I’ve just bought ViewSonic VA2226w from Lowyat, and has been able to use it in dual monitor mode with my XPS M1330 (nvidia based) and Kubuntu. The ViewSonic that I bought is a 22" LCD monitor with resolutions up to 1680×1050 (only just as high as my 15.2" Inspiron 6000′s screen)..
I was using nvidia-config to configure the dual display, and after some trial and error, I come out with this /etc/X11/xorg.conf file:

@Bonar: I’ve tried it on compiz before, and I can say that it works fine, but only if xinerama is not enabled.

I have the same viewsonic va226w monitor. I got the resolution set the right way. the color profile isn’t right though. the colors are all washed out and messed up. I have messed with the rgb, contrast, and brightness settings. it must be something else. here is the part of the xorg.conf file that I would like to see from a working setup.
Section “Monitor”
Identifier “Generic Monitor”
Vendorname “ViewSonic”
Modelname “ViewSonic VA2226w”
Horizsync 30-82
Vertrefresh 50-75
modeline “1680×1050″ 146.25 1680 1768 1944 2240 1050 1053 1059 1089 +hsync -vsync
Gamma 1.0
EndSection
any other ideas.

Very helpful! I now have a ViewSonic VA2226w setup with a Philips CRT 107T 17 inch monitor connected to a GeForce 7300 GT video card, but both display exactly the same content (just duplicates). I want to extend from one monitor to the other – any suggestions? Is the “Twinview” option something to do with it?
