Xubuntu Synergy + Dualhead on Latitude D600 for triple head display

Well after 3 days and many hours scouring xorg.conf and synergy.conf files I have a working triple head display that utilizes the computing power of two PC's.

Okay first the setup.

I have a Dell latitude D600 laptop, this shares the wireless via tinyproxy to desktop over 10base network this machine is known as hiddenslap
The graphics card in hiddenslap is from lspci:-

01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 02)

If you have a different card then this one YMMV goodluck and have the moutain dew handy.

The other machine is an Intel based Desktop, nothing fancy anything running X should work.

Okay first you need to install synergy on both machines

a quick sudo apt-get install syngery will achive this

then install xrandr on the laptop by typing in sudo apt-get install xrandr

I found a great shell script that automates the switching of diffrent layouts ie. Mirror, "Big Desktop", Dual Head, CRT only and LCD only. You can find it here output-switcher. I added it as a launcher on xfce panel and can now quickly switch layouts :) cool

I used the documentation over at HowToRandR12 as well as many, way to many other forums and howtos to mention before I got this to work. The above tutorial was the best one.

You have to run synergys --config /etc/synergy.conf on the laptop it is the server, if you use the dektop as the synergy server you cant get across to the second screen (if anyone knows a fix to this please leave a comment)

Run synergyc on the dekstop

there it should be working, run sh /output.sh on the laptop to switch from mirrored to extended etc or add it as a launcher to the panel.

and the most important thing here are my xorg.conf and synergy.conf files that give me a virtual triple head display with my laptop LCD in the middle the CRT running as a secondary to the laptop is on the right and the seconf mac

/etc/X11/xorg.conf
