Red Hat Bugzilla – Bug 55826
Cannot use my RH box as an Xterminal anymore with KDM 3.0.0
Last modified: 2007-04-18 12:38:04 EDT
Description of Problem:
I cannot use My RedHat 7.2 box as an Xterminal (It worked with 7.1)
Just modify the files as mentionned below (My machine is called Lorient):
[ted@lorient /etc]$ diff inittab inittab.org
< x1:5:respawn:/etc/X11/prefdm -nodaemon
< x2:5:respawn:/usr/X11R6/bin/X -indirect lorient
> x:5:respawn:/etc/X11/prefdm -nodaemon
[ted@lorient xdm]$ diff Xaccess Xaccess.org
< * #any host can get a login window
> # * #any host can get a login window
< #* CHOOSER BROADCAST #any indirect host can get a chooser
> * CHOOSER BROADCAST #any indirect host can get a chooser
< %hostlist lorient brest toulon plnpc
> #%hostlist host-a host-b
< * CHOOSER %hostlist #
> #* CHOOSER %hostlist #
[ted@lorient xdm]$ diff xdm-config xdm-config.org
< ! DisplayManager.requestPort: 0
> DisplayManager.requestPort: 0
[ted@lorient xdm]$ diff Xservers Xservers.org
< #:0 local /usr/X11R6/bin/X
> :0 local /usr/X11R6/bin/X
I do not use Gdm but Kdm:
[ted@lorient sysconfig]$ more desktop
Grey screen. I do not get the XDMCP chooser window.
A grey screen WITH the XDMCP chooser window, where I can choose among 4
machines: Brest, Lorient, Toulon and Plnpc
I suspect a security problem but I don't know what has been changed between
7.1 and 7.2 in this respect.
I replaced /ec/X11/prefdm by /usr/X11R6/bin/xdm in inittab and it worked
From that I discovered that KDE 2.2 introduced a new kdmrc file
(/etc/kde/kdm/kdmrc), so now I am sure it has something to do with KDM
I tried to modify the kdmrc file to obtain what I wanted but without success.
I don't know what to do now.
I don't consider this to be a bug, but rather a misconfiguration issue.
xdm/kdm/gdm all work fine for me in my test environment. If you need
help configuring xdm/kdm/gdm and XDMCP, etc. please subscribe to the
firstname.lastname@example.org mailing list, or one of the Red Hat mailing lists.
There is also an XDMCP-HOWTO which you might find helpful.
Hope this helps.
I had finally succeeded in fixing this with RedHat 7.2 and KDE 2.2.2
Since then, I replaced KDE 2.2.2 by KDE 3.0.0 (a new kderc file). I have also
installed RedHat 7.3 on an other machine and with the Xaccess, inittab... files
CORRECTLY configured for an XDMCP request (tested succesfully with KDE 2.2.2), I
end up, again, with a grey screen using KDM.
I modified kdmrc according to this. It is equivalent to what I did for KDE 2.2.2
(and it worked then....). Do you know what has been changed from KDE 2.2.2 to
KDE 3.0.0? Could you please help me to find the right flag to get XDMCP working
again? Thanks in advance
bash-2.05a# diff kdmrc kdmrc.org
Sorry, but bugzilla is not a technical support forum, it is a bug tracking
database. If you require assistance configuring XDMCP, KDE, KDM, or any
other issues, please use the mailing lists previously mentioned for
I am very much aware of the fact that bugzilla is not a technical forum but
considering that few months ago there was a bug in the redhat KDE RPMS (for
2.1.x if I recall correctly) that was disabling the XDMCP request whatever the
configuration was and considering that the changes in the configuration files I
did for KDE 3.0.0 (RH73) are EXACTLY the same than the ones I did for KDE 2.2.2,
I don't really know if the problem is : configuration or bug....
PS: If you want, I can open a bug report for RH7.3 and kdebase-3.0.0-12 (kdmrc
is in this package)
