# https://krlmlr.github.io/integrating-xpra-with-screen/
#
# Requirements: xpra, xvfb, ratpoison, firejail
#
# Simpler design: simply run ratpoison using xpra
# xplex attach <session> # create a session if does not exit
# xplex detach <session>
#
# Complex design:
# xplex run    <session> <command>
# xplex attach <session>
# xplex detach <session>

# See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=863891
#PATH="/usr/lib/xorg:$PATH" xpra start-desktop :$XPLEX_DISPLAY --start-child=ratpoison

# Need to edit /etc/xpra/conf.d/55_server_x11.conf and use the Old Xvfb option
#xpra start-desktop :$XPLEX_DISPLAY --start-child=ratpoison
#xpra attach        :$XPLEX_DISPLAY

# Needs newer xpra, see
# https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=864765
# Check with xpra --version
