[newbie] blank screen on X

[Joe]

hi guys, I cant get my X running after I installed linux. I run Xconfigurator, and when it came to the part of testing of the conguration all I get is a blank (black) screen with the mouse pointer. I can move it around though, then a message popped out saying that there was something wrong with my configuration. I tried many combination including the resolution given by the probing, but what I get was still the blank black screen. Can somebody help me ? thx ... btw, I installed Mandrake 6.0   regards,   Joe
