dual head ATI

March 1, 2006

I have a dual head ATI card:

01:00.1 Display controller: ATI Technologies Inc RV370 [Radeon X300SE]

I want to use the 2 monitors as a big desktop. I won't want 2 duplicate monitors with the same content. Please help me. I searched through many forums but nothing worked for me. not_helping_me I am disappointed that Mandriva did not set up my monitors as I want.

Doesn't look anything wrong with your Xorg. Are you using KDE? You could try adjusting the monitor settings. (Rightclick the desktop, configure desktop, monitor, multiple monitors.)

April 5, 2006

I had the same issue. I was able to 'borrow' an xorg.conf file from another distribution. It utilized merging windows rather than Xinerama. See below:

Hi, if I read your post correctly you are attempting to use 2 monitors as one desktop, not 2 monitors as 2 seperate desktops. This is an option you can have. I use both options at various times, not at the same time though. ;)

If you want the first option then you can use 'twinview' as in the sample xorg.conf below :-

Section "Device"

Identifier "device0"

VendorName "nVidia"

BoardName "NVIDIA GeForce FX (generic)"

Driver "nvidia"

Screen 0

Option "DPMS"

Option "TwinView"

Option "MetaModes" "1024x768,1024x768; 800x600,800x600"

Option "SecondMonitorHorizSync" "24-60"

Option "ConnectedMonitorVertRefresh" "55-75"

EndSection

In this mode you only need the one "Device" section but still describe 2 "screen" sections and use the same device for both screens. Although my card is NVidia I believe it is the same for ATI just a different driver.

The option I use most is 2 monitors as 2 seperate displays which is what you are describing in part of your xorg.conf.

Mine is :-

Section "Device"

Identifier "device1"

VendorName "nVidia"

BoardName "NVIDIA GeForce FX (generic)"

Driver "nvidia"

Screen 0

BusID "PCI:1:0:0"

Option "DPMS"

EndSection

Section "Device"

Identifier "device2"

VendorName "nVidia"

BoardName "NVIDIA GeForce FX (generic)"

Driver "nvidia"

Screen 0

BusID "PCI:1:0:1"

Option "DPMS"

EndSection

When using this type of display you don't need to use 'twinview' or 'xinerama'.

As far as I can see there is no problem with the rest of your xorg.conf

I hope all the above makes sense to you. It looks complicated but you seem to have a grasp of the general idea, it's just maybe you didn't realise there were two different ways of displayng the desktop(s).
