I'm running lenny and I have a 22" CRT @ 1600x1200 as my left screen and

When I boot up both screens come up at 1600x1200 and I have to run the
following command to fix them.
xrandr --output VGA-0 --mode 1600x1200_85 --pos 0x0 --output DVI-0
--mode 1920x1200_60 --pos 1600x0
That is very cool. How did you figure out what to do? I am currently using the
nvidia proprietary drivers
on my system with a 6600GT nvidia dual head dvi video card
1920x1200 on left and 1280x1024 on the right
The thinkwiki
http://www.thinkwiki.org/wiki/Xorg_RandR_1.2
The debian wiki
http://wiki.debian.org/XStrikeForce/HowToRandR12
and the xrandr man page are all useful but I don't know if the
proprietary nvidia drivers support xrandr extensions.
and i have been using the nvidia setup which leaves me with
a total desktop of 3200x1200
where I can't see the bottom of the right screen because it thinks it is 1200 high whereas it is only 1024 so it is off the screen.
That's normal when you're using screens with different vertical
resolutions, (I'm not and yes it's way cool) nowadays it's not a problem
as dialog boxes and windows won't appear in the dead space, I'd set it
up so the screens align along the bottom rather than the top but that's
usually pretty easy.
As far as I can tell the most important bit is the line "Virtual
3520 1200" in the Screen section because the physical desktop size
cannot exceed the virtual one and unless you specify otherwise xorg
makes a guess at start time and often too conservative, with modern xorg
all the Modeline and other timing stuff is usually not needed so a
Monitor section should look like this
Section "Monitor"
Identifier "LCD"
Option "DPMS"
EndSection
With a dual head setup you may have 2 of those sections an L_LCD and an
R_LCD one the first of which would have an additional line like
Option "LeftOf" "R_LCD"
I wonder if the xrandr line can fix it?
would it work with my xorg?
what would i use?
Well it depends what version of xorg you're running with what drivers.
Do some research and update the list to help others in your situation.
Good luck

here is my xorg.conf, I haven't tidied it up, there are a lot of things
commented out from my experimenting and from the evolution of the setup.
