I know it used to be possible to install several different flavours of Ubuntu into the same Ubuntu base. I could log out of flavour 1 and log back into Flavour 2, and so on I have forgotten how to do this :-( Please advise.

For testing I would use VirtualBox – nobody Nov 25 '20 at 15:09

Yes you can install multiple desktops on a base system.
The system I'm replying to you on is originally a artful (17.10) Ubuntu desktop install, on which I added lubuntu-desktop
, xubuntu-desktop
& ubuntu-mate-desktop
. It's been upgraded every six months (I don't remain on LTS or long-term-support releases).
I have since removed ubuntu-mate-desktop
(because of disk space issues; I used it least).
Take note:
- On adding the second desktop I would not expect any issues.
- On adding the third desktop there is a minor chance of issues.
- On adding the fourth desktop there is a substantial risk of issues.
- On adding the fifth desktop, issues are to be expected.
I installed my 4 (GNOME, XFCE, LXDE [now LXQt] & MATE) many times in different orders before I calculated the best order without issues, then formatted the system and installed them for real (and it's still running now, where I'm replying from).
I also wanted KDE (or kubuntu-desktop
) but decided that was too much, the problems got annoying.
It's not just the desktops, but also the order they are added.
The above is from my experience, as a multiple-desktop user for over a decade on Ubuntu (longer on Debian).

As you add more desktops, the issues becomes more severe. Once you have 3+ you'll find changes you make on one can have unintended consequences on others, esp. with the appearance (don't forget changes to a GTK desktop will likely impact all GTK desktops, likewise Qt impacting other Qt desktops) and you need to use themes/icons/etc in work in all... ie. You'll find you aren't changing display configs much once its working esp. if you have 4+ desktops. I didn't mention the busy & sometimes confusing menus etc.. I love it though; I can select in the morning how my PC will look for the day. – guiverc Mar 11 '23 at 11:12
You can install different desktops from the terminal e.g.
sudo apt install ubuntu-mate-desktop xubuntu-desktop
You can choose which one to use when you log in.

Problem was I had forgotten I had to get desktops from the terminal NOT from a mirror.:-( Thanks to everyone! – Brian Nov 26 '20 at 11:21
