Dual head help needed

estrabd

estrabd

First, let me profusely appologize for it coming to this. I have tried in vain to compose an xorg.conf that provides me with the dual monitor experience, which I seek. At this point, I am just trying permutations of things, and it's getting frustrating.

I get a fine image, but it's the same on both monitors. I'd like one to extend the other.

Info:
  • xorg-7.4_2
  • driver: xf86-video-radeonhd-1.2.5_2 X.Org
  • card specs:
    • "ATI Technologies Inc"
    • "RV530 [Radeon X1600]"
    • "PCI:1:0:0", "PCI:1:0:1" (SVGA, DVI, respectively)

Any help or pointers would be greatly appreciated, including a kindly "your card can't do this" nudge;

TIA,
Brett :stud

First, I recommend 'radeon' over 'radeonhd'. Second, remove the second Monitor, Device, and Screen sections, and the entry for that screen section in the ServerLayout section. Then restart X, bring up a console and run 'xrandr'. You should see two output devices, probably DVI-0 and VGA-0. Then try to place one of them to the right of the other with 'xrandr --output VGA-0 --right-of DVI-0' (assuming, of course, that VGA-0 is on the right). Let us know how you make out.

Thanks!

I had to play around with the xrandr parameters, but I matched it up with the resolution in xorg.conf; I also added the line to my ~/.xinitrc, and it works like a charm.

Here's the new xorg.conf;
