[Bug 1762385] Re: dell_wmi: Unknown key codes

Tue Dec 18 16:28:55 UTC 2018

I still get this error in Cosmic on a Dell M6500.

The M6500 does not have a keyboard RFKILL shortcut - in only has a
physical switch. That switch correctly enables/disables WiFi.

Is this the same bug?

Dec 18 09:04:28 localhost kernel: [ 2706.037523] dell_wmi: Unknown key with type 0x0011 and code 0xffd0 pressed
Dec 18 09:04:28 localhost kernel: [ 2706.037526] dell_wmi: Unknown key with type 0x0011 and code 0xffd1 pressed
Dec 18 09:04:28 localhost kernel: [ 2706.037527] dell_wmi: Unknown key with type 0x0011 and code 0xffd0 pressed

Note that I never use the Fn-keys, so I have no idea which key(s) it
would be complaining about.

Here is the output from using the physical switch:

Bug description:
  [Impact]

   * Bogus keycode messages produced by the kernel / user annoyance
   * rfkill keyboard shortcuts not working as intended on some Dell machines

  [Test Case]

   * check that there are no spurious kernel messages about unknown keys
  in journalctl upon RFKill key presses

   * check that RFKill key presses work correctly and kill/restore RF
  capabilities

  [Regression Potential]

   * The change is scoped to particular SKUs and thus should only affect them
   * It is related to matching gsd support, which is in-place on xenial and up

  [Solution]
  Cherrypick upstream commit https://github.com/systemd/systemd/commit/cab01e9ecf1c69656785e64f5fc94cd4ed09e57f

  [Original Bug report]

  RFKill key produces these messages in kernel log:

  dell_wmi: Unknown key with type 0x0010 and code 0xe008 pressed

  This key code is a notification and should be added as KEY_IGNORE
