[ibm-acpi-devel] thinkpad_acpi: unhandled HKEY event 0x60b1

[Gijs H. <gi...@hi...>]

Hello

I have a lot of these in syslog, along with the request to post that to
this mailing-list

thinkpad_acpi: unknown possible thermal alarm or keyboard event received
kernel: [23361.888606] thinkpad_acpi: unhandled HKEY event 0x60b1

This does not seem to be related to keys on the keyboard. I see the
messages appear when looking at the log, without touching the laptop.

This is on a brand new Thinkpad X1 5th Generation, running Debian Sid

'Everything' seems to work fine, except the Fn F5 and F6 keys (monitor brightness)

Xev shows:

KeyRelease event, serial 40, synthetic NO, window 0x1600001,
    root 0xe6, subw 0x0, time 8963607, (47,193), root:(1011,213),
    state 0x0, keycode 233 (keysym 0x1008ff02, XF86MonBrightnessUp), same_screen YES,3
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyPress event, serial 40, synthetic NO, window 0x1600001,
    root 0xe6, subw 0x0, time 8964030, (47,193), root:(1011,213),
    state 0x0, keycode 232 (keysym 0x1008ff03, XF86MonBrightnessDown), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

I already tried - to no avail - adding  these three, sequentially, to

GRUB_CMDLINE_LINUX_DEFAULT=
in
/etc/default/grub

1) "quiet acpi_osi=\"!Windows 2012\"" 
2) "quiet acpi_backlight=vendor"
3) "quiet acpi_osi=linux thinkpad-acpi.brightness_enable=1"


Yesterday, I sent an acpidump to Henrique (offlist).
