Package: xorg
Version: 1:7.3+17
Severity: important
All my applications are getting KeyPress and KeyRelease events for the
Alt key every 20 seconds or so, but I am not pressing any keys. This is not such
a big deal for Gnome applications since they don't do anything when only Alt is
pressed, but it makes working with KDE applications and OpenOffice.org almost
impossible, since they focus/open the "file" menu when you press and release
Alt.
I am sure that I am not accidentally generating keypresses myself. I
have tested with Xev to monitor the events, and at the same time I have ran
evtest,
showkey and catted the output of /dev/input/event[0-9]. They all say that nobody
is pressing any keys, but Xev still sees KeyPress and KeyRelease events going
to the
window in focus. Also, those events happen in the same microsecond and
it's not physically possible to press and release a key in the same
microsecond.
To make extra sure that it's not a hardware problem I have tested three
different keyboards: Two different Dell USB keyboards and a Logitech PS/2
keyboard. This problem occured with all keyboards.
I'm marking this as "important" since it makes KDE applications and all
of OpenOffice.org pretty much unusable.
Below is the output of both xev and evtest at the same time. I have
placed comments inside then, prefixed by a #. As you can see, xev sees
keypresses from
my Alt key, but evtest sees no such keypresses on my keyboard.
Output from evtest:
