Unfortunately I still can't reproduce the bug (on 23.04) using those steps.

[ Original report ] (initially reported as a comment on bug #1965085, and split into a separate bug report) After I lock my screen and let it blank, moving the mouse or pressing any key on the keyboard won't wake it up. The only reliable workaround I've found is to press Ctrl+Alt+F1. That's on a fully up-to-date jammy, my hardware is an Intel NUC with a single Samsung monitor connected with a standard HDMI cable. This is a regression that started happening yesterday (2022-04-05) if I can remember correctly (I do apply pending updates at least once daily).
