Hi, 1st thanks for all the work of making Chultrabooks possible. Yesterday I installed the Coreboot bios and Linux Mint Mate. Pretty much everything works except Screen Brightness and Keyboard Backlighting via the function row keys.
Is there a way to add a screen brightness function?
Is there another keyboard shortcut I could use?
Fortunately the screen is bright enough where it is set, YT looks great, my sound and volume keys work fine. It’s just Brightness I need help with.
Thanks
Did you take a look at GitHub - WeirdTreeThing/cros-keyboard-map: Utility to generate keyd configurations for use on Chromebooks?
Awesome! I got keyboard backlighting back! I didn’t get adjustable screen brightness via the keys, but Linux Mint has a panel applet. Right click on the Panel, Add to Panel, and search “Brightness”.
I’ve got full functionality now!
This probably means that the keyd config didn’t correctly remap the keys or that Linux Mint is not handling the keys properly. What does evtest show when you press the key?
Hi, sorry I don’t quite know the syntax for evtest. I tried evtest --query /dev/input/eventX
for type I put EV_KEY, for value brightness or “F7” wasn’t recognized so I left it blank.
Nothing is returned when I press the brightness key. It’s not a big deal as I did find a screen brightness applet in LM MATE. so I can adjust brightness from the panel, just not with the keys. Alt + Brightness does work for the keyboard back light.
What happens when you run sudo evtest and then the number for “AT keyboard” (or something similar), and then press the brightness keys (you might have to stop keyd first)?
