detect keypress

Daniel seems to have issues to detect whether a key is pressed on
linux outside of an event loop:

Basically he writes a code block that should do what he wants but:

"Mais ça, qui semble être la seule manière de faire, NE MARCHE PAS
parce que X bloque l'accès non-root à /dev/tty ou /dev/console"

translates to

"This, which seems to be the only way to achieve my goals, doesn't
work because X block non-root access to /dev/tty or /dev/console."

Anyone has an idea on how to solve this?
