I've just upgraded to 11.10 beta using update-manager and all went well.

However, the install process leaves installed default packages from the previous version that I no longer want (gdm, evolution etc.)

I've generated a list of additional packages I have installed via a method similar to

However my list contains lots of packages I installed and do want to keep - is there an easy way to just remove the deprecated default packages?

You should be able to just run:

sudo apt-get autoremove

to remove packages that are no longer needed. You can also use the "Local or Obsolete" filter in Synaptic at "Status" section.

Probably not going to work, as packages are marked as manually installed upon installation, so things like Evolution wouldn't show up there just because dependencies of ubuntu-desktop (or whatever package pulled it in) have changed. – htorque Sep 10 '11 at 18:03
@htorque: you might be right :P. Some packages though did show up there (as autoremovable) when I upgraded :). – RolandiXor Sep 10 '11 at 18:11
