Comment 14 for bug 524967

Dear bas,
I really don't know when an official fix will be available.

I think that the problem is related to the change in the way fn keys are dealt with: the new trend is to manage the events generated by the key pressure using gnome power management (or something like that, I don't remember exactly).
I have fixed the problem just adding the key pressure events in the "old" acpi management mode (acpid I think). Then I have binded the managed events with custom scripts that use the setpci utility to manipulate video brightness.

I have done it just for myself... then posted to give a quick fix to other having the same issue.

The problem is that fn keys generate custom events from one manifacturer to another and often from one model to another inside the same vendor!. So, it is almost impossible for developer to release software containing all the fn-keys events binding for all the laptop models of all the vendors.
Anyway, when the problem hits many people (i.e., the laptop is bought by many people using linux) then probably an official fix will be released.

So, I don't think that an official fix will be released very soon.

Cheers

Francesco
