At the office, I want to configure my Xubuntu to use both monitors independantly (dual monitor). I have followed a few links but grandr still only sees one monitor.

I tried gksu displayconfig-gtk but it did nothing (nothing shown, nothing displayed, nothing asked, ...)

Does anyone know how to fix this problem ?

Forgot to mention, currently using 2 external LCD monitors.
