@shano said in Why is Wayland compositor and Lomiri so far in terms of functionality compared to Compiz and Unity7 released some 20 years ago?:

Compiz was released in 2006 and is still maintained. Unity7 was released in 2010 and is still maintained. My question is why Wayland and Lomiri are so far away in terms of functionality, plugins etc. compared to tech made 20 years ago.

Are we building on top or reinventing the wheel?

From what I see, Lomiri is not reinventing Unity 8, it is Unity 8.
I downloaded the Lomiri source code and counted roughly 18000 commits between 2013 and 2017 (end of Ubuntu involvement) and 1400 commits between 2018 and 2025. The main reason is probably that Unity was a business project with serious resources behind it, while Lomiri (the new name for Unity 8 since 2020) is an open source project with a few part time volunteers. Also, it may be that there was so much work in Unity that there is not a lot of new development necessary, the bulk of new work being in other parts of the full (and huge) smart phone stack. I did not count but I think that a large part of these 1400 commits are just translations.

I don't know Compiz but I tracked the project in its last hideout on Gitlab and counted about 30 commits in last 5 years, 20 of them in 2020. It's maintained in the most limited sense, there is almost no development.
