There are some notification (so we know we got debugging output properly) but none of them are related to brightness keys. David DEMELIER wrote: >>> I added them and I got a big output in dmesg but still no message when >>> pressing fn-keys. > No message at all, like I didn't do anything Then no good news. I can't help you. Your BIOS doesn't create the notification required by ACPI specification section B.7 Your's acpidump show that the notification may be sent, but we know the prerequisites that's need to be fulfilled. It may be a initialisation of something or so. If you have older than lates version of system BIOS (e.g. F.12 revision) the upgrade may help: http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=3934829&prodTypeId=321957&prodSeriesId=3934828&swLang=13&taskId=135&swEnvOID=4056#120 May be someone smarter may help better to you. You should save output of: 1. acpidump -dt 2. devinfo -vr 3. dmesg after boot with ACPI debugging turned on somewhere then send URL to the PR so anyone can read it. I'm sorry I have no better response to you ...
