Has anyone gotten a compose desktop application running on a chromebook? Would it be the same as running it on a linux machine?

Yes, in theory it should work as any other linux app, though it’s not the most user friendly way to run apps

using the Linux container, yeah it works pretty much like any other Linux machine. not supported on all Chrome OS devices though, and not all users will be able to use it (e.g. enterprise or secondary users might not be able to)
