Dual Monitors in Openbox.

[Maccabee]

The title pretty much says it all. I have tried a lot of stuff, and none of it worked. Can anyone just guide me through it?

If I can't get this to work, I'm moving back to windows, which will be pretty sad. Right now, both monitors are just mirroring eachother. Also, I can't get my video card drivers installed! but thats another thread. I think.

Ok, here's some more info. I tried using this, xorg.conf file:

But then when I reboot, and enter startx I get an error saying there are no monitors. So I edit the xorg.conf file in nano, and just delete everything then enter startx, and it boots like normal.

Also, my video card is a ATI Radeon 9500.

Try the xrandr style xorg.conf.

In a few minutes I'll post my xorg.conf, I need to fire up Linux.

This is set up for 1680x1050 and 1280x1024, so change that to fit your needs.

The key is the line Virtual 2960 1050.
You'll need to change that to your resolution though. It's monitor1's x res + monitor2's x res, and the y is just whatever is your tallest monitor.

1680+1280 = 2960 = x
1050 = y

1680+1280 = 2960 = x
1050 = y[/QUOTE]

Ok, I'll try your xorg.cong.

so the virtual will be 2048 1024
And one monitor is vga, the other is dvi, so should I change that? And of course, my monitors arent acer and dell. Should I just swap anywhere I see acer wit microtek and dell with mag?

[editline]09:58PM[/editline]

I just copy and pasted that into /etc/X11/xorg.conf, with the virtual line, edited for my needs, and saved, and rebooted, and I got an error saying:

Fatal server error:
no screens found

What what?

[editline]10:41PM[/editline]

Yaaayyyy! I edited, the xorg.conf file, and then used arandr, set it how I wanted and clicked apply! It totally works!

This can be locked or whatever.

It's good you found a solution already, but I think that error means you needed to add the Screen identifier to the ServerLayout section.

I had a line for that in my xorg.conf, but it was commented out for some reason, so I snipped it from what I posted.
