On my laptop, turning on autorepeat (xset r on
) does not work. When checking the output of xev
, it seems that the reason why autorepeat fails is because another key is being pressed intermittently (although I am not pressing anything), which cancels autorepeating the currently held down key. When no keys are being pressed, the following events are recorded repeating consistently:
KeyPress event, serial 33, synthetic NO, window 0x1200001,
root 0x123, subw 0x0, time 1652400, (-509,794), root:(455,814),
state 0x0, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
KeyRelease event, serial 33, synthetic NO, window 0x1200001,
root 0x123, subw 0x0, time 1652400, (-509,794), root:(455,814),
state 0x0, keycode 221 (keysym 0x0, NoSymbol), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
It seems that a key with keycode 221 is being pressed, even when it is not.
Thus, is it possible to completely disable a keycode such that xorg does not recieve the keypress signal from that keycode at all? Or, is it possible to make keys autorepeat when held down, regardless of whether another key is pressed?
Update:
After running sudo evtest
, it appears that when the hidden output is coming from
/dev/input/event11 PEAQ WMI hotkeys
No other input device seems to send events when nothing is pressed.
Autorepeat works when checking keyboard events in evtest.
The full output of xev
running for a couple seconds when nothing is pressed:

It seems this is a bug introduced with kernel 4.13, as per Redhat bugzilla bug #1497861.
I found out that unloading the
peaq_wmi
module also serves as a workaround; it seems that someone already submitted a patch to fix the issue though.(To unload the
peaq_wmi
module one can issue the commandsudo modprobe -r peaq_wmi
.)
