xdm trouble - xorg-xdm 1.0.1-1

Good morning

I've got a strange problem with xdm here. I am using testing, so I was using the xdm from the old xorg-clients package, which worked great. Yesterday I updated and I now have xorg-xdm 1.0.1-1.

xdm starts fine (from inittab with /usr/bin/xdm -nodaemon), then I log in, and after successful login, X exits and I am back at the xdm login prompt. I can't find any error messages whatsoever. My $HOME/.xsession file is the default from /etc/skel (which creates a login shell and executes .xinitrc) and startx still works great.

My logs don't give me much information:

Feb 21 01:03:05 gollum xdm(pam_unix)[1889]: session opened for user thomas by (uid=0)
Feb 21 01:03:05 gollum xdm(pam_unix)[1889]: session closed for user thomas

I tried xdm -nodaemon -debug 100 from the commandline, but the output isn't that promising:

I also noticed that the login attempt leaves the three files $HOME/.Xauthority-c, $HOME/.Xauthority-n and $HOME/.Xauthority-l behind, all size 0. Unless I delete them, startx refuses to work, too.

Despite what the above log claims, /etc/X11/xdm/Xsession isn't executed, I put a logger-line in the beginning, but nothing showed up in the logs.

I hope this wasn't too much information and anybody can help me finding the problem.

EDIT: kdm works fine by the way

Re: xdm trouble - xorg-xdm 1.0.1-1

This may seem completely unrelated, but it's not: do you use PPP or PPPOE to connect to the internet? -- ie. if you do an ifconfig, is there a pppX device?

Re: xdm trouble - xorg-xdm 1.0.1-1

Well, anyways, for the benefit of anyone else having this problem --- it's caused by a segfault bug in xdm. I submitted a bug report and patch to xorg's bugzilla, and the patch was already accepted and committed to CVS, so the next release of xdm should have this fixed.

In the meantime, here is a PKGBUILD and a patch that can be used to build an alternate xorg-xdm package with the bug fixed.  Note that you also need the file xdm.pam from ABS to compile the package.
