ATI FirePro 2260 Dual monitor problem


Dear All,

I have a new Fedora 14 32-bit installation with a ATI FirePro 2260 Dual-Display professional graphics card (FireMV) that connects through two DisplayPort to DVI-D connectors to two Samsung SyncMaster 2343 monitors.

When I boot the system with both monitors attached only one monitor will be ON but is not the Workspace with the Top&Botton panel so I can't run anything only ctrl+alt+F2,3 etc.. If I swap the cables the results is the same, only one monitor is working and the only thing I can do is to login.

I don't know why but Fedora 14 doesn't have xorg.conf available by default but so I create it running Xorg -configure but any configuration I tried was not successful and sometimes system won't even load any graphics.

Can some one guide me on how to solve this problem ? If I need to manually edit xorg.conf I need assistance as I haven't be able to find any good examples regarding Dual Display.

Bellow my lspci output :

The ATI RV620 chip should be supported by both, the free radeon-driver and the proprietary fglrx-driver. So I would think you have two options to get dual monitor working.
1. Use the free radeon driver and xrandr to set up dual monitors. See
Code:
man xrandr
for details how to set up dual monitors.

2. Use the fglrx-driver and use the Catalyst Control Center for setting up your monitors.
