Dual head setup, Fedora 10 KDE, Radeon RV100 QY

lppatmore · 10-10-2009, 12:30 PM

I have two monitors connected to my Radeon RV100 QY card, one to the DVI, the other to the D-SUB VGA. Both resolutions 1024x768. I installed system-config-display, which created an xorg.conf file.

Code:

# Xorg configuration created by system-config-display

Section "ServerLayout"
	Identifier     "single head configuration"
	Screen      0  "Screen0" 0 0
	InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
# keyboard added by rhpxl
	Identifier  "Keyboard0"
	Driver      "kbd"
	Option	    "XkbModel" "pc105+inet"
	Option	    "XkbLayout" "us"
EndSection


Section "Device"
	Identifier  "Videocard0"
	Driver      "radeon"
EndSection




Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Modes    "1024x768" "1024x768" "832x624" "832x624" "800x600" "800x600" "720x400" "720x400" "640x480" "640x480" "640x400" "640x400" "640x350" "640x350"
		
	EndSubSection
EndSection

Attached, you will find a screen shot of the KDE System Settings display dialogue. Notice how the the output of the card is the same to both displays. What should I add to my xorg.conf to enable dual head display, having not had to edit mine before? Any help would be greatly appreciated. Thank you.

What happens if you run 'xrandr --output VGA-0 --mode 1024x768 --output DVI-0 --mode 1024x768 --right-of VGA-0'

Obviously if the monitor on the DVI port is on the left, use --left-of instead of --right-of
