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:

  • can you provide specifics about the keyboard? Commented Oct 2, 2017 at 0:06
  • Interesting. Is the key also present in the kernel input layer? Run evtest as root, select your keyboard, try autorepeating keys and pressing no keys at all. Commented Oct 2, 2017 at 4:38

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 command sudo modprobe -r peaq_wmi.)

It turns out that disabling PEAQ WMI hotkeys fixes it. I disabled PEAQ WMI hotkeys through first checking xinput list, to find the id:

[email protected]:~$ xinput list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Dell Dell KM632 Wireless Keyboard and Mouse id=11 [slave pointer (2)] ⎜ ↳ Dell Dell KM632 Wireless Keyboard and Mouse id=12 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=16 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Video Bus id=8 [slave keyboard (3)] ↳ Sleep Button id=9 [slave keyboard (3)] ↳ Dell Dell KM632 Wireless Keyboard and Mouse id=10 [slave keyboard (3)] ↳ Lenovo EasyCamera: Lenovo EasyC id=13 [slave keyboard (3)] ↳ Ideapad extra buttons id=14 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=15 [slave keyboard (3)] ↳ Dell Dell KM632 Wireless Keyboard and Mouse id=18 [slave keyboard (3)] ↳ PEAQ WMI hotkeys id=17 [slave keyboard (3)]

In this case, the id is 17. Then, in the .xinitrc, I added xinput --disable 17, or the id that is causing trouble, which fixes the problem.

  • which kernel are you running? I believe this came from a recent update in my end, I'm running 4.13.3-1-ARCH on a x86_64 Lenovo 80K9 Commented Oct 8, 2017 at 15:30

I have the same issue on elementaryOS after latest kernel update. I posted about it here. Using one of the answers, sudo modprobe -r peaq_wmi, solved the problem for me.

EDIT: Adding xinput --disable 17 into .xinitr did not solve the issue permanently for me, so I run the command above after every boot. I have Lenovo Yoga 500-14IHW on elementaryOS.

Also, this bug is not Arch linux related, so please mark it as such, so more people would find the solution for this issue.
