[FFe] Enable gnome-fallback by default for LTSP Setups

[Jonathan Carter]

In Ubuntu 12.10, Unity does no direct rendering which means that all graphics processing takes place on the server on LTSP.

This has a huge negative impact on server performance to the point where it renders terminals unusable.

We should probably change the default desktop environment to gnome-fallback when LTSP is selected from the installer. Users who enable diskless fat clients will still be able to make Unity the default.

This also affects the package: edubuntu-netboot

Approving the FFe for this. The change will need to be documented in the release notes/announcement for Edubuntu and we may have to update some screenshots on the online documentation. Though as it stands, we don't have any so there's no immediate action needed.

I tested the change, gnome-classic didn't seem to be too reliable in my VM so I went with gnome-fallback (metacity based) instead, so far it looks like it's working, so a big improvement from what we had with unity regardless.

This bug was fixed in the package edubuntu-live - 12.10.9

---------------
edubuntu-live (12.10.9) quantal; urgency=low

  * Rebuild hoping that Launchpad won't strip the translations this time.
  * Update translations.
  * Change default session for LTSP from Unity to gnome-fallback.
    This is done as Unity isn't usable since unity-2d was deprecated.
    gnome-classic doesn't seem to be really reliable either, so
    gnome-fallback will be used as the default for now.
    It's still possible to change the desktop environment at login time on the
    thin client and for all thin clients in /var/lib/tftpboot/*/i386/lts.conf
    (LP: #1055635)
  * Also add a Conflict against unity-lens-shopping as it's considered
    inappropriate for Edubuntu's target audience. (LP: #1055705)
