Xdmx and xrandr problem (3 monitors)

[jaromrax]

Hi,
I have a laptop with intel 945 card. Xinerama doesnot work there (as I finaly googled after many trials),
but xrandr is fine. Thanks to xrandr - I use 2 monitors with one desktop (seamless) like xinerama. A little problem is that intel 945 accelerates only up to 2048x2048, so I use only 2x 1024x768.

So far so good.

Now I want to connect 3rd monitor that is connected to other PC (slave).

I yumed xorg-....-Xdm and I managed to run it (see elswhere) with the other PC (slave .100.10) and I can have a seamless desktop over 2 computers (laptop control and PC slave)

startx `which icewm` -- /usr/bin/Xdmx :2 -display 192.168.100.2:1 -display 192.168.100.10:0 +xinerama -ignorebadfontpaths



BUT

Now the VGA display that is connected to laptop only REPEATS what is on laptops LCD and my xrandr command doesnot work anymore.

RandR extension missing in display 2.0

Help please.
I want to have 3 monitors ( 2 via xrandr on laptop, the 3rd via Xdmx ) with one desktop....

thanks

PS. i tried -xinerama, may be xrandr works only for display :0 ???

Whooow,
I can run xrandr first and Xdmx after.
Then taskbar of icewm dissapears, but it is solvable.
