cannot log in via display manager (XDM/KDM)

I have been having problems logging in using kdm (kdemod) for some weeks now. I haven't been able to resolve this, but here's some info I'm hoping might be relevant to solve it.

KDM loads nicely. It's only when I try to start a session, it continually dumps me back into kdm (even console login from kdm doesn't work). I can still start kde (or any environment) with startx. However, if I use startkde or fluxbox, it won't start and asks if I have set my display variable.

Here's my .xsession-errors file:

$ cat .xsession-errors
You are now in Atlanta, Georgia.  Please set your clocks back 200 years.
No protocol specified
$DISPLAY is not set or cannot connect to the X server.

(the atlanta comment I guess comes from my fortunemod set in bash. don't know why it gets dumped in there as well, but I can't log in with my guest account in kdm either, and there's no fortunemod set in bash for that user).

edit: I tested this with XDM and had the same problem there, so it's not kdm specific.

Re: cannot log in via display manager (XDM/KDM)

I have the same problem, just started last night.  I can log into a console, but not a display manager (I've tried all of them).  sill looking for the answer.

Re: cannot log in via display manager (XDM/KDM)

I don't think this will help, but out of sheer curiosity..

do:

export DISPLAY=:0.0

Perhaps under your account first then root account if no dice, via another virtual terminal. Then try logging in. o.O

Re: cannot log in via display manager (XDM/KDM)

I guess you must have already tried it, just to be sure, you tried deleting .kde4 and try logging in? Also with connect() failing, X seems to resolve your hostname and connect via tcp/ip? Can you try setting up X without tcp/ip connection? my 2 cents

Re: cannot log in via display manager (XDM/KDM)

I did try deleting .kde4.  The weird thing is that at one point this was fixed, I deleted a bunch of . files from mu user folder and everything started working again.   When the problem came back, removing these files did nothing (I went as far as moving my entire home folder).

As far as the the tcp/ip stuffs......I have no idea

Re: cannot log in via display manager (XDM/KDM)

I had exactly the same problem.

I changed the following two lines in /etc/security/pam_env.conf:

REMOTEHOST DEFAULT=localhost OVERRIDE=@{PAM_RHOST}
DISPLAY DEFAULT=${REMOTEHOST}:0.0 OVERRIDE=${DISPLAY}

to:

#REMOTEHOST DEFAULT=localhost OVERRIDE=@{PAM_RHOST}
#DISPLAY DEFAULT=${REMOTEHOST}:0.0 OVERRIDE=${DISPLAY}

In other words, I commented out these lines.
After I did this, I could login using KDM!

Perhaps this helps.
