from command line, cut down your large log files by locating them...

# find /var/log -type f -size +2000k -exec ls -lh {} \; | awk '{ print
$8 ": " $5 }'

and any file that is really large (i.e. /var/log/Xorg.0.log)

command line empty it...
# > /var/log/Xorg.0.log

if startx only works as root, it sounds as if some permission isn't
correct (possibly /etc/X11/xorg.conf is not 644, readable by all users).
Of course if that were the issue, /var/log/Xorg.0.log would tell you
that or if it were some other permissions issue, the problem would
probably be listed in /var/log/messages

On Fedora 9, it often is enough to just do something like 
# mv /etc/X11/xorg.conf /etc/X11/xorg.conf-bak
# shutdown now -r

and it is automatically rebuilt upon reboot
