Bug description

Screen is black after being woken after lock.

Error message tells me to report this if it's reproducible, it is.

PS I use an old Mac, the error message says to press , on a mac it's

Steps to reproduce

Been happening consistently of late, maybe something to do with updates but I can't even begin to guess which.

FYI to whoever asked for this, hoping this might help, at least the Mac part.

Expected behavior

Graphic desktop with login screen

I'm facing this issue as well. I'm using an Acer Predator Helios Neo16 and it happens daily, upon every wake up from suspend. Here are the pastebin from the errors generated - cinnamon-screen one happens every time, cs-backup-locker happens sometimes.
The repeatable one: cinnamon-screen
The occasional one: cs-backup-locker

I've 15 error logs from cinnamon-screen and 6 from cs-backup-locker, since 2026-Fev-01, if needed.
