X11 without a desktop

X11 without a desktop

[Gary Thomas]

I'm running a system roughly based on core-image-sato except
that I've disabled the matchbox desktop (I only have a single
application).  Some things still seem to want the desktop
to be in place though, in particular I don't get a popup
keyboard on my touch screen until I see this message:
   Timeout waiting for org.matchbox_project.desktop.Loaded

The problem is that this timeout is quite long - maybe a minute?

How can I fully disable this or adjust the timeout to be shorter?

Thanks for any pointers

That's the matchbox-keyboard init script which waits for the desktop
to say it's loaded, easily patched out (the intention was to serialise
the final stages of the boot so the desktop appeared quickly and then
the keyboard loaded in the background).

I found this:
    if [ "$CMD" ]; then
       # Delay to make sure the window manager is active
       # by waiting for the desktop to say its finished loading
       dbus-wait org.matchbox_project.desktop Loaded
       exec $CMD
   fi

Can I safely just disable the dbus-wait or do I need something else
there, e.g. sleep for a few seconds, ...?  Maybe I should patch dbus-wait
(which you, Ross, wrote) to be able to specify the timeout?

You can safely disable that block.  Patches welcome for dbus-wait, I
wrote it a *long* time ago.

OK, I'll let you know what I come up with.

BTW, 5 years *is* a long time in internet years, but not so long
for some of us "grey beards" :-)

Thanks
