Create virtual screen to use as second screen

[vidister]

Is there a way to automatically create a virtual screen as vnc source?
The background is that I want to use my iPad as a second screen for my computer.

This is currently not possible, but might be in the future when virtual displays are added to wlroots.

The feature for virtual displays has just been merged into Sway. It involves creating a new display and specifying it's backend as headless and will be included in the 1.5 release.

See here: swaywm/sway#5216. There currently isn't any documentation (that I could find) but you might be able to derive the options by reading the relevant code here:https://github.com/swaywm/sway/blob/master/sway/commands/create_output.c

It works with sway \o/ ...

swaymsg create_output
swaymsg output "HEADLESS-1" resolution 3840x2160
wayvnc -o HEADLESS-1 0.0.0.0

(Importent change the resolution before starting wayvnc ... there are some errors ....)
(alternative for line 2, you could put something equal into .config/sway/config or use kanshi, wdisplays)

It is really slow + sometime it closed the connection without reason, and sometimes it crashed.
(is there a option to get logs in wayvnc?)

There's not a lot of logging, but there is some debug logging available if you run meson with --buildtype=debug. A debugger backtrace would help to know why it crashes, in which case it would be better to open a new issue.

It could be "slow" for multiple reasons: network connection, poor client, slow computer or poorly chosen encoding method.

@vidister I found this because I'm trying to use wayvnc to extend a screen to my Ipad, did this ever work for you?

@ldelossa #7 (comment) a few comments above (swaymsg commands to create display and use it with wayvnc) should be what you're trying to do, what's wrong with it?

More looking for, what app and how did you connect via IPad. Maybe some docs related to getting it to work with a new IPAD.
