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: +# failsafe - Run an xterm only +# 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.
