Bug Description

Hello, I use i3lock to lock my screen. systemd starts gnome-screensaver when I suspend my laptop because I haven't figured out how to turn that off yet.

Most of the time this is no big deal, I just have to unlock twice the five or six times a year I suspend my laptop.

Today, however, I couldn't actually interact with the gnome-screensaver lock screen:

- I resumed my laptop
- I unlocked the already-running i3lock
- The gnome-screensaver was running, showed the correct time in the center of the 'titlebar', showed my user name in the right side of the titlebar, and the mouse moved around fine.
- I blindly typed my password and hit enter
- The mouse pointer turned to a spinner for 20~40 seconds
- The mouse pointer could move around, but couldn't interact with any screen elements
- ctrl+alt+f1 etc worked fine to change virtual consoles

I was only able to use my X11 session after manually killing the gnome-screensaver process from a shell.

Thanks

Hmm. The process I killed was most definitely gnome-screensaver.

It might have been running in an LXD instance. This is strange.
