Hello. I am having a problem configuring a dual monitor setup on my Kubuntu Feisty dist.

I want to have a dual monitor setup that extends horizontally the desktop across two monitors. I can achieve this, but the problem is that i cannot enable maximizing the windows across both monitors with 3D acceleration.

I need to use the fglrx driver (ATI), so using Xinerama is out of the question because i lose the 3D acceleration

The alternative is to use BigDesktop (the TwinView correspondent for ATI), and with this i can achieve the desktop to be horizontally across both monitors, but i need the windows to be maximized too along both screens, and what i get with BigDesktop is when I maximize a window it only occupies one screen, leaving the other empty. With Xinerama i can get this done, but it does not support 3D acceleration.

maybe there is a way to configure this in kde? (i cannot fin though...)
or some other option in xorg.conf, but i've been reading the man pages of fglrx and i tried pretty much everything that seemed logical...

my xorg.conf:

Section "Device"
Identifier "aticonfig-Device[0]"
Driver "fglrx"
Option "no_accel" "no"
Option "no_dri" "no"
Option "VideoOverlay" "on"
Option "OpenGLOverlay" "off"
Option "DesktopSetup" "horizontal"
Option "OverlayOnCRTC2" "1"
BusID "PCI:64:0:0"
EndSection


thank you for your attention

Option "TwinViewOrientation" "Clone"
or to extend it the you'll have to
Option "TwinViewOrientation" "RightOf"

1st add an other display device
then Add another Monitor

then Add another Screen

then the ServerLayout block

that should do the trick

thank you for your answer.


Actually Xinerama works great, but i can't use it since it does not support 3D acceleration.

Twinview i can't use also because it is only for nvidea cards and i have an ATI
