multi screen support in ozone wayland #468

Closed mbinoy closed 6 years ago

mbinoy commented 7 years ago

Hi

https://github.com/01org/ozone-wayland/blob/master/wayland/display.cc#L622 The above says the multi screen support is not added, is any one started supporting this? Or any plans on this implementation, kindly let us know.

Yes will that add support for changing scaling when moving between screens with different DPI? This works great when running Gnome on Wayland.

nickmessing commented 7 years ago

@jhagberg, you said it works great on gnome on wayland, is it a part of google-chrome-stable? It doesn't work for me.

jhagberg commented 7 years ago

Sorry if I am unclear. I mean that the Gnome apps like file browser and such works very good. It scales depending on what screen the app is moved to.

nickmessing commented 7 years ago

@jhagberg, oh, is there any web-browser based on Webkit/Blink that supports that atm or we are stuck with not working properly chrome and ff?

jhagberg commented 7 years ago

I have not seen anything yet. My workaround at the moment is running chrome on the laptop and chromium on the other screens. If you set the primary screen to the external monitor after you start chrome on the laptop it will have another scaling. I will investigate more

nickmessing commented 7 years ago

@jhagberg, I'm using fish shell and I use this as a workaround:

function chrome
    set -lx WAYLAND_DISPLAY wayland-1
    google-chrome-stable -high-dpi-support=1 -force-device-scale-factor=1
end

Basically if you run chrome from terminal it's on external screen, if it's just by "click" it's on main screen :)

jhagberg commented 7 years ago

aha. Can you have two versions of chrome running? I cant get this to work in bash when I already have a instance of Chrome on HDPI laptop display.

nickmessing commented 7 years ago

@jhagberg, Unfortunately no, I use stable and beta for that :)

I've been able to use Ozone-Wayland in a multi-screen setup on the GENIVI Platform. It features the Wayland IVI extensions, which let a controller application define regions in any available screens and assign surfaces to them. In this scenario, applications aren't aware of the actual screens and don't deal with them directly, that's why it works despite this open issue.

mbinoy commented 7 years ago

@jaragunde yes, same experienced in my side, but what missing currently is multi seat handling, getting the touch working at the same time for both the windows is not handled at the moment. probably this leads to adding multiple screen / seat supported in ozone wayland.

jaragunde commented 7 years ago

@mbinoy right, it's currently not possible to e.g. assign different seats to different browser windows. We are currently trying to address that scenario to include Chromium in the next release of GENIVI.
