Hapless research: Fedora 29 Mate edition and FreeBSD 12 with Mate desktop. Checking out Fedora package management and native OpenZFS with FreeBSD.
Fedora 29 Mate somehow 'remembers' this ancient dual monitor configuration when I unplug/replug the external vga monitor which for me is surprising as hell.
Pop!_OS would be fun to try out, I have troubles with Debian/Ubuntu Gnome3 on this lappy (Fedora 29 Gnome3 seems ok) though.
Nothing too GPU/CPU intensive obviously. Some 8bit with Fedora, vim, PDFs, podcasts, Joplin note taking/syncing, etc.
