Hi!
After many years of tinkering with Linux (from 1997...) and some 12 years of using it on a daily basis, I came to the conclusion that:
1. Either you are a top-notch programmer (That is: ASM, C++, Ojective C, Python) and very familiar to the GCC tools and distro development, IT IS BEST TO AVOID FIDDLING WITH THE DE;
2. OR: If there is any compatible DE that has been tested by the community and proved to work without major issues, just install that one, if you really desire that. Still, I have never came across such a DE on this forum...
3. After some 5 years of distro-hopping and accepting the narratives regarding DE compatibilities across many distros (Deepin claims this!) and trying this, practice says that what a distro says about its DE has nothing to do with installing it on a different distro, regardless the automation provided. It's just marketing hype.
And a final consideration:
While I made my choice some 5 years ago and as you can see it's Linux Lite, I can tell from experience that if you really want to use different DEs, you should move to Manjaro Linux.
Why that, it's a too long story which I'll make very short:
A. Arch (Manjaro is an Arch, an user-friendly one) has I guess at this time, the best available Linux Encyclopedia. I's likely that if you can't find your problem in Arch Wiki, you'll be searching a long time to find anything, if any result might come out at all.
B. Manjaro, by default, allows you to install some "Alien" DEs, and as far as I remember, Deepin is one of them. But here is a different story running behind the scenes: The included DEs, are crafted specially for Manjaro by their development team so, if they support that approach, it is likely that all included DE kits will work, regardless their origin. It is not the case for Linux Lite though...
C. A final thought... It all boils down to two choices: 1. If you are a workflow-centered person, you'll definitely apreciate Linux Lite, for it is IMHO the ideal distro for that specific purpose: low foot print, high resources availability for the Apps. While almost any Linux distro claims that, reality might often prove different if you know your stuff. 2. If you are an experiment-driven person, then I guess Linux Lite is a lesser recommended choice.
This distro is aimed towards a high efficiency, high stability and highest possibly compatibility with old architectures. And, belive me, it walks its talk!
