I have an external monitor with 2 HDMI ports. When I step away from the computer, I lock the screen so my cat doesn’t mess stuff up when she rolls on the keyboard.
The problem is - the screen almost immediately goes black, and then my screen switches to my other computer, so I have to switch my monitor manually to go back to Unity. It’s very annoying. I’ve looked in System Settings, Tweak, and Unity-Tweak (why so many places?) but nothing seems to change this behavior. Help!
So, after a few days, it spontaneously started working. I’m not going to complain.
It turns out it wasn’t fixed, just works sporadically. I’ve discovered that I often hit an extra return key. So When I enter super+L followed by a return, it always works correctly. When I enter super+L and no key, or any other key, it will hibernate. Everything else works great, I can remember to hit enter when I lock the screen. But I think it shows the config is wrong somewhere.
I would guess you have “screen off with inactive for…” set to zero.
And the extra wakes the PC up immediately.
Can control the automatic input switching in most monitors.
The configuration for suspend or hibernate is systemd stuff I believe.
Yes, why are there power settings in “Brightness & Lock”.
Suspend/resume & hibernate are a lottery with linux. You’re lucky it works at all.
