Headless Wayland - Incompatible connector name

sergioperez commented 3 years ago

Hello!

After trying to execute sway and kwin_wayland in headless mode, I observe that they both expose a different connector name, being it named "HEADLESS" in sway, and "VIRTUAL" in kwin.

What do you think that would be the best procedure to support these virtual monitors?

$ export WLR_BACKENDS=headless                                                                                    
$ export WLR_LIBINPUT_NO_DEVICES=1                                     
$ export WAYLAND_DISPLAY=wayland-1

Sunshine progress on the starting process with this PR. Now it is crashing, but I suspect this might be related with the drivers I have on my AWS instance and not with Sunshine itself.

$ export WAYLAND_DISPLAY=wayland-0
$ sunshine
