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?
This worked for me, type in a terminal:
sudo nano /etc/lightdm/lightdm.conf.d/10-xubuntu.conf
sudo mousepad /etc/lightdm/lightdm.conf.d/10-xubuntu.conf
(depending which text editor you want to use)
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 that but it's really not necessary and this did not work for me.
