Public bug reported:
My laptop has been continuously upgraded (sometimes during development
cycles, sometimes only after release) since Ubuntu 10.04.
After upgrade to 17.10, I initially used wayland, but ran into some
problem with VT switching which led me to switch to X.
Upon switching to X, the default session option I'm given by gdm is
gnome-flashback-session, running compiz by default.
This was a terrible experience, so I then purged compiz (knowing that it
is no longer the supported wm for Ubuntu in 17.10). Launching the
session again, I get gnome-flashback-session running metacity.
This is also a terrible experience, and AIUI not the experience users
are expected to have by default. I am told that there is supposed to be
an 'Ubuntu on X' session which should be the default.
I think the upgrade needs to try harder to ensure the correct session is
used by default on upgrade. I don't believe gnome-flashback is
something I ever manually configured; it is marked as 'manually
installed' on my system, probably due to historic bugs in update-manager
marking all packages as manually installed. I think either gdm should
take this into account and deprioritize gnome-flashback as a session
option in the absence of explicit configuration, or update-manager
itself should take steps to ensure the package is removed on upgrade if
it's not meant to be there.
