Because of the Raspberry Pi's limited power, getting an answer from displayfd
might take more than the ten seconds specified as the standard timeout. In order to change this, you can start xpra like this:
xpra start --env=XPRA_DISPLAY_FD_TIMEOUT=30 ...
Alternatively, always specify a display when use the xpra start
subcommand.
