I’m using VIM3 Pro with Ubuntu bionic.
But I have found some difficulties while installing apps and drivers on this Ubuntu version. (Teamviewer, Anydesk, Printer drivers, …).
So,
1, When will the Ubuntu Mate is going support for Khadas VIM3 pro?
and Do you have plan to create images for Ubuntu Mate in the future?
2, If I use Khadas VIM3 pro as a computer, can I install Ubuntu Mate for ARM architecture on it?
You should be able to install the Mate desktop Environment on top of the existing XFCE, Assuming that all the dependencies are maintained by Ubuntu Distro ARM aarch64 team.
Hard to say, as it takes alot of work and time to make another DE image and this question would be for Ubuntu Arm team.
Depends on what applications are you looking for. Only if those application developers have an arm aarch64 source then any distro can package it but if the core developers don’t maintain aarch64 source then its very hard to get it to work.
