Is it possible to add a feature that permits split a screen into two virtual screens in the wayland layer (not the videos driver)? Thanks
If you really do mean the "Wayland layer", then yes, any compositor can implement that any time it wants, and there is nothing new required from Wayland or any other part of the graphics stack. That would be purely a change in how a compositor of your choosing manages the application windows and reports output information. No changes to anything outside the compositor are needed.
Oh, if by "Wayland layer" you meant libwayland, then no. libwayland does not implement anything, it's just an IPC library that does not understand the messages it relays.
