Issue

I've recently started seeing an issue where, when I lock the screen and walk away from my laptop, after some period of time cinnamon-screensaver will crash and unlock the screen. When I come back, the screen is unlocked as if I had never locked it, and I see the following in dmesg:

[ 1138.269741] cinnamon-screen[3894]: segfault at 6174617a ip 00007f7551293160 sp 00007ffec53e10f8 error 4 in libgobject-2.0.so.0.6400.6[7f7551265000+36000]

And I am no longer able to lock the screen again.

Restarting lightdm manually fixes the issue and makes it so I can lock the screen again, but having the screen randomly unlock when I'm away from my computer is a massive security issue.

Steps to reproduce

  1. Lock screen
  2. Wait for cinnamon-screensaver to crash

Expected behaviour

cinnamon-screensaver doesn't crash and the screen remains locked.

Not sure if this is related to #392?

Quite a bit has changed since the version you're running - I'd suggest trying the latest version.

Thanks. I'm running Linux Mint 20, is there a way to upgrade cinnamon-screensaver without upgrading the Linux Mint version?
