NAME
Xsession.options, Xsession.options.d - configuration options for Xsession(5)
DESCRIPTION
/etc/X11/Xsession.options and /etc/X11/Xsession.options.d/*.conf contain options that determine some of
the behavior of the Xsession(5) Bourne shell (sh(1)) script. See the Xsession(5) manpage for further
information.
These configuration files 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-’.
Options are read from /etc/X11/Xsession.options, followed by /etc/X11/Xsession.options.d/*.conf in sorted
order; later occurrences of an option (with or without the ‘no-’ prefix) take precedence over earlier
occurrences.
Available options are:
allow-failsafe
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
immediately.
allow-user-resources
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.
allow-user-xsession
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).
use-session-dbus
If the dbus package is installed, the session bus will be activated at X session launch.
use-ssh-agent
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.
