I hope I'm not stepping on toes to post directly to this mailing list, the hp-wmi author suggested I email about this issue here. The issue is that on my new laptop when I press the brightness hot keys I get the following ACPI errors (and nothing else happens): [ 3324.617378] ACPI Error: [^^^PEG0.PEGP.DD02] Namespace lookup failure, AE_NOT_FOUND (20130725/psargs-359) [ 3324.617386] ACPI Error: Method parse/execution failed [\_SB_.PCI0.LPCB.EC0_._Q1D] (Node ffff8801592fc730), AE_NOT_FOUND (20130725/psparse-536) [ 3325.604163] ACPI Error: [^^^PEG0.PEGP.DD02] Namespace lookup failure, AE_NOT_FOUND (20130725/psargs-359) [ 3325.604171] ACPI Error: Method parse/execution failed [\_SB_.PCI0.LPCB.EC0_._Q1C] (Node ffff8801592fc708), AE_NOT_FOUND (20130725/psparse-536) I'd love to get these keys working if possible. I am on the a 3.12.5 kernel with the latest version of my bios installed. These keys do work properly in windows. Thanks!
