# 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.
