THe support is good on the XPS. Everything works out of the box (apart from the standard linux trackpad multi touch issues.)

a word of caution, the 2019 13" has a stupid[1] keyboard layout. They cram the pageup/down keys above the left right keys. This caused huge amounts of issues for me, making it unusable. If this were to be fixed, it would be a very compelling machine.
