On Debian 13 Trixie with older Plasma I had a padlock icon in the tray area in the bottom-right corner which locked the session using single click. I am unable to find it now inside KDE Neon:
Operating System: KDE neon User Edition
KDE Plasma Version: 6.6.1
KDE Frameworks Version: 6.23.0
Qt Version: 6.10.2
Kernel Version: 6.17.0-14-generic (64-bit)
Graphics Platform: Wayland
How can I add it?
Win. + L can be used to lock the session, but it is often faster to just aim and click.
Thanks, indeed. Somehow I thought the widgets are meant for a desktop, not for a tray panel.
So this worked, mouse right click the panel in a empty spot, Add or Manage Widgets, search for “lock”. Newly added button can then be configured to show:
restart
shutdown
logout
sleep
