In spite of setting auto-login in the Xubuntu settings (XFCE/System/Users and Groups) I have to login each time when I start up the computer. How can this be changed?
Type in a terminal:
sudo nano /etc/lightdm/lightdm.conf
sudo mousepad /etc/lightdm/lightdm.conf
(depending which text editor you want to use)
Add these lines to the file:
You could use e.g. file /etc/lightdm/lightdm.conf.d/autologin-xubuntu.conf, instead, but then you should make sure settings in another file in that directory or in file /etc/lightdm/lightdm.conf do not override it.
To remove password on resume, right-click the system tray power icon then Preferences. This brings up the XFCE power manager (Alternatively you can navigate to XFCE/Settings/Settings Manager/Power Manager). Click Extended in the left pane. Uncheck Lock screen when going for suspend/hibernate.
The last place is XFCE/System/Users and Groups. If it's set "Password: Asked on login" you can change it, and thereafter, if you logout or switch user, you can get back without entering password.
