8 simultaneously.
The projected image would flicker and then pop into view.
Using F8 I could toggle between 3 settings: Boxlight on &
laptop off, Boxlight on & laptop on, Boxlight off & laptop on.
Now, since removing RH7.3 and installing FC2 with Xorg,
I can get the laptop to display to Boxlight only during bootup.
When X starts, I get garbled display. I tried to fix this by
switching to the VGA resolution, 800x600, depth = 16 (on
the laptop, I can't change the projector's resolution).
I can edit the xorg.conf file so that it uses these settings by
default, or I can try the command % xrandr -s 3
(where "3" is the index for an 800x600 screen). However,
the laptop shows a tiny rectangular desktop surrounded
by a black boarder and, really, the resolution hasn't changed,
just the number of pixels used.
I have two PC's with FC2 and flatpanel monitors and when I
try the xrandr thing, the display will fill the entire screen.
So what's wrong with the laptop? Also, the laptop is dual-boot
with Windows XP, and the WinXP side can display to the projector
without any problem.
Anyone else solve this problem before?
PS Here are some technical details about the laptop:
Brand: ASL Excalibur
Dual boot Windows XP and Fedora Core 2
Video card: nVidia GeForce 2 Go
Optimum (and recommended) resolution: 1400x1050, depth=24
BIOS set to allow 2 displays
Xorg.conf: (These settings work to give me a 1400x1050 laptop display. But no boxlight)
Identifier "Multihead layout"
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" LeftOf "Screen0"
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
Option "Xinerama" "off"
Option "Clone" "on"
I have a similar problem on a very old laptop with the display being centered in a smaller centered rectangle with console and X... I don't mind the console view but X only disays the problem in slackware after the switch to Xorg from XFree86...(Slackware 7.1 works fine) provided XF86Setup is used to configure X . I don't have a big enough harddrive on the laptop yet to test if this is a difference between Xorg and XFree86 but if you have the time you might want to give it a shot and post back.
