The actual installation of the latest ISO-9660 image on a System76
Gazelle Pro went more or less smoothly.  Thanks for that!

There were the following small nits:
- the trackpad was not recognized by the graphical installer
  (a USB mouse worked, but so did navigating using keys only)
- no timezones available that weren't tied to a locale
- installer log messages (ctrl-alt-f4) have a lot of ^M
It was able to work with the unusual disk setup that chokes Ubuntu
Desktop's installer.
On the down side, is that sleep/hibernate is not working.  I've got
XFCE4 for a DE.
When I go to the menu XFCE -> Power Manager and, for example, set the
laptop lid to trigger "suspend" nothing happens.  The system continues
to run as normal and the screen stays lit.  Same for then I set the
laptop lid to trigger "hibernate"
When I go to the menu XFCE -> Power Manager and set the sleep button to
"suspend" the sleep button gives every indication of having suspended
the system.  However, when I try to wake it up the machine seems to turn
itself off and then on again two times before doing a cold boot.
    # swapon -s
    Filename        Type          Size    Used    Priority
    /dev/md1p1      partition     8778748 0       -1
So the sleep button can activate "suspend" but instead of sleeping it
actually shuts the machine down in some way.  What must I set or change
to use the "suspend" and/or "hibernate" capabilities?  Either would be
fine at this stage.
