I want to quickly switch user accounts with a shortcut combination, something similar how a session can be ended by
Ctrl + Alt + Del or locking the screen by
Ctrl + Alt + L ?
(I'm using Unity, 11.10)
You can open the settings for shortcuts: System -> Preferences -> Keyboard Shortcuts and add a custom shortcut to start the gdmflexiserver. After that you can switch with the shortcuts strg+alt+F7 and strg+alt+F8
