I was hoping to set up two monitors, 1600x1200 each -> 3200x1200 virtual. When I attempt to do so, I get the message (paraphrased since I cannot copy it) “required virtual size does not fit available size: requested (3200, 1200), minimum (320, 200), maximum (1600, 1600)”.
1600x1600? That’s an odd limit.
There seems to be more than enough RAM to accommodate the requested size.
What is the limiting factor? Can it be bypassed?
Try adding
Virtual 3200 1200
to /etc/X11/xorg.conf.d/50-screen.conf. (It used to be added to the screen section of /etc11/X11/xorg.conf when required).

Tried that. Made no difference.
I’m tired. Maybe an idea will pop up tomorrow…
Are you using the radeon or proprietary fglrx driver? How are you trying to set up the two monitors (eg xrandr, xorg.conf config)?

The custom fglrx driver. Initially I was using the “Configure Display Settings” icon on the window panel. It left a bit to be desired.
Thank you for the references. They jogged my brain in the right direction.
I got it to work. I went into the “ATI Catalyst Control Center” and, after 4 tries using different combinations of placement and options, got mostly what I wanted. The “mostly” bit is that the Gnome window panel is on the right side monitor rather than the left, and windows always open on the right; I can easily live with that.

Yes, if using the fglrx driver, the ATI CCC is the way to go. Good work.
