Evaluation of Xpra under VirtualBox without dealing with docker containers:

Two shells in parallel (1. before 2.):

  1. ssh shell to VB:
  • cd && rm -R .xpra && xpra start :100 --start-child=xterm --exit-with-children
Entering daemon mode; any further errors will be reported to:
  /home/vagrant/.xpra/:100.log
  • xpra list:
Found the following xpra sessions:
	LIVE session at :100
  1. GUI login & startx:
  • perfect OpenGL performance: glxgears -info -fullscreen directly in xterm:

Xpra / Docker:

  • build docker-desktop following https://github.com/rogaha/docker-desktop
  • Run docker-desktop:
docker run -e USER --rm -it -a stdin -a stdout -a stderr  -v /etc/passwd:/etc/passwd:ro \
 -v /etc/shadow:/etc/shadow:ro -v /etc/group:/etc/group:ro -v /etc/localtime:/etc/localtime:ro \
 -v /etc/sudoers:/etc/sudoers:ro -v /etc/sudoers.d/:/etc/sudoers.d/:ro \
 -v /tmp/:/tmp/:rw -v /home/:/home/:rw docker-desktop sudo su $USER
  • testing the start of Xpra in that container:
XPRA_SOCKET_HOSTNAME=myhostname xpra --socket-dir=$HOME/.xpra start :100 --start-child=xterm --exit-with-children

Note that setting a different socket-dir (e.g. --socket-dir=/tmp/.xpra) still leads to the creation of $HOME/.xpra with Xorg.:ID.log and run-xpra.

In any case xpra terminates & cleans-up shortly afterwards... ps aux shows a bunch of zombies (like [xpra] <defunct>) :(

What is wrong?
