Hi Folks,

System: Fedora release 16 (Verne)
KDE: 4.8.4 (4.8.4)

I'm new to Fedora and KDE so please excuse me if I am posting in the wrong place.

I am attempting to set up two monitors and am having trouble getting Fedora to recognise the second monitor - at present, all the second monitor displays is a mirror of the first.

Here's what I've been able to gather:

1) The Display Info in the Sysinfo screen is blank
2) The Display and Monitor Window in System Settings only shows one monitor (default) - Clicking on "Identify Monitor" shows "default" on both screens
3) lspci -vv shows:
03:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3470 (prog-if 00 [VGA controller])
Subsystem: Dell Device 3243

Region 4: I/O ports at 2000 [size=256]
Expansion ROM at e1400000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel modules: radeon
4) xorg.conf has:
Section "Device"
Identifier "Videocard0"
Driver "vesa"
EndSection
5) xrandr gives:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1440 x 900, maximum 1440 x 900
default connected 1440x900+0+0 0mm x 0mm
1440x900 0.0*
640x480 0.0

Any help would be very gratefully received.

Kind Regards,

Luke

Driver "vesa"

Check /var/log/Xorg.0.log - if really in use, i doubt the vesa driver can do multiscreen.
Notice that there's a difference between the radeon kernel module and the Xorg driver. You want to install xf86-video-ati
