Some Ubuntu 22.04 "After Install" things that I did.
1. Install restricted media codecs to play various kinds of audio/video media files
sudo apt install ubuntu-restricted-extras
2. Access the new screenshot tool that also includes screencasting.
Press the Print Screen Key to take the screenshot
3. Cleaning your system
Use the apt autoremove command to remove unneeded packages (Ones that are not required anymore).
sudo apt autoremove
4. Add AppImage support
In 22.04 AppImage applications won’t run even if you setting the "Allow Execution" file permission. To get them to run, you need to install the libfuse2 library which AppImage files need to run:
sudo apt install libfuse2
This is a quick and dirty post just to get the methods on "paper" before I forget.
