I got Ubuntu Mate 20.04.2 installed and working on my GPD P2 Max. Mate is not the best desktop for a touchscreen, so I installed Ubuntu Desktop (IE: Gnome Session and Gnome 3). Then I discovered that the kernel cannot be upgraded without losing the touchscreen capability, when I tried to upgrade to 20.10. Now I am having to reinstall 20.04.2. Anyone know of a way to get a newer kernel working with the touchscreen?
I am also wondering why the developers of the GPD P2 Max (and the other related devices) decided to semi-officially support Ubuntu Mate and not Ubuntu itself? Gnome 3 really is a much better user interface for a small touchscreen device.
