I am using Manjaro now for more than three years and never had any problems. After this long time I recently completely reinstalled my computer. Since then I experienced a very weird bug about my keyboard: Sometimes, apperently randomly, certain (but always the same) keys do not work and I have to click them multiple times until the character is actually typed. The keys where I observed this to happen are the
left Ctrl key (and only the left, not the right!), the
Alt key and the
?. I wouldn't really bother about this but the randomly non-working left control key is extremely annoying. Also, and I noticed this only in the login screen, the 5 and 6 sometimes don't work for a few seconds.
Weirdly enough, the output of
xev -event keyboard
seems to respond to all keystrokes in all circumstances, so I am very certain that this is not a hardware problem.
Does someone have any idea what might be wrong?
