NAME
Xsession.options - configuration options for Xsession(5)
DESCRIPTION
/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. If an option is present
with the "no-" prefix, or absent, it is disabled, otherwise it is
considered enabled.
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 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
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-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.
use-session-dbus
Starts up a D-BUS session bus for the display and sets
environment variables so that applications can connect to it,
using dbus-session(1).
xrdb-use-cpp
Invoke xrdb(1) with the -cpp option, to make it use cpp(1) when
processing resource files.
Additional options may be supported by the local administrator. See
Xsession(5) for how this is accomplished.
