I know there's a lot of similar questions, but this is why it's not a duplicate:
- I've checked most of the questions
- I need to control the device from Linux
- I don't need shared screen
I'd like to see something similar to Synergy for multiple computers (https://symless.com/synergy). It behaves like an additional screen, so you can use one mouse and see it moving on Windows laptop even it's connected to Linux PC.
Is there any app that simulates Android device as an additional screen so you can use your mouse and keyboard and see the mouse moving on your Android? I prefer not to use any apps that grabs the phone screen and sends it back to the PC, because it's rather slow. I keep my device close to the laptop so this is just an unnecessary feature.
