I have a Lenovo X1 Carbon 7th Gen, where the brightness control keys are on the top row. Being a DELL veteran, I wanted to see if I could use Fn+↑ to raise and Fn+↓ to lower brightness.
Using evtest, Those combinations show up (understandably) only once as KEY_WAKEUP and KEY_SLEEP and they seem to be mapped in /usr/share/X11/xkb/keycodes/evdev
...
<I150> = 150; // #define KEY_SLEEP 142
<I151> = 151; // #define KEY_WAKEUP 143
...
I have no need of a sleep or a wakeup key. How could I re-use these keys to XF86MonBrightnessUp and XF86MonBrightnessDown?
