Darter Pro 10 Mic Mute
As an update to the Fn-Mic (Mute/Unmute Microphone) not working. I contacted the System76 support and Aaron Honeycutt pointed me in the right direction. It requires a systemd change to get working somewhat outlined in this Github issue.
Create the following file:
nano /etc/udev/hwdb.d/61-keyboard-local.hwdb
Next, add the following:
###########################################################
# System76
#
# Fix for Darter Pro 10 Mic Mute
###########################################################
evdev:atkbd:dmi:bvn*:bvr*:bd*:svnSystem76*:pn*:*
KEYBOARD_KEY_81=micmute # Mic mute
I had to restart for the change to work.
I will have to figure out how I will handle future firmware updates. There are instructions here. Anyway, after a week I am super happy with the Darter Pro 10. Gentoo is working great on the system using the in-tree System76 module.
