Hi all--
I rebooted my machine the other day, and now gdm returns error messages
and won't start.
Here's what I've tracked down so far.
-The X server starts
-I get error messages <follows> stating that the client is not authorized
to connect to the Xserver
<snip>
AUDIT: Mon Apr 2 01:08:55 2001: 4531 X: client 1 rejected from local host
Xlib: connection to ":0.0" refused by server^M
Xlib: Client is not authorized to connect to Server^M
</snip>
-The problem seems to be within xauth; when I run 'xauth generate :0' I
get similar error messages.
Xlib: connection to ":0.0" refused by server
Xlib: Client is not authorized to connect to Server
xauth: (argv):1: unable to open display ":0".
-Strace from 'xauth generate :0' gives me the following. I have only
included what I feel is the pertinent section....

unlink("/root/.Xauthority-l") = 0
umask(022) = 077
_exit(1) = ?
</snip>
-I reinstalled gdm to make sure that one of those package files didn't get
corrupted, and also did a verify check on the package <before and after>.
I am at a bit of a loss making sure that I understand everything in the
strace output. There were no -1 values returned, and preliminary digging
as to where to start hasn't really given me any good leads.
One thing that I am curious about is my :0.log output that states unable
to connect to "local host"...wondering if it should be "localhost" and
there is a problem with that?
I am not positive, but I think that the only packages that I have
installed since the last reboot were glibc 2.1.3 and java 1.3. My
searching on the web led to a lot of references to regernate the xauth
file, and checking the gdm.conf...at that point, I'd already tried the
xauth route, and I haven't touched the gdm.conf file..but checked it
anyway, and everything seems to look OK.
One of the references I found on the web was a question as to a problem
with glibc 2.1.3 and gdm? <this is partly why I reinstalled gdm> Has
anyone else run across this? I haven't played with file permissions at
all, but I am wondering if this might be a problem as well....I have
deleted my previous magic cookie files and the xauth:0 file </var/gdm> to
make sure that they were regenerated, and that didn't fix the issue
either.
oh, before i forget... I'm running redhat 6.0 ..
i can't think of any other facts to include..if i've missed something,
please let me know....
