[Vm-dev] HostWindowPlugin for Linux

Tim mentioned that the HostWindowPlugin is missing in the plugins.int for
all Linux builds.
Is there a particular reason why? Should we add it?

sudo by running a trivial test program in the shell script; all it does is
try changing a thread priority and returns whether it worked or not.

Unfortunately that doesn’t work when using xrdp for your remote display.
It’s not even a strictly squeak issue - some googling will reveal a
depressingly long list of problems to do with the same error. The Raspbian
kernel; has no problems at all with squeak when using a direct display. It
doesn’t have this particular problem with vnc - but it *does* have a fatal
problem with trying to use the composition input window calls. Again, not a
specifically squeak, raspbian nor ARM issue but a generic bit of nastiness

as we are about to release Squeak 5.1 very soon.
As long as it’s made from the very latest source Eliot put out today it
will be ok. *Except* I note that the HostWindowPlugin is missing from the
plugins/int file in build.linuxARMv6/squeak.cog.spur and in fact after a
quick look it is missing form all the linux related build directories that
I checked. Whilst the plugin is not complete it does provide support for
title and size aspects and so I’d recommend including it.
5.1 will be the basis of the next Pi Scratch release so I have several
millions of reasons to help getting it right...
