Xsession.options - configuration options for Xsession(5)
/etc/X11/Xsession.options contains a set of flags that determine some
of the behavior of the Xsession(5) Bourne shell (sh(1)) script. See
the Xsession(5) manpage for further information.
Xsession.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. Options are
enabled by simply placing them in the file; they are disabled by
prefixing the option name with ‘no-’.
Available options are:
If the ‘failsafe’ argument is passed to the Xsession script, an
emergency X session is invoked, consisting of only an
x-terminal-emulator(1) in the upper-left hand corner of the
screen. No window manager is started. If an
x-terminal-emulator program is not available, the session exits
If users have a file called .Xresources in their home
directories, these resources will be merged with the default X
resources when they log in.
If users have an executable file called .xsession in their home
directories, it can be used as the startup program for the X
session (see Xsession(5)). If the file is present but not
executable, it may still be used, but is assumed to be a Bourne
shell script, and executed with sh(1).
If the dbus package is installed, the session bus will be
activated at X session launch.
If the ssh-agent(1) program is available and no agent process
appears to be running already, the X session will be invoked by
exec’ing ssh-agent with the startup command, instead of the
startup command directly.
All of the above options are enabled by default. Additional options
may be supported by the local administrator. Xsession(5) describes how
this is accomplished.
Stephen Early, Mark Eichin, and Branden Robinson developed Debian’s X
session handling scripts. Branden Robinson wrote this manual page.
