hi all,
ive been trying to get two monitors working as of late but the only thing i can do is get it to work with Xinerama. i have a nvidia card so i tried twinview but it didnt work. however i came accross the $KDE_MULTIHEAD environment variables for kde. my question is how can i get dual heads to work(spaning a screen accross two monitors), and can kde do this by its self?, what is that config option in kcontrol - Peripherals, Display, multiple monitors tab. and how do i set environment variables for kde.

Thanks mute

ps. if anyone has a spaned desktop can u post ur xfree86 (xorg,etc) file please.
i am running kde 3.2 mandrake 10.1 community and have geforce 5200fx

I thought that works only alone with the XFree? Isnt xinerama exact what you search for?

Section "ServerLayout"
Identifier "Default Layout"

# Now enable dual head mode:
Screen "Screen1"
Screen "Screen2" RightOf "Screen1"

# This enables Xinerama. If you don't set this to "on", startx will spawn
# two indepentent X sessions. In Xinerama mode, both screens are virtually
# one screen and only one X session is started.
Option "Xinerama" "on"

That should be in your XFree file. No clue how to do it with kde.

hope that works

Hope this helps you. The mouse is vanilla serial 2 button + wheel type. Monitors are twin CRT - main on left, secondary on right.

Hey Thanks alot perryub. Its always the simple things, i didnt have twinview "true" under server layout only under device. It works great!!

ps. under kde if u want to use config your desktop utility you need to have Xinerama running. i got it to work but Xinerama does not have hardware accel so my advise is to buy a nvidia card.
