Public bug reported:
The F5/F6 keys used to work to set the keyboard backillumination level
with 18.04 but they do not work anymore with 18.10 4.18.0-10-generic
The back illumination can be turned on with : echo 255 >
/sys/class/leds/smc\:\:kbd_backlight/brightness but not anymore with the
Fn key
Here we go (except if it would be reverted before 4.12 but why would it?)

I think you mean this patch? It will probably take quite some time to
find its way to the package. I'm going to try to compile a patched
ubuntu kernel in the meantime. thanks.

Ok! thanks at lot.
Apple has zero interest in fixing the legacy BIOS. Therefore I assume they will

Is the "n" mode (much faster) supposed to be supported by the broadcom

All the other issues (sound and touchpad) are solved in 3.12-rc3 except the
