Adamscomputerrepair , super nice guide , really appreciate it.
Firefox is broken due to an update of Ubuntu Mate, mine ( Powerbook G4 12" ) ran pretty stable with Ubuntu Mate 16.04 LTS Beta 1.
Beta 2 was a disaster on my Nvidia Powerbook.
Radeon on the 15" Powerbook G4 meant no HW acceleration last time I tried even with tuning all boot options so I'm going
to format the partitions and make my OS X Leopard partition better.
I feel without HW acceleration , VLC, Mplayer in Ubuntu Mate are left behind by Coreplayer without trying.
A tuned TFF or Webkit is more stable or faster then Firefox in Linux.
Once the default Ubuntu Mate install resolves these issues, I might switch back.
Debian is nice , lightweight when you're not running heavy DE on it like indeed Openbox.
OpenBSD/FreeBSD in my opinion have the 2nd best touchpad support next to OS X but only OpenBSD has packages and Lumina. Compiling X or any DE on FreeBSD is so cumbersome and slow , I gave up.
