#!/bin/sh## This is SORT OF LIKE an X session, but not quite. You get a command as the# first argument (it could be multiple words, so run it with "eval"). As a# special case, the command can be:# default - Run the appropriate Xclients startup (see the code below)# custom - Run ~/.xsession and if that's not available run 'default'## (Note that other arguments could also follow, but only the command one is# right now relevant and supported)## The output is ALREADY redirected to .xsession-errors in GDM. This way# .xsession-errors actually gets more output such as if the PreSession script# is failing. This also prevents DoS attacks if some app in the users session# can be prodded to dump lots of stuff on the stdout/stderr. We wish to be# robust don't we? In case you wish to use an existing script for other DM's,# you can just not redirect when GDMSESSION is set. GDMSESSION will always# be set from gdm.## Also note that this is not run as a login shell, this is just executed.# This is why we source the profile files below.## based on:# $XConsortium: Xsession /main/10 1995/12/18 18:21:28 gildea $command="$@"# this will go into the .xsession-errors along with all other echo's# good for debugging where things went wrongecho "$0: Beginning session setup..."# First read /etc/profile and .profiletest -f /etc/profile && . /etc/profiletest -f "$HOME/.profile" && .
