How can I switch from Ubuntu Cinnamon to default Ubuntu?
I have installed Ubuntu Cinnamon 22.04.3 LTS from the official ISO. However, I want to switch from Cinnamon flavor to "unflavored" Ubuntu. How do I do that? Just uninstalling the Cinnamon desktop environment? Or do I also have to install a new desktop environment?
Also, are there any other modifications in Ubuntu Cinnamon that I should change to get to default Ubuntu behavior?
To install Ubuntu (GNOME flavour) from within any other flavour, is essentially just a couple of commands:
sudo apt update
sudo apt install ubuntu-desktop^
This will install the task (note the caret ^) which pulls in all the necessary packages to allow you to login to the Ubuntu GNOME flavour.
You may get prompted with a few questions. For example, it will likely ask if you want to use GDM3 as the login manager – you do.
Once complete, you can reboot and choose the "Ubuntu" or "Ubuntu on Xorg" session at the login screen.
