Hi Ben, Thanks very much for the useful feedback! :)
I tried to look into the BIOS, but there seems to be no way I can tell it to initialize both monitors. :( Do you happen to know of a way I could tell it to do so? If that is not possible, what would the next step be to have dual desktop on my system? I tried the proprietary nvidia drivers, but they seemed to be horribly slow in KDE, so I would definitely prefer nouveau instead. If there is any way I can help out implement this feature let me know.
