KDE 4 Black Screen on Load

[z662]

I recently formatted my machine (refer this thread http://forums.freebsd.org/showthread.php?p=134374&posted=1#post134374) and now am having issues loading KDE4 up. After running startx the KDE login appears to be working properly, and shows the loading of the 5 icons, however once it loads the 4th icon, it immediately goes to a black screen but the cursor still appears. It seems to me like the desktop doesn't finish initializing and fails to load anything. I can post any relevant files needed. Not sure what to do at this point.

Was able to fix it, although not sure why my solution worked... I ran the configure script for X to get a bare configuration of KDE running (no dual monitors, hardware acceleration etc.) Then I went into System Settings and turned off "Desktop Effects". Then reverted to my real xorg.conf and was able to get it working as desired. In case someone has similar issue below is my xorg.conf file after I turned off "Desktop Effects"
