Long time fan of Ubuntu MATE here! Also a bit of a GPD fan.
I am receiving a GPD MicroPC tomorrow, and I would love to get Ubuntu MATE running on it. I looked at the specific release for MicroPC, and I noticed it is for 20.04.4 LTS (Choose a release | Download)
Is that what I should use even though it is an older version? Is 22.04.1 release for general amd64 systems the better choice? (Choose a release | Download)
I used to have a GPD PocketPC and the hardware is.. unique. Is there something I can do to help get a 22.04.1 build made for GPD MicroPC? Can I donate some cash towards that work?
