Autologin

To configure a user to be automatically logged into the Desktop at system startup, use the following Hiera keys:

• desktop::autologin_enable: enable/disable autologin
• desktop::autologin_user: user account who should be looged in

Example:

desktop::autologin_enable: true
desktop::autologin_user: 'proton'

This is only implemented for gdm (default) and not yet for lightdm (rarely used at PSI)
