I have Xfce-based Ubuntu Studio 18.10. I installed Cinnamon by running
sudo apt-get install cinnamon-desktop-environment
Now, how do I switch between xfce and cinnamon at log-in?
Where is that option? I don't see the option the way it appears in Ubuntu.
There's no rule that all distributions must have exactly the same way to show log-in options.
For example, both Lubuntu 18.04 and Xubuntu 18.04 have that option in their panels. In the image below, I have the panel on top, and clicking on the appropriate icon shows me my log-in options:
Lubuntu 18.10 (which has LXQt as its desktop environment), looks like this:
Whereas Kubuntu 19.04 has the option in the lower left corner:
If you still don't see any such icon to click on, please edit your question to post the output of ls /usr/share/xsessions.
