I don't want Chrome on my Linux system but I almost installed it last night. Why? Because apparently half the internet says that that is what is necessary if you want to screen share or mirror your monitor to a smart TV on the same network because "the linux implementation of Miracast is fucked". Oh, don't worry, you can try Brave or Chromium too, except they don't work because while the TV shows up as an option you can cast to, you can't actually cast because the option is grayed out due to some "specific media sites" error. Don't worry, this option can be changed in the //flags and if that doesn't work then try changing this other flag, except that other flag doesn't exist on Brave and Chromium and it must be assumed it only exists on Chrome.
But wait, there's a utility called MKchromecast, it mimics the ability without needing to install chrome, but doesn't recognize the TV. Oh it has all of these dependencies that need to be downloaded. It still doesn't work. There's always Gnome Displays, which has the exact same pattern of missing a bunch dependencies that must be hunted down and then not seeing the TV. While searching for dependencies on my software manager I find Jubii, a nice little media caster with a tidy, intuitive UI that happily connects to my TV immediately and cheerfully shows me all of media libraries but as soon as I ask it to play a mirror of my screen it loads for 2 minutes and times out with an error.
Then I realized it was 4:30am and I had to go to bed.
