Hey folks,

at my workstation I'm using 2 NVidia Quadros and 4 TFTs.
I already got the dual/quad view working by configuring the xorg.conf file.

But I've got a small problem in expanding the desktop over all the four displays.
The taskbar (panel) is just on the first two monitors. The other two screens work well, I can move a window on them, but when I maximize a window, it either fills the first two displays or the other two.

Here's my ServerLayout Section:
Code:
Section "ServerLayout"
	Identifier     	"Default Layout"
	Screen 		"Screen0"
	Screen 		"Screen1" RightOf "Screen0"
	Option		"Clone" "off"
	Option		"Xinerama" "on"
	InputDevice    	"Mouse0" "CorePointer"
	InputDevice    	"Keyboard0" "CoreKeyboard"
EndSection
I think the problem is in the ServerLayout there are two Screens declared. If there was only one screen, the taskbar would fill the complete width of all 4 displays and windows would maximize over all the displays.

Now my question: How can I solve this problem? Maybe it's possible to combine the two screens to one so the x server has only one screen as desktop?

Thank you very much
