So while searching the TC extensions repository for some mouse configuration tools, I spotted an app called synergy. Intrigued by the name, I decided to check it out.
It's amazing. Getting it running on two TC machines is easy. First step is to install the tcz for synergy. Then create a config file (/home/tc/.synergy.conf) as below on one laptop.
section: screens
boxd:
boxc:
end
section: links
box:
right = boxc
boxc:
left = box
end
Then run:
synergys --name boxd
On the second machine, run(replacing with the IP address of the first machine):
synergyc --name boxc 192.168.2.100
Voila. Simple as that, the one keyboard and mouse now controls both screens. It's not quite the same as two monitors on the one laptop, but it's just as good! Even the clipboard gets synchronised.
