+.TH tdm.options 5 "2003\-09\-18" "Debian Project"
+.SH NAME
+tdm.options \- configuration options for X display manager
+.SH DESCRIPTION
+.I /etc/trinity/tdm/tdm.options
+contains a set of flags that determine some of the behavior of the
+X display manager
+.BR tdm (1).
+.PP
+.I /etc/trinity/tdm/tdm.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 \(oqno\-\(cq
+prefix, or absent, it is disabled, otherwise it is considered enabled.
+.PP
+Available options are:
+.TP
+.B ignore\-nologin
+Normally, the contents of the /etc/nologin file will be displayed using
+.BR xmessage (1x)
+(if
+.B xmessage
+is available), and the user will be returned to the tdm login screen after
+the xmessage is dismissed. If this option is enabled, tdm starts a session
+as usual (after the xmessage is dismissed, if xmessage is available).
+.TP
+.B restart\-on\-upgrade
+Enable this option with caution on \(oqproduction\(cq machines; it causes
+the tdm 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 tdm
+causes immediate termination of any sessions it manages; in some situations
+this could be an unwelcome surprise (for instance, for remote tdm 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 tdm's executable on the
+file system has no effect on the copy of tdm in memory). The tdm
+pre\-removal script checks to see if the tdm process has any children; if
+it does, it is possible that someone's session would be killed by stopping
+tdm, so a warning is issued and an opportunity to abort the upgrade of tdm
+is provided. If this option is disabled (the Debian default), tdm will be
+not be stopped or started during an install or upgrade; the administrator
+will have to do so by hand (with \(oq/etc/init.d/tdm restart\(cq, or by
+rebooting the system) before the newly installed tdm binary is used.
+.TP
+.B use\-sessreg
+If this option is enabled (the Debian default), the sessreg program will be
+invoked to register X sessions managed by tdm in the utmp and wtmp files.
+Otherwise, it is not, and the utmp and wtmp files will have no record of
+tdm sessions.
+.PP
+Users of older versions of the Debian system should note that the
+\(oqrun\-xconsole\(cq option has been removed. Shell scripts named
+.I /etc/trinity/tdm/Xsetup
+and
+.I /etc/trinity/tdm/Xreset
+can be edited to disable or modify the running of xconsole on the tdm
+greeter screen; see the
+.B tdm
+manual page for more information.
