These are good suggestions, but it seems that xsecurelock still can't provide a workaround for the bug where the screen doesn't lock if a popup menu happens to be open or the pointer is grabbed in any other way [0]. I couldn't find any good way to fix this and the only suggested workaround seems to be to switch to Wayland. I've switched on all of my machines (for this and for other reasons) but please make sure you know the details of this if you still use Xorg.
