[winswitch] Render Without Attach

[matthew]

I would like to be able to run a GUI application within an Xpra session and
submit login credentials via the xdotool. For example, the application
would startup via a cron schedule and a subsequent cron job would submit
the login credentials.

Unfortunately, I am unable to force the application to render in an Xpra
session unless I interactively run "xpra attach" at least one time with X11
forwarding. Therefore, the interface is not available for the xdotool to
interact with.

Is there a way to achieve this kind of automation without an explicit "xpra
attach"?

Thank you in advance and thank you for developing and supporting Xpra.

Kindly,

Matt B
