For some reason, when I open my laptop and it wakes up, it no longer asks me for my user password (it used to). How do I troubleshoot this and enable password request upon wake?

Anything in syslog or dmesg around the time of the wakeup ? Can you paste it here or link it to pastebin ? – Robert Riedl Jan 20 '18 at 22:48

This happens intermittently for me on 16.04. Is it still always happening for you or just sometimes? – Chai T. Rex Jan 21 '18 at 00:59

You mention closing and opening lid for suspend/resume actions. What happens when you select **Suspend** from the menu and use power button to resume? – WinEunuuchs2Unix Jan 25 '18 at 00:45

Same behavior. It wakes up and I’m back at my desktop. – ffxsam Jan 25 '18 at 01:12

Check the value of
gsettings get org.gnome.desktop.screensaver ubuntu-lock-on-suspend
if it comes back with 'false' set this to 'true' with
gsettings set org.gnome.desktop.screensaver ubuntu-lock-on-suspend true
You can also do this with a GUI, using dconf-editor - navigate to 'org->gnome->desktop->screensaver->ubuntu-lock-on-suspend'

It's so because Automatic Suspend may be off.
Turning it on will solve the problem. Here is how:
- Go to Settings > Power.
- Click 'Automatic Suspend' option.
- Turn "When Idle" option on.
Done. Let me know if this solves your problem or not.

Nope, it was not off. And it's set to "when on battery", delay of 15 mins. There is no "when idle" option. (I'm on Ubuntu 17.10) – ffxsam Jan 27 '18 at 01:30

Step 1 is Screensaver installed?
The password when resuming from suspend is based on lock screen screen and lock screen is based upon screen saver. To check screen saver use apt list --installed | grep saver:
WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
gnome-screensaver/xenial,now 3.6.1-7ubuntu4 amd64 [installed]
If you don't see a screen saver above then use:
sudo apt install gnome-screensaver
Step 2 is lock screen enabled?
Lock screen needs to be enabled:
gsettings get org.gnome.desktop.lockdown disable-lock-screen
false
If result is true then use:
gsettings set org.gnome.desktop.lockdown disable-lock-screen false

Aha! Now we're onto something. Super+L does not lock the system as it should. And that key shortcut is defined properly. – ffxsam Jan 27 '18 at 01:55

Try `gsettings get org.gnome.desktop.lockdown disable-lock-screen` – WinEunuuchs2Unix Jan 27 '18 at 01:59

I just noticed I have this same issue: https://askubuntu.com/questions/986182/ubuntu-17-10-screen-lock-not-working-and-grey – ffxsam Jan 27 '18 at 02:02

That fixed it!! Thank you! I have no idea how that happened.. I certainly didn't set it. – ffxsam Jan 27 '18 at 02:04

Glad it works. Thanks for pointing out the similar problem, I copied a portion of the answer over there for them. – WinEunuuchs2Unix Jan 27 '18 at 02:06

Check the suspend logs at /var/log/pm-suspend.log
sudo nano /var/log/pm-suspend.log
Possible Solution 1:
Edit the file '/etc/systemd/logind.conf'
sudo nano /etc/systemd/logind.conf
Removed the # comment from the beginning of the line 'HandleLidSwitchDocked=ignore' and changed the value to be:
HandleLidSwitchDocked=suspend
Restart the systemd daemon with this command:
sudo restart systemd-logind
or, from 15.04 onwards:
sudo service systemd-logind restart

No such luck. And there is no `/var/log/pm-suspend.log`. It's not necessarily closing the lid that's the issue. Suspend in general doesn't require a password when waking up. – ffxsam Jan 26 '18 at 02:23
