try this:

go to /etc/X11 directory and type this:

Xorg -configure

a new file will be generated as

backup and rename the old xorg.conf

mv xorg.conf xorgbackup.conf

rename the generated file as xorg.conf:

mv xorg.conf
restart and check if you will have the GUI

Good luck!!!

Why would you log into X as root ?

Please try : # su - <user-name>
I.e. "su <space> <hyphen> <space> <name-of-unprivileged-user>

Then you should be able to do $ startx
( When you have a usable xorg.conf ).

** Not sure if you can log into X as root, unless you edit the OS.
Anyway it is dangerous to run a Desktop as root. Very unsafe.
And : Not at all required.
