Version:           unspecified (using KDE 4.7.1) 
OS:                Linux

When selecting 'remote login' in kdm and moving the mouse above the
chooser window the X server restarts, showing the login screen again.

/var/log/everything.log showed:

Sep 12 11:28:21 (none) kdm: :0[1399]: Received unknown command 4 from
greeter

Reproducible: Always

Steps to Reproduce:
Start KDM
Select "remote login"
Move the mouse in the chooser window

Actual Results:  
X server/kdm restarts

Expected Results:  
selecting remote host possible

 I have the same issue:

...
Sep 25 09:35:26 kdm: :0[6496] error: Received unknown command 4 from greeter
Sep 25 09:35:26 kdm: :0[6496] debug: closed greeter for display :0

Sep 25 09:35:26 kdm: :0[6496] debug: starting greeter for display :0
....

So XDMCP is broken in KDE.

Even though I am still running kde-7.3, reverting to kde-base/kdm-4.6.5-r2

I have 2 systems affected. Both amd64 kubuntu 11.10 (KDE 4.7.3)

The error message from kdm_greet:
> Cannot load /usr/share/kde4/apps/kdm/faces/.default.face: No such file or directory
can be removed by choosing a default user image:
 (System Settings - Login Screen - Users - User images - User: default)

After setting a default image, I still get the kdm error:
> kdm: :1[4010]: Received unknown command 4 from greeter

FYI Gentoo has resolved this successfully by reverting kdm commit

This basically changes the logic back to as it was in kdm-4.6.5

Thanks for hint Andreas !
Revert seems to work for 4.8.0 too.

Is there anything going on with this? It still appears to be broken in
Kubuntu Oneiric. Has KDE actually been fixed, or are individual
distributions just doing reverts? I'm currently running KDE 4.7.4 but
will upgrade to whatever ships with precise.

centralize interaction notification handling

that way we don't have to handle it all over the place (which we didn't,
which made the chooser dysfunctional).
