configuring 2 graphics cards
Hi,
I'm using Ubuntu 9.04 with 2 graphics cards (ATI X1300 both).
After installation 1 monitor on one card worked fine.
I also managed to start Ubuntu with dual monitor support (on one graphics card).
Now I want to activate my 2nd graphics card in order to use my 3rd monitor too. After searching on the web my xorg.conf is as follows:
Code:
Section "Device"
Identifier "Dev1"
BusID "PCI:1:0:0"
Option "DVI-0" "Monitor0"
Option "VGA-0" "Monitor1"
EndSection
Section "Device"
Identifier "Dev2"
BusID "PCI:4:0:0"
Option "DVI-0" "Monitor2"
EndSection
Section "Monitor"
Identifier "Monitor0"
EndSection
Section "Monitor"
Identifier "Monitor1"
Option "RightOf" "Monitor0"
EndSection
Section "Monitor"
Identifier "Monitor2"
EndSection
Section "Screen"
Identifier "Screen0"
Monitor "Monitor0"
Monitor "Monitor1"
Device "Dev1"
SubSection "Display"
Virtual 2800 1050
EndSubSection
EndSection
Section "Screen"
Identifier "Screen1"
Monitor "Monitor2"
Device "Dev2"
EndSection
lspci shows:
Code:
01:00.0 VGA compatible controller: ATI Technologies Inc RV515 [Radeon X1300]
01:00.1 Display controller: ATI Technologies Inc RV515 [Radeon X1300] (Secondary)
04:00.0 VGA compatible controller: ATI Technologies Inc RV515 [Radeon X1300]
04:00.1 Display controller: ATI Technologies Inc RV515 [Radeon X1300] (Secondary)
Unfortunately the 3nd monitor is still black.
What else can I do ???
Thanks.
