The BigLig Thinks

Can't think why this isn't do-able with a tool instead of having to hack xorg.conf... Anyhow, following the guide here I eventually got to these lines in the Device section. (Make sure you have the nvidia driver, not the nv one):
Option "TwinView" "True"
Option "UseEdidFreqs" "True"
Option "MetaModes" "1680x1050,1680x1050"
Option "UseDisplayDevice" "DFP,DFP"
Option "ConnectedMonitor" "DFP,DFP"
Option "TwinViewOrientation" "RightOf"
Option "SecondMonitorHorizSync" "65"
Option "SecondMonitorVertRefresh" "60"

Lovely. Next up is getting WINE to run netsupport, my remote control application, and finding some sort of decent mail application - I don't really like Evolution.

(OK, OK, next is starting Beryl and seeing if my new xorg.conf makes any difference!)
