Blank screen after existing X windows

[Martin Miedema]

I just installed FreeBSD 6.1 on my Thinkpad T23 (one of my first times 
using FreeBSD) and after wrestling my self through configuring X I'm 
having the following problem:

X starts correctly and opens KDE but when I log it out it just shows a 
blank screen. I can blindly type shutdown -p now or startx (which starts 
X again normally.

The only way for me to shutdown X without facing the blank screen 
appears to be by using CTRL-F1 and pressing CTRL+C

Please let me know if you need any configuration files or logs etc.

Thanks in advance,

Martin Miedema.
