Im using 2019 samsung curved smart tv version UN55RU7300FXZA and a ubuntu version 18.04.4 LTS
.I've tried using the built inn chrome cast but the tv noticed on my laptop but it tells me source not supported.But I've noticed in the connections menu that it works with only windows 8 and 10 versions.And i don't wan to buy a device ,has anyone found an app on the samsung apps or any wireless way to connect.or some one who has their code on Github.
