Yes, there are some events that I don't even know how to trigger. Here an additional event that I get from time to time: [20052.604628] dell_wmi: Received WMI event (02 00 00 00 0e e0 0f 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00) [20052.604634] dell_wmi: Unknown key e00e pressed According to my acpi table, this has to do with battery related stuff. On a side note, I guess this event can be added to the "ignore list" of the legacy keymap. Anyway, I think that reading the acpi dump of my laptop is easier than collecting and reading these logs. However, things are implemented in a different way (probably this is the difference between "WMI Interface Version" 0 and 1), so I don't know how helpful it can be.
