NAME

       kdm.options - configuration options for X display manager

DESCRIPTION

       /etc/kde4/kdm/kdm.options  contains  a  set of flags that determine some of the behavior of the X display
       manager kdm(1).

       /etc/kde4/kdm/kdm.options may contain comments, which begin with a hash mark and end at the next newline,
       just like comments in shell scripts.  The rest of the file consists of options  which  are  expressed  as
       words  separated  by  hyphens,  with  only  one  option per line.  If an option is present with the ‘no-’
       prefix, or absent, it is disabled, otherwise it is considered enabled.

       Available options are:

       ignore-nologin
              Normally, the contents of the /etc/nologin file will be displayed using xmessage(1x) (if  xmessage
              is  available),  and  the  user  will  be  returned  to the kdm login screen after the xmessage is
              dismissed.  If this option is enabled, kdm starts a  session  as  usual  (after  the  xmessage  is
              dismissed, if xmessage is available).

       restart-on-upgrade
              Enable  this  option with caution on ‘production’ machines; it causes the kdm daemon to be stopped
              and restarted on upgrade, even if  the  process  has  children  (which  means  it  is  managing  X
              sessions).   Typically  when  a package that contains a daemon is being installed or upgraded, its
              maintainer scripts stop a running daemon process before installing the new binary, and restart  it
              after  the  new binary is installed.  Stopping kdm causes immediate termination of any sessions it
              manages; in some situations this could be an unwelcome surprise  (for  instance,  for  remote  kdm
              users  who  had  no idea the administrator was performing system maintenance).  On the other hand,
              for machines that stay up for long periods of time, leaving the old daemon running can  be  a  bad
              idea  if  the new version has, for instance, a fix for a security vulnerability (overwriting kdm's
              executable on the file system has no effect on the copy of kdm in memory).   The  kdm  pre-removal
              script  checks  to  see  if  the  kdm  process  has  any children; if it does, it is possible that
              someone's session would be killed by stopping kdm, so a warning is issued and  an  opportunity  to
              abort  the  upgrade of kdm is provided.  If this option is disabled (the Debian default), kdm will
              be not be stopped or started during an install or upgrade; the administrator will have to do so by
              hand (with ‘/etc/init.d/kdm restart’, or by rebooting the system) before the newly  installed  kdm
              binary is used.

       Users of older versions of the Debian system should note that the ‘run-xconsole’ option has been removed.
       Shell  scripts named /etc/kde4/kdm/Xsetup and /etc/kde4/kdm/Xreset can be edited to disable or modify the
       running of xconsole on the kdm greeter screen; see the kdm manual page for more information.
