X windows problems

[Cannon, Andrew]

Hi All,

We are running three Red Hat systems; one RH8 and two RHEL v3 U2 boxes.  All
three have started to exhibit instability with the X Windows system when
logging in on the boxes themselves.  The system basically says that it
"cannot find the font "fixed"".  The X windows server can be restarted (if
you log in remotely) by issuing the command "/sbin/service xfs restart" as
root.  

Strangely, I did this locally as root on the RH8 machine and it logged me in
okay, but when I logged out, X crashed and would then log root in
automatically when I started XFS remotely.  (Have I confused anyone yet?)

Basically, what I am asking is this:

Why would X suddenly start having problems on all three systems when they
are two completely different systems (the RH8 system is a 2GHz P4 Compaq
desktop, and the 2 RHEL systems are 64-bit AMD systems from a UK company
called Evesham).  The kernels are different (RH8 2.4.20-13.8 and RHEL
2.4.21-15.EL) and the version of XFree86 is different (RH8: "Red Hat
release: 4.2.0-72", RHEL: "Red Hat Enterprise Linux 3 Release: 4.3.0-62.EL).

Has anyone else experienced this problem?  If so, how did you fix it?  Is it
possible that we've been hacked?  

Andrew
