PC keyboard unknown scancodes (Power, Sleep, Wake)

PC keyboard unknown scancodes (Power, Sleep, Wake)

[Marek Michalkiewicz]

Hi,

these three keys (on a cheap no-name "Designed for Win*" keyboard ;)
produce "unknown scancode" kernel messages when pressed or released.

Power - e0 5e
Sleep - e0 5f
Wake  - e0 63

I'd suggest adding support for them to linux/drivers/char/pc_keyb.c
but I'm not sure who maintains this file, so reporting this here...

Thanks,
Marek

You can use the setkeycodes command to tell the kernel about them.

Maybe you are using console-tools instead of kbd?
Check with strace that it does the KDSETKEYCODE ioctl.

It doesn't seem to fix the problem:

# dmesg -c
# setkeycodes e05f 127
# setkeycodes e05e 127
# dmesg -c
[ pressing some keys here ]
# dmesg -c
keyboard: unknown scancode e0 5e
keyboard: unknown scancode e0 5e
keyboard: unknown scancode e0 5f
keyboard: unknown scancode e0 5f

Am I doing something wrong ?
