  • Welcome!

    I'll get straight to the point.

    When I started Pop!_Planet, I launched it because I saw a need for a centralized community for Pop!_OS. To be frank, I never expected the level of popularity it has achieved. Over the last year, we have gone from under 50 users, to almost 400 users. That's awesome! However... it also comes with a downside. We are rapidly running out of disk space on our server, and the bandwidth costs go up every month.

    Pop!_Planet is not affiliated with System76 in any way, and is funded completely out of pocket. From day one, I said that I'd never use on-site ads (I hate them as much as you do), so the only monetization we get is through donations. Right now, the donations we receive don't even cover our overhead.

    I know that most users will ignore this message, and that's ok. However, if even a few of our users are willing and able to donate a few dollars to help offset our expenses, it would be greatly appreciated.

    Support Pop!_Planet

    Thank you for your time,

Solved Screen will not lock

I have a Lemur Pro. It's an amazing machine that has worked flawlessly since the day it arrived, even after upgrading to 20.04 - until last week.

The screen no longer locks after it goes blank or after system suspend. I'm also unable to lock the screen manually.

My Power and Screen Lock settings have not changed. (See below)

Since I regularly perform system updates, and new software is continuously introduced, I'm unsure how to best go about troubleshooting this issue.

These are the Gnome extensions I have installed. I've deactivated all of the Manually installed extensions with no success.

I would appreciate any suggestions or insights related to this problem. Happy to jump into Discord to chat in real-time.

If you can use the pastebin to post the output of journalctl -f and dsmeg right around the time it fails to suspend, we'll take a look. Meanwhile, what happens if you enter systemctl suspend into a terminal?
Being a System76 machine, opening a support ticket might be a faster way to get help.

Thanks for the suggestion, @derpOmattic. I found this in the journal:

Jun 18 12:50:00 zoboomafoo gnome-shell[2284]: Screen lock is locked down, not locking

Which led me to this search result:

Used dconf-editor and went to org.gnome.desktop
Saw that disable-lock-screen was enabled, and disabled it from there.
I used dconf-editor to toggle disable-lock-screen. I have no idea how that flag became set, but it's fixed.
