Hi Pali and Mario, So sorry for the slow reply. Today I updated my BIOS from A01 to A17. Still early in the boot process I see: [ 16.631141] dell_wmi: Unknown key with type 0x0011 and code 0xffd0 pressed [ 16.631143] dell_wmi: Unknown WMI event type 0x12 When I hold the Fn key and press the screen-brightness-toggle key, and the keyboard backlight toggle key, the dmesg logs still receive: [11642.428479] dell_wmi: Unknown key with type 0x0011 and code 0x0188 pressed [11644.535419] dell_wmi: Unknown key with type 0x0011 and code 0x0187 pressed [11646.819788] dell_wmi: Unknown key with type 0x0011 and code 0x01e2 pressed [11651.191689] dell_wmi: Unknown key with type 0x0011 and code 0x01e3 pressed # uname -a Linux eric-laptop 4.18.0-2-amd64 #1 SMP Debian 4.18.10-2 (2018-10-07) x86_64 GNU/Linux Hope this helps, and sorry again for the six month silence :-/ E -------------------------------------------- Q: Why is this email five sentences or less?
