#
# This is just a sample implementation of a slightly less primitive
# interface than xinit.  It looks for user .xinitrc and .xserverrc
# files, then system xinitrc and xserverrc files, else lets xinit choose
# its default.  The system xinitrc should probably do things like check
# for .Xresources files and merge them in, startup up a window manager,
# and pop a clock and serveral xterms.
#
# Site administrators are STRONGLY urged to write nicer versions.

# Rewritten for more reliable argument processing
# (c) 1999  John Latham, Dept. Computer Science, University Of Manchester, UK.
# email: jtl@cs.man.ac.uk

# This fixes certain bugs, e.g. if user has .xserverrc but still supplies the
# server as an argument. Same for client. Red Hat 6.2 startx looked like it was
# trying to fix this for the server, but didn't! Red hat 7.1 has reverted.

# Automatic choice of next available display by default added by John Latham
# on 19 October 1999.

# Minor fix 21 September 2000.

# August 2001: Merged in Red Hat 7.1 startx version -- see opening XConsortium
# comments above.

# August 2002: Put single quotes around server and client options, and start
# initx with an eval, so that quoted arguments containing spaces should work...
# These got missed out of /usr/X11R6/bin/startx, and were only added to
# CS dotfiles /usr/local/etc/bash_profiles/startx.linux !!
# Added to /usr/X11R6/bin/startx August 2004.

# October 2002: Merged in Red Hat 7.3 startx version -- see opening XConsortium
# comments above.

# August 2004: Merged in Fedora Core 2 startx version.

# November 2009: added unset of XDG_SESSION_COOKIE etc..

# ------------------

# November 2009: added these to make sound work!
