I have a problem with gconf/gdm/Xorg, which I _think_ is PAM-related.
Briefly,
to cure some other problems, I re-installed the X system, which cured
the other
problems but left me with a problem on the system console. That is,
the console
does not start into the default window, but simply sits there with a
spinning wheel.
I can escape into a text window, and then run startx, which brings up
a (mildly
broken) window configuration. On the other hand, if I start up
vncserver and log
in remotely, I get a normal windowing session.
What I'm seeing in the logs is:
in /var/log/audit/audit.log
type=USER_LOGIN msg=audit(1178003546.576:11335): user pid=3569 uid=0
auid=4294967295 subj=system_u:system_r:xdm_t:s0-s0:c0.c255
msg='acct=unknown: exe="/usr/sbin/gdm-
binary" (hostname=sc1.snu.ac.kr, addr=127.0.0.1, terminal=:0
res=failed)'
type=USER_AUTH msg=audit(1178003546.629:11336): user pid=3569 uid=0
auid=4294967295 subj=system_u:system_r:xdm_t:s0-s0:c0.c255 msg='PAM:
authentication acct=? :exe="/usr/sbin/gdm-binary" (hostname=?,
addr=?, terminal=:0 res=failed)'
in /var/log/secure
May 1 17:21:30 sc1 gdm[3569]: pam_succeed_if(gdm:auth): error
retrieving user name: Conversation error
repeated ~1000 times per minute
As best I can figure from the PAM audit messages, this appears to be
a problem with process 3569 attempting to do something with an
unknown 'account', which I assume is one of its 'user' properties?
When I check the process, I get:
ps -o egroup,ruser,suser,fuser,f,comm,label 3569
EGROUP RUSER SUSER FUSER F COMMAND LABEL
root root root root 5 gdm-binary
system_u:system_r:xdm_t:SystemLow-SystemHigh
ps -o egroup,rgroup,sgroup,fgroup,f,comm,label 3569
EGROUP RGROUP SGROUP FGROUP F COMMAND LABEL
root root root root 5 gdm-binary
system_u:system_r:xdm_t:SystemLow-SystemHigh
which looks OK to my limited understanding. I've tried re-installing
PAM (and just about everything else I could think of), to no avail.
Does anyone have any suggestions? Anywhere else I should look for
useful diagnostics? This has left me without a system console for six
months or so, so any help would be appreciated.
(maybe) relevant system info:
Fairly stock FC5 installation on an ASUS (intel) motherboard; I
haven't deliberately done anything to change the X, gdm, gconf setup
(other than to re-install it).
Thanks and Best Wishes
