Question: sharing the virtual screen over via USB

[Hi-Angel]

From the documentation I can't quite get that, so before I'm gonna spend days digging into the code, I'd like to ask if such usecase is covered.

My usecase: I have a turned off phone with a broken display that I want to access for backup purposes. On my Linux desktop I want to create a virtual screen and then connect the phone USB-to-USB and make phone recognize my virtual screen as an external monitor. (note: I can't enable USB-debugging or anything, so e.g. tools like scrcpy won't work, it has to be something that Just Works™ as far as the phone side concerned)

Is it possible with EVDI? Mentioning basic steps would be appreciated though.

P.S.: sorry for asking on a bugtracker, but the project doesn't seem to have a matrix/IRC/mailing list…

I think this project only allows you to create virtual displays on the machine the kernel module is installed.
This module essentially creates a drawing surface the window manager sees as a monitor.
Other programs in user space can then copy the monitor contents and send them off to e.g a vnc connection or some kind of display device.

Does your phone have the evdi module loaded?
Do you have access to your phones shell? (adb not working?)

You may have better luck buying a usb c to hdmi/usb adapter and hope that it works.
Then plug in a regular monitor and mouse and keyboard.
If your phone is modern enough it should just work™️.

I see, okay, thank you!

Regarding adb — it requires to enable USB-debugging, but I can't do that due to broken screen.

I guess I'll have to buy an adapter.
