I have a Dell Precision 5520 laptop (basically an XPS 15). The volume, mute, and brightness "function" keys have always just worked on this laptop with no additional configuration required ... until now.
Something has changed in the last week or two, and the keys no longer have any effect (except that the brightness increase key now toggles the maximized state of terminal windows).
Anyone else seen this recently?
Assuming no, anyone have any hints on how to debug this? I'm not really sure how these function keys work (i.e. are they keypresses, ACPI events, something else?).
Any thoughts appreciated. Thanks!
I think something like this happened to my Thinpad also during last weeks, but after some time, it started to work again. Did you try to reboot?
