## Installation

Add `acpi_backlight=native` as a kernel parameter to be able to adjust screen backlight.

As of Linux kernel 6.1, the backlight system was revamped, breaking compatibility with some Nvidia Optimus compatible laptops. If omitting the `acpi_backlight` doesn't work, try setting it to `nvidia_wmi_ec`[1].

## Keyboard backlight

Install dell-g15-controllerAUR 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.AMW3.WMAX 0 0x15 {1, 0xab, 0x00, 0x00}" > /proc/acpi/call
    # echo "\_SB.AMW3.WMAX 0 0x25 {1, 0x01, 0x00, 0x00}" > /proc/acpi/call

Turn off:

    # echo "\_SB.AMW3.WMAX 0 0x15 {1, 0xa0, 0x00, 0x00}" > /proc/acpi/call
    # echo "\_SB.AMW3.WMAX 0 0x25 {1, 0x00, 0x00, 0x00}" > /proc/acpi/call

For users of Dell G15 5520 (Intel version), you want to use these commands:

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-controllerAUR

## Internal microphone

The patch for the internal DMIC is upstream, and it works starting with kernel version 6.3.x.

## 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.
