Installation

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]. https://docs.kernel.org/wmi/devices/alienware-wmi.html

Fan control

Enable the dell_smm_hwmon module to enable fan control:

# modprobe dell_smm_hwmon

Locate the hwmon path:

$ grep -l dell_smm /sys/class/hwmon/hwmon*/name

The fans can now be controlled:

# echo [value] | tee /sys/class/hwmon/[hwmonX]/[pwmY]

Where [value] ranges from 0-255, pwm1 is the CPU fan, and pwm2 is the GPU fan.

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-controller^AUR

Internal microphone

This article or section is being considered for removal.

Reason: linux-lts is more recent than the stated minimal kernel version needed. (Discuss in Talk:Dell G15 5515)

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.
