udevd error message on boot: Error calling EVIOCSKEYCODE on device node ... Invalid Argument #281

Closed lukeflo closed 3 months ago

lukeflo commented 3 months ago

I'm not totally sure if this is the correct repo to post this issue, but after searching seems to be the best fit.

System

I'm running Void Linux, Kernel 6.6.31_1, using runit instead of systemd for service management.

The installed udev package is eudev.

udevd --version gives 251.

Error message

On every boot I get the following error messages:

2024-05-19T20:59:19.61478 daemon.err: [    4.444792] udevd[848]: Error calling EVIOCSKEYCODE on device node '/dev/input/event16' (scan code 0x8, key code 190): Invalid argument

Everything works fine, but the messages disturb the login process/display manager

Debug

I tried debugging the error message with the following commands. The output is attached:

udevadm info -a /dev/input/event16:

    KERNEL=="event16"
    SUBSYSTEM=="input"

Afterwards I run a test:

Unfortunately, I'm not as familiar with udev to understand those messages fully. It seems to have something to do with my Lenovo extra buttons. But so far, everything works fine.

Nevertheless, the messages are annoying on boot, as mentioned above.

Can anybody explain what all this means concrete and how to solve the error or at least surpress the messages for that special event?

Could fix ist myself. Maybe also a solution for people with a similar problem.

solution

For some reasons udev tries to load some keyboard assignments from /lib/udev/hwdb.d/60-keyboard.hwdb which deal with the wlan switch of a Lenovo Idea Pad. Since I have no Idea Pad but some other Lenovo notebook, those keys can't be assigned which causes the error.

Thus I just copied the file /lib/udev/hwdb.d/60-keyboard.hwdb to /etc/udev/hwdb.d/60-keyboard.hwdb and uncommented the particular lines mentioned at the end of the udevadm test call above:

# IdeaPad
evdev:name:Ideapad extra buttons:dmi:bvn*:bvr*:bd*:svnLENOVO*:pn*:*
# KEYBOARD_KEY_0d=rfkill                                 # airplane mode switch (toggle all wireless devices)
# KEYBOARD_KEY_08=f20                                    # micmute
# KEYBOARD_KEY_42=f23
# KEYBOARD_KEY_43=f22

After that, just rebuilt the hwdb-database with sudo udevadm hwdb --update.

Now the warnings on boot are gone. I recognized no other drawbacks, which isn't surprising since the switch does not exist on my notebook.
