# rdesktop
#
# rdesktop screen script for the linux terminal server project.
# This script lives in the /opt/ltsp/i386/etc/screen.d directory
#
# Call it through lts.conf with the `SCREEN_xx = rdesktop` option.
#
# You can pass options to rdesktop 2 different ways.
#
#   1)  Place all of the options you want after the 'rdesktop' setting
#       on the screen_script.
#
#       For example:
#
#           SCREEN_01   = rdesktop -u jam w2kserver.ltsp.org
#
#
#   2)  Place the rdesktop options in the RDP_OPTIONS option
#       and the name or IP address of the rdp server in
#       the RDP_SERVER option.
#
#       For example:
#
#           RDP_OPTIONS	 = "-f -u jam"
#           RDP_SERVER   = w2kserver.ltsp.org
#           SCREEN_01    = rdesktop
