unable to open display

[ole123]

i am running Fedora 5 with twm (simple windows manager)

i log in as a root

i am able to start X but when i try to run some graphical programs (say, myprog) i get:
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

myprog: unable to open display ":0.0"

when i run xhost +localhost
i get the same error message

when i run:
xauth -f /root/.Xauthority extract -$DISPLAY | xauth merge -

i get
xauth: error in locking authority file /root/.Xauthority
xauth (argv):1: unable to read any entries from file

where do i go from here?
thnx

seeing as the repos and yum do not work on fedora 5 any more .
Have you built and installed any new programs
--
also WHY are you booting into text only
and starting x by hand ( or it this new because x wont start
you can try renaming xorg.conf to xorg.conf.backup
also try renaming /home/( user name)/.gnome to .gnome.old
I don't think that old and unsupported version of fedora has .gnome2 but if it is there rename it to to .gnome2.old
then restart

i switching into booting mode 3 when the system crashes in X mode. it is easier to debug this way...

i hit post to soon there is an edit i added

.gnome is not in the system..
why you mentioned xorg.conf? is there a section that is responsible for security?
