Audio

The inbuilt audio used for the speakers and headset jack needs sof-firmware to be installed.

For headset microphones, set the volume for PGA2.0 2 Master under the sof-hda-dsp sound card to at least 32 in alsamixer and mute Capture 1. The mic mute LED will only follow the status of the internal mic.

Keyboard backlight

Install dell-g15-controller^AUR for keyboard backlight control. Only static colors and morph effect is supported, and more complicated effects such as rainbow and breathing do not work yet.

Game Shift Mode

First install acpi_call (or acpi_call-lts for LTS kernel, acpi_call-dkms for other kernels) and load the kernel module:

# modprobe acpi_call

Turn on:

# echo "\_SB.AMWW.WMAX 0 0x15 {1, 0xab, 0x00, 0x00}" > /proc/acpi/call
# echo "\_SB.AMWW.WMAX 0 0x25 {1, 0x01, 0x00, 0x00}" > /proc/acpi/call

Turn off:

# echo "\_SB.AMWW.WMAX 0 0x15 {1, 0xa0, 0x00, 0x00}" > /proc/acpi/call
# echo "\_SB.AMWW.WMAX 0 0x25 {1, 0x00, 0x00, 0x00}" > /proc/acpi/call

Alternatively, the power mode and fan speed boost can be set using dell-g15-controller^AUR

Accessibility

The appearance of the BIOS is pretty simple and not very colorful, so it might work well with OCR software. The use of a mouse is not required.
