Emit HID event when keyboard brightness changed via fn+space #53

Open Jules-Bertholet opened 2 weeks ago

Jules-Bertholet commented 2 weeks ago

Currently, changing the keyboard backlight brightness via fn+space does not notify the OS in any way. Therefore, OS indicators like GNOME Shell's keyboard backlight slider will show the wrong values. This PR corrects this issue by emitting a "Keyboard Backlight Set Level" HID event on fn+space. (The backlight brightness is still changed directly in firmware, so functionality in e.g. firmware menu won’t be affected.)

Could you explain how this event gets interpreted by Gnome? The kernel doesn't seem to know to handle it.

Unfortunately, proper testing reveals that Linux does not currently handle this HID usage, so I am marking as draft.

This would be really awesome, I think I tried that a few months ago and neither Windows nor Linux supported it :(
