Hello & Greetings, Genymobile. The only reason why I am asking questions is because I have a negative issue. To start with, I explored about Android's Developer connectivity, it's Debug Bridge. And I use Windows 11. I wanted to use the forced experimental desktop from an Android phone to operate on a computer. So I used your well-known & trusted program, Scrcpy with ADB, to link both wired and wirelessly. Successfully, I accessed the experimental destop. :-) , But I cannot control it with my mouse cursor! <:-( . I was only able to operate with the keyboard as normal, but sadly, I was not able to do almost anything without the cursor control. I would thankfully appreciate the instructions that you provide me. Thanks.

By the way, even though I had to install some more applications and had to type in some terminal code for experimental desktop to work, Scrcpy still runs in it's normal mirroring technology. But I mainly need help to fix my mouse console that refuses to work. Thanks :-)

What if you pass --mouse=uhid? https://github.com/Genymobile/scrcpy/blob/master/doc/mouse.md#uhid

I entered it in, but the cursor was in the phone's screen instead of the computer. Like this: The cursor was trapped in the phone screen, but I wasn't able to control the forced experimental desktop. Sorry to say.

Yes, I thought this was what you wanted.

If you don't do that, then the cursor "stays" on the computer and you can click. So what do you want to achieve?

I wasn't using screen mirroring, but was using the 'Experimental Desktop' mode on 'Android Developer settings'. So the thing is that the phone sends out it's desktop view of itself on another screen, while it's on something else.

Oh, ok. The UHID keyboard behaves (or should behave) as if you plugged a physical keyboard on your device. What happens if you plug/connect a physical keyboard?

I don't know if the UHID mouse can be configured to work on a separate virtual screen.

Wow. Thank you so much for helping me out! :-)

I think it's impossible. Presume the "official" virtual mouses work on virtual displays, it uses InputManagerGlobal.addUniqueIdAssociation and InputManagerInternal.setVirtualMousePointerDisplayId

I tried InputManagerGlobal.addUniqueIdAssociation, it only causes our UHID mouse to stop functioning. InputManagerInternal.setVirtualMousePointerDisplayId is not exposed.

Anyway, Android only has one mouse cursor so making it work on multiple displays is also impossible.

Thank you for your investigations.

@onyhen What's the problem with the normal mouse mode (when you don't pass --mouse=hid)? You should still be able to click, can't you?
