lembas: I found /etc/X11/xorg.conf and inserted the section (assuming
"whatever" means whatever I put the was inconsequential). xev still did not
notice buttonpresses from my controller. I double-checked with evtest and
it's still sending input.
I guess with this I'm trying to get my X server to notice input from my
controller (much like it grabs input from mouse and keyboard). That would be
great, because "polling" with watch/evtest seems terribly inefficient to me,
and I could throw the XBMC start script into my xbindkeysrc file.
I know nothing about configuring Xorg. If I did maybe I could poke around and
get this idea to work.
