Is it possible to display all events that are generated in Xorg? Such as keyboard pressed, mouse events...?
A pretty quick search would likely yield
xev as a result. It will not show you everything that is pressed or typed in X ever. But rather, will allow you to see information about keycodes and mouse movements.
However, with the
-root option, you might be able to get
xev to monitor the whole X session. Note, if you do this, you'll make it pretty difficult to actually interact with any program since
xev will be capturing all input.
xev -root comes with an implied "YMMV". Another possible solution is to use
xinput to get the job done (though you need a recent version (1.6.1 or above)):
$ xinput test-xi2 --root
While the above should be able to capture all events, if your
xinput doesn't support
--root, you can use
xinput test on a particular keyboard or mouse device.

xevshould show you all events... it's just that it only monitors one window at a time. Perhaps one could hack a script to launch multiple copies of
xeveach monitoring one window so that you end up monitoring all of them?– CeladaJul 24, 2014 at 8:02
xev and xinput test don't show you touch events while xinput test-xi2 does.– u149796May 7, 2015 at 9:01

10"However, with the -root option, you might be able to get xev to monitor the whole X session." <= This is wrong. This way,
xevwill only capture events on the "root window", i.e. normally your desktop background.
xinputis the correct solution for capturing all events regardless of the currently active window.– FritzNov 17, 2015 at 13:07
