That's really interesting.  However, most of our installations are
Debian X2GoServer but Windows X2GoClient.  Is that a non-starter for
libjpeg-turbo? Thanks - John

PS - Brian, may we trouble you to replace the subject (X2go-dev Digest)
with the actual thread subject when you reply? That would make it much
easier to sort through the piles of mailing list emails.  In my for
example, when busy, I only take the time to open emails with subjects
where I think I can help or learn something important.  Thanks - John
