I've mint 19 xfce installed, and was originally using the 4.15 default kernel.
The function keys all worked out of the box, except for brightness. (I've been watching https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1775065 which I think is related.)
So I eventually installed xbacklight, and wired up brightness function keys (Func-F8 and Func-F9) to call `xbacklight -dec 10` and `xbacklight -inc 10` respectively. Good enough.
Then a week ago I upgraded to the 4.18.0-14 kernel (to see if it would fix some other issue). This stopped those keys working. When I go to add them again I find they are not being recognized at all. I.e. the other function keys still work fine, but it is like those two keys no longer exist.
It is a minor irritation (I mapped Alt-F8/F9 to adjust the brightness instead.)
But it got me wondering what kernel other people are using, and if they can confirm what works and what doesn't?
