So, i tried the Backtrack 2 CD, everything loads up good until i get to write commands.

I first write xconf and then startx, my screen just goes black and i can hear some sound which i assume is "welcome sound". It says that i should try to press ctrl + alt + plus if my screen goes black. I do and still nothing happens, just a black screen.

Could it be because my screen is a widescreen lcd with a somewhat unusual resolution, and how can i fix this?

I'm sorry for my poor english, but hopefully you understand anyway.
