edit: Sadly this doesn’t prevent automatic screen shut off anyway for me - back to presentation mode it is.
That sounds like it would disable the screen going into power saving mode? Thank you for that, since that is another issue I have (also using presentation mode as a workaround)
The issue this thread is about would still exist after manually locking or standby resume.
To be clear about what my issue is: When coming back into a session that was locked for one reason or another, sometimes I get a black screen that has a working mouse cursor but shows nothing else. The mouse cursor even changes state, depending on where it is (pointer, caret, hand, resizer, etc.). Sometimes waiting a bit can resolve this by itself, sometimes it cannot.
