I do know this. This is why I need to port Martin's NoGUIApplication,
which has an internal message queue, to Lazarus,

I suppose with Linux, FPC (or Lazarus ? ) uses X11 as a message queue
provider. But I was not yet able to find out how to post a message into
the X11 queue (with a thread or another application) and capture this
message by an FPC "procedure ... message" construct. (with FPC/Lazarus
on Windows this does work fine using Windows messages)

If it does work with Linux/X1, I need to think how to make it work with
NoGUIApplication, as well. If it does not work in Linux, anyway, I don't
think I'll bother.
