Deepin has been said to be the most beautiful desktop environment, and Ubuntu is working toward making it part of the official flavor.
For those who like to customize, I ran across this... Ubuntu Deepin Desktop Environment (UbuntuDDE):
sudo add-apt-repository ppa:ubuntudde-dev/stable
sudo apt install ubuntudde-dde
Once it's installed, apparently you have to log out or reboot, then choose the session manager (choose lightdm for Deepin).
I haven't tried it, as I like my desktop just as plain and utilitarian as can be, but it might open new avenues of customization for those who are into that sort of thing.
Just went ahead to give it a quick try but I got this error message after running the install:
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)
But after logging out and back in, it worked. Not bad, although it's not very appealing to me personally. For some reason, the default font color is red?
I did run into another issue when I logged out, where I was left with just a black TTY but it wouldn't react to any commands, so I had to force it to shutdown. Maybe it's because it's a virtual machine? In any case, I took a snapshot first and I rolled it back to default Zorin Core.
Plus it is Chinese software, not that I am paranoid!
