Linux Key Remapping

1. Copy your generated file cleanly into the system overrides directory

sudo cp ./your-generated-file.hwdb /etc/udev/hwdb.d/99-keyboard-deconvolutor.hwdb

2. Compile the text overrides into the kernel’s binary system database

sudo systemd-hwdb update

3. Force the active udev daemon to reload its configuration state maps

sudo udevadm control --reload

4. Trigger the active hardware driver matrix to activate your layout live!

sudo udevadm trigger --sysname-match="event*"
