tdm.options(5)

NAME
tdm.options - configuration options for X display manager

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

/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 ‘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 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).

restart-on-upgrade
    Enable this option with caution on ‘production’ 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 ‘/etc/init.d/tdm restart’, or by rebooting the system) before the newly installed tdm binary is used.

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.

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