I need some help with LXDE

I have been unable to get LXDE working since I got my 'new' computer and installed Slackware 15. After several attempts to get it working using sbopkg. today I installed all the files for LXDE from Ponce's web site but am unable to get it to run as user. It seems to work fine if I log in as root however. Any help/ideas would be greatly appreciated.

Thanks
Dan

P.S. As user all I get is a black screen
