hi everybody!

i just have a little problem.
im running backtrack 4 pre-final perfectly on my notebook, i installed it form the live cd, and everything works fine!

after that i tried to install it on my desktop-pc, i put in the live cd, and after the "startx" my monitor gets black and it written "out of range" on it!
i can only boot the livecd in "secure graphic mode", but after the install and "startx" i get a black screen again.
i think its something about the resolution, im using a 22" monitor from asus (1680x1050)

can i boot backtrack in a smaller resolution before "startx"?

i hope anybody is able to help me!
