With XUbuntu 18.10 (pretty fresh install) when locking the system the monitor is immediately suspended; pressing any key or mouse button doesn't wake it. Pressing CTRL + ALT + F7 finally wakes the monitor and the message below is presented:



This session is locked
You'll be redirected to the unlock
dialog automatically in a few seconds



enter image description here



then the lock screen appears and everything goes as expected.



Another solution is to type the password (while the monitor is still blank) then press ENTER which then wakes the monitor and also unlocks the session (if the password is correctly typed, of course).



I have these settings (Display Power Management on or off and/or Automatically lock the session activated or not make no difference):



enter image description hereenter image description here



The expected behavior with Display Power Management on and Automatically lock the session activated is:



  1. when locking the system first the monitor should be still on

  2. the lock window should be presented

  3. after 10 min the monitor should go black

  4. after 15 min the monitor should sleep

  5. after 60 min the monitor should switch off

  6. when pressing any key or mouse the monitor should switch on and the lock window be presented

What should I do in order to obtain the desired behavior? also I don't want to avoid the problem by using xscreensaver



UPDATE



The same behavior is no matter what I choose for Display Power Management and/or Automatically lock the session.



With Power Manager unchecked in Session and Startup (Screen Locker still checked) the behavior is the same. I guess it's a Screen Locker (light-locker) issue.

With XUbuntu 18.10 (pretty fresh install) when locking the system the monitor is immediately suspended; pressing any key or mouse button doesn't wake it. Pressing CTRL + ALT + F7 finally wakes the monitor and the message below is presented:



This session is locked
You'll be redirected to the unlock
dialog automatically in a few seconds



enter image description here



then the lock screen appears and everything goes as expected.



Another solution is to type the password (while the monitor is still blank) then press ENTER which then wakes the monitor and also unlocks the session (if the password is correctly typed, of course).



I have these settings (Display Power Management on or off and/or Automatically lock the session activated or not make no difference):



enter image description hereenter image description here



The expected behavior with Display Power Management on and Automatically lock the session activated is:



  1. when locking the system first the monitor should be still on

  2. the lock window should be presented

  3. after 10 min the monitor should go black

  4. after 15 min the monitor should sleep

  5. after 60 min the monitor should switch off

  6. when pressing any key or mouse the monitor should switch on and the lock window be presented

What should I do in order to obtain the desired behavior? also I don't want to avoid the problem by using xscreensaver



UPDATE



The same behavior is no matter what I choose for Display Power Management and/or Automatically lock the session.



With Power Manager unchecked in Session and Startup (Screen Locker still checked) the behavior is the same. I guess it's a Screen Locker (light-locker) issue.



This is the /var/log/syslog created when locking:

I do not have the actual solution of your problem yet but a temporary solution.



I found here a way to recover the situation without reboot the machine/LightDM.



In your tty1 Ctrl+Alt+F1, as root, type loginctl unlock-session [id], where [id] is the session id you get by running loginctl list-sessions.



If it doesn't work with the first ID, try with the other session IDs of your user account.



Try this as well.



sudo service lightdm restart
