This is a very strange problem if I understand you correctly. If you login
as root or as a normal user, you can run X fine. But if you login as a
normal user then as root you can no longer start X??? Why would subsequent
logins to your machine (I'm assuming from the console) alter the ability
of your superuser priviliges? I would suggest looking for the s flag in
your XF86 server, but the way you describe your problem makes it seem very
peculiar. Perhaps your /dev/console as weird permissions? You'll have to
be a bit more clear on what exactly you are doing. Are you issuing an su
as a normal user and then it doesn't work? And if you're running xdm,
are you doing the same exact thing, i.e. running root, logging out, then
user then root and it fails? Perhaps you should issue a whoami. As root,
you should be able to run anything as long as the permissions are kosher.
