Dual Monitor Setup

[GodofPain]

I have the PCI ATI Radeon 7000 64MB DDR Video Card w/Dual VGA Head & Tv Out and had a hard time making both displays work not as clone.

This is my xorg.conf that works on my system.

Hey, I have a ATI RAdeon 9800XT AGP8x, and am also trying to get dual displays working... i have 2 17" CRT monitors(one is a Viewsonic A71F+, the other is a Philips 107S)...

here's my original xorg.conf...

thanks in adv.

[antidrugue]

No, I don't believe it will work like that, you are using the generic "VESA" driver for your ATI 9800XT, that is a big waste, as it won't give you much performance or functionnalities.

First install the ATI proprietary drivers, then you can think about a dual-monitor setup.


Recent ATI drivers comes with an utility to automaticcaly configure dual-monitor setup. Just backup your existing /etc/X11/xorg.conf and then (given you have properly installed ATI proprietary drivers) run something like that :

aticonfig --initial=dual-head --dtop=horizontal --screen-layout=right --iagp=off -v

More info here :
http://gentoo-wiki.com/HOWTO_Dual_Mo..._binary_driver

If you want more help, please tell us the distro you are using, as well as your exact 2 monitors model.
