Cannot start X session as any new user

[Fibonacci]

Hello,

I have recently discovered that I can't start an X session as any user other than myself or root. After creating a new user account for the umpteenth time, and trying to login, be it using gnome or KDE, I only get this error message:

Your session only lasted less than 10 seconds. If you have not logged out yourself, this could mean that there is some installation problem or that you may be out of disk space. Try logging in with one of the failsafe sessions to see if you can fix the problem.

View details (~/.xsession-errors file):

/etc/gdm/PreSession/Default: Registering your session with wtmp and utmp
/etc/gdm/PreSession/Default: running: /usr/bin/sessreg -a -w /var/log/wtmp -u /var/run/utmp -x /var/gdm/:20.Xservers" -h "" -l "20" "invitado"
PRNG is not seeded

Strange thing is, there is no .xsession-errors file in the home directory of the new user. Or in any home dir, for that matter.

What am I doing wrong?

Thanks in advance,

-Fibo

Is there anything in these log files ?:
/var/log/Xorg.0.log
/var/log/messages
/var/log/secure

Sould like a file permissions setting somewhere...the new user is not allowed to start
something needed by X.

What does Xorg look like ?

ls -la /usr/bin/Xorg

/var/log/Xorg.0.log

Too long, see attached file.

Any new user?
