Hokay. progress.
Double fingers - middle click.
xmodmap -e "pointer = 1 3 2" to remap right to middle and vice versa.
Xephyr = Run native.
Window manager = Blackbox (Native)
Games = gtkboard selection and the DOS ones from before... All Run native.
I guess you could call that a fair result.
will look to repackage it all back up but the actual REQUIRED support is fairly tiny.
I am also 90% sure I can convince the games to run with the same wangle on FAT that we used on blackbox (simple redirecting crafted shell scripts) to save the need for stupid multiple copies for the games.
TODO: make OSK sit on right level. push events to active app and
not grab focus. (ie actually work)
build/port/use different window manager (blackbox is not very "click" friendly )
fix horrific menus in games (err somehow)
but yeah. result. no debian required.
