hmm. i wouldn't expect the button to work in gnome, but i'd
expect the sugar bindings to continue working. the first check,
though, it to see if the olpc-rotate command works from terminal.
when olpc-kbdshim installs, it patches sugar to run that command
rather than do its normal internal calls to xrandr. so if the
command works, but the key doesn't, the debug path is pretty
short, at least, i think. (is is possible that sugar installed
after olpc-kbdshim? that would explain it.)

the grab keys are the two with the little hands, at either side
of the space bar. on an "industry standard" keyboard, they would
be the bear the "industry monopolist" logo. :-) when you hold
either down, a using the touchpad should cause whatever you're
looking at to scroll. (if it's capable, of course -- i.e., wide
or tall web pages, or terminal sessions with any amount of

i have several questions about how XO-specific hardware will be
supported going forward. i assume the sugar folks would rather
not continue carrying hardware specific key-bindings for rotation
and brightness for instance, but i don't know what their current
