You'd think this would be easier, but apparently this is a recurring problem and I've already spent 3 hours trying various options in xorg.conf to no avail. I can't really afford to continue experimenting since this is my work PC and I need to get back to development.
Running Ubuntu 8.04. I'm only slightly experienced in Linux, and I'm not sure how much of this info is useful, so I'll just throw it ALL out there.
Hardware:
ATI Raden x1550 (legacy PCI)
Dell 2007WFP (native 1680x1050)
Dell E198WFP (native 1440x900)
Desired setup:
19" on the right, rotation 0
20" on the left, rotation 90 CCW
Using the latest Catalyst drivers, and the checkbox is enabled in the Proprietary Drivers section.
fglrxinfo gives:
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: Radeon X1300 / X1550 Series
OpenGL version string: 2.1.8494 Release
I've also read that pair mode might be the way to go, but "aticonfig --list-pairmode" says:
Error: pair mode is not supported when RandR 1.2 is enabled!
Running "xrandr" gives:

With all this, my right 19" shows up fine, but the left 20" stays black. These monitors are both connected to a KVM (using VGA if that makes a difference), and the dual monitor works as expected on my Windows box. I'm at a loss. Any help is appreciated!
