Block user local input while remote assist is active

x11vnc -grabkbd -grabptr can be used for that, in /usr/share/epoptes/client-functions:

get_assisted() {
    background x11vnc -noshm -24to32 -grabkbd -grabptr -connect_or_exit "$SERVER:$1"
}

But it won't be committed upstream now, because we want to refrain from adding new features to epoptes for a few months, and only handle bug fixes, in order to make Precise backports easier.

We don't want to always enable that.
We probably don't want to default to that either, as many teachers want to help the students, but allow the students to control the client while they do that.
So we probably need an option for it, maybe in an epoptes settings dialog.

I added an option in epoptes settings for this purpose named grabkbdptr, defaulting to False. Currently there is no graphical way to set it, but there will be in the future.

So, if you want to block user local input when assisting a user, you should go to .config/epoptes/settings and set grabkbdptr = True.
