Where I work just switching into a TTY would be enough to keep anyone out.

Whatever comes with GNOME/gdm.

I use i3 lock, scrot and imagemagik to make my lock screen a blurred version of my actual screen

Swaylock, but the one with effects. Using it to leave a blurred picture of the current screen without anything readable. Works well for two years now, is wayland only

Kscreenlocker because it came as default and I made it look identical to sddm

I just use XScreenSaver because I haven’t ever looked into changing it.

By screen locker, what do you mean exactly? Do you mean a setting that automatically locks your screen after a preset amount of time? If so, yes I do.

slock. i don’t really use anything else from the suckless people, but i like how minimal slock is

Whatever one comes with Manjaro KDE.

Because I don’t really care.

None currently, because I live with my family and if I wanted to hide anything from them (which I don’t), I could just switch to a tty, or log out. Most of my work is done in VSCodium or Vivaldi, which save their sessions, although I have considered doing one just in case.

None.

Why? Erm, living by myself I don’t need to lock myself out ;)

Waylock, because it keeps sway locked even if the screen locker crashes.

I’ve always used i3lock. I also made a script to randomly select a background. Plus the login password circle thing looks cool. Would definitely recommend.

SDDM 0.20 Wayland mode is awesome!

Physlock because it locks the other vts as well.
