Cannot reproduce on master Wayland, the screen just turns on again. Can reproduce on X
I think what happens is that the escape press turns the screen on, and then kscreenlocker sees the escape press and turns it off again

Is this about the *login* screen or the *lock* screen?
(In reply to Nate Graham from comment #4) > Is this about the *login* screen or the *lock* screen? I think it's the lock screen? Anyways it's the screen that appears after you hit CTRL-L, not the one that appears after you boot your computer, so it's the lock screen.
Thanks.
Adding the x11-only keyword
Closing as not worth fixing due to minor effect or esoteric nature, and a shift of focus away from X11. Thanks for understanding, folks!
