Hi Mario! Eric Light wrote me that on his Dell Latitude E6410 laptop, dell_wmi prints following messages into dmesg at every boot. [ 14.254258] dell_wmi: Unknown key with type 0x0011 and code 0xffd0 pressed [ 14.254259] dell_wmi: Unknown WMI event type 0x12 [ 14.487922] dell_wmi: Unknown key with type 0x0011 and code 0xffd1 pressed [ 15.014983] dell_wmi: Unknown key with type 0x0011 and code 0x01e3 pressed Seems that in dell_wmi we are completely missing processing of WMI events which starts with 0x0012 and then there are some unknown codes 0xffd0 and 0xffd1. Do you have access to documentation what are those code at all? And what is hidden behind WMI events which starts with 0x0012? Also Eric wrote me that pressing brightness up or down key generates following events: Brightness Up: [ 1103.717988] dell_wmi: Unknown key with type 0x0011 and code 0xffae pressed [ 1103.717990] dell_wmi: Unknown key with type 0x0011 and code 0xff81 pressed Brightness Down: [ 1157.078641] dell_wmi: Unknown key with type 0x0011 and code 0xffac pressed [ 1157.078644] dell_wmi: Unknown key with type 0x0011 and code 0xff80 pressed For me it looks suspicious because why pressing one key generates those two 0x0011 events and why next one is generated after 2-3s... I think the best way is to define all those events in dell_wmi to be ignored (as I have not heard that brightness does not work), but it would be a good idea to know we are going to ignore. -- Pali Rohár pali.rohar@xxxxxxxxx
