Hi, llandwerlin. Does it work for other external display, such as ozone-wayland?

[llandwerlin-old, 2014/09/16 12:28:58]

What do you mean by external display?
Are you using 2 different GPUs?

[spang, 2014/09/16 16:31:28]

No, it doesn't work with wayland. I'm hoping we can abstract it better soon,
however for now ozone-wayland should be able to keep working via an alternate
path (MediaOzonePlatform).
