Why do I get a black window when creating a whole desktop on remote?
https://xpra.org/trac/wiki/Usage#Forwardingawholedesktop
Xpra normally forwards just the windows of the application you are
interested in. If you want to forward a full desktop instead
(including its start menu, background, task bar, etc...) use the
"start-desktop" mode:
xpra start-desktop --start-child=fluxbox
Notes: you can start a window manager of your choice (here fluxbox) or
none at all..
I have two Lubuntu 18.04 laptops. I want to start a new session on one from the other and access it from the other
First start by running the window manager:

2019-03-12 19:43:05,014 Xpra X11 desktop server version 2.1.3-r17247 64-bit
2019-03-12 19:43:05,014 running on Linux Ubuntu 18.04 bionic
2019-03-12 19:43:05,015 enabled remote logging
2019-03-12 19:43:05,019 Attached to ssh/t@olive/:400 (press Control-C to detach)
2019-03-12 19:43:38,621 window-close event on desktop or shadow window, disconnecting
2019-03-12 19:43:38,623 Error: printing disabled:
2019-03-12 19:43:38,625 No module named cups
But it gives a completely black window. What shall I do?
If I start the GUI session (instead of window manager) on remote, by xpra start-desktop ssh:t@olive:400 --start-child=lxsession
, it doesn't give me start menu, background, task bar, etc), but a very vague login small window. After I login, the same black window as above.
Thanks.
