Vision 3.0 is a 35GB download, making it slightly heavier than many alternative Linux distributions, despite being based on the classic Debian project.
Debian based, but 35GB 😬
Edit: just realised that this comment doesn’t actually answer your question.
According to Linuxlap.com Vision uses Gnome2, or did in 2011 one v1 release. Looked all over and couldn’t find anything more than that
As @[email protected] said in another comment:
Still feels a bit excessive to front load all of it instead of making it an optional download on initial setup.
