I installed Ubuntu 20.04 two days ago because my old system wasn't supported anymore. I've tried very hard to work with Gnome Shell but there are several essential things that I can't get over. How is it possible that in 2020 a DE doesn't work well on more than 1 monitor? I mean, it works, but not how it should. I won't say anything about the top bar only showing on the primary monitor but if I'm focusing on another monitor and I hit the meta button to see the menu to search for an app or a file I have to check the main monitor. I could partially fix this with an extension but it's not updated and it won't work with the current Gnome version. So I had to install Unity, which is unsupported and has some bugs but at least doesn't stop me from doing basic things and doesn't get on my way. As a linux user is frustrating. I don't understand it. I can't see myself using anything else besides Unity for the foreseable future.
