Kubuntu relies on KDE session management to preserve open applications, window layouts, and running processes upon login. This functionality is managed through background components like ksmserver, which stores session details to create a seamless user experience. Restoring the previous session accelerates workflows by instantly returning to the state before shutdown or reboot.
Some users prefer a minimal environment and want no lingering processes or applications at login. An empty session avoids reopening windows or tasks from a previous session, enhancing control and reducing clutter on systems with limited resources or multiple user accounts.
By modifying user-level configuration through System Settings, KDE can load a clean environment each time. This setup helps maintain consistent performance and offers a fresh workspace without inherited windows or services.
Steps to configure session startup option for Kubuntu (KDE):
- Open System Settings from launcher.
- Click on Startup and Shutdown menu on the sidebar.
- Go to Desktop Session panel by clicking on the sidebar menu.
- Click on Start on an empty session radio button in the When logging in section to start KDE with an empty session.
- Click on the Apply button to save the configuration change.
