Hello
I am trying to set up and dual monitor setup here, with a monitor and a tv, the monitors resolution is 1680x1050, the tv's resolution is 1360x720, which results in that the desktop will have an resolution on 3040x1050.
When I try to do this with GNOME's xrandr gui, I get this:
required virtual size does not fit available size: requested=(3040, 1050), minimum=(320, 200), maximum=(1920, 1920)
When looking in the motherboards manual, it states that each out of my graphics card can do a resolution of 1980x1080. Is the intel driver missunderstanding something? Since both the dvi and hdmi output only delivers 1360x720 and 1680x1050, 3040x1050 is only an virtual resolution.
Any suggestions?
Use the Source, Luke!

... 3040x1050 is only an virtual resolution.
Any suggestions?
Yes, you need to set that virtual size in your xorg.conf, Section Screen - Subsection Display: Virtual 3040 1050
You need to install an RTFM interface.

Uhm do I only need one Screen section?

Yes, with XRandR you don't need two, everything can be done dynamically so you don't need to do a setup like with Xinerama. You still could do a static setup if you want (and it's done a little differently then you did). Check my xorg.conf for both situations.

Notice that on intel cards you won't be able to get DRI once you go over 2048x2048 on resolution.

Only on cards prior to X3100.

I knew I would benefit of buying the latest intel card:D
You xorg config is quite huge, it only confuses me, can someone explain more simpler to me how do this is working, how do I create a dual monitor setup that is static?

A little offtopic, how is the radeon driver working on r700 hardware?

Okay I think I got it right now, but I only get a black screen when I start the xserver.

And when I comment out the virtual resolution line, it starts, what am I doing wrong?
EDIT: appearantly I can't either stop the xserver when it turns black, maybe it locks up while starting it?
