[Daniel van Vugt (vanvugt)]

Thanks. That's not the problem...

Maybe some app is inhibiting the lock screen. Is it any different if you select 'Ubuntu on Wayland' from the login screen?

[Byron (byron-goodman)]

Wayland won't launch.

[Byron (byron-goodman)]

No crash files for Wayland.

[Daniel van Vugt (vanvugt)]

Please try disabling Bluetooth and/or other peripherals. Does that allow the lock screen to work?

I'm reminded of bug 1823076.

[Byron (byron-goodman)]

No, but I did do a dconf -f, and that at least lets me do it manually now. It will not lock automatically.

Of course, it reset everything, which as introduced others problems.

Question, what call is exposed to applications to get to determine DPI?

I am having scaling issues in Maple 2017.3 and Maple 2020. If I use Gnome (default) it works fine.

I am unable to get Wayland up.

[Daniel van Vugt (vanvugt)]

DPI is toolkit-specific and I won't go further into that because it is off-topic. Please open a separate bug for that.

[Daniel van Vugt (vanvugt)]

In comment #7 I meant please disable Bluetooth, Wifi, and unplug all USB devices. Does that allow the system to sleep? If so then please reintroduce them individually to find out which is the problem.

[Byron (byron-goodman)]

Done, didn't fix it.

[Daniel van Vugt (vanvugt)]

I've seen a few comments from people finding that their gnome-shell process crashes when it tries to lock the screen. And that means the screen never locks. So please follow these instructions:
