Display brightness

Make sure you are using Linux 5.13 as display brightness adjustment won't work on older kernels.

The easiest way to get it is to install Ubuntu 21.10 https://ubuntu.com/download/desktop

Sleep mode

  • Slowly blinking green light and no other response after wake up?
    The led flashes slow green when the laptop is powered on and the lid is closed.
  • Sleep mode drains battery very fast?
    This is because default mode is "s2idle" aka "freeze" (S0 ACPI Suspend-To-Idle state).

To fix both issues run the following commands as root:

echo open > /sys/module/button/parameters/lid_init_state
echo deep > /sys/power/mem_sleep

To make these changes permanent, modify your /etc/default/grub file to have the following line and run sudo update-grub after that:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash button.lid_init_state=open mem_sleep_default=deep"

"deep" sleep mode is the S3 ACPI Suspend-to-RAM state.

If you want the S4 ACPI Suspend-to-disk (Hibernation) state to work, you will need to set up a fixed key for your encrypted swap.

Suspend on lid close

Settings -> Power -> Automatic Suspend (When on battery power) -- must be set! Otherwise closing the lid won't suspend the laptop.

Webcam

Reload the uvcvideo kernel module with the "quirks=512" argument:

sudo modprobe -r uvcvideo
sudo modprobe uvcvideo quirks=512

Add the following to /etc/modprobe.d/razer.conf file to make this permanent:

options uvcvideo quirks=512

Nvidia GPU

sudo apt -y install nvidia-driver-470

By default you will have your dGPU "on-demand", you can query it:

sudo prime-select query

To use your dGPU, you need to run your app using the following arguments, running glmark2 in the following example:

 __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia glmark2

while glmark2 is running, you can use nvidia-smi command to confirm the app is indeed using dGPU.

Or, you can switch to dGPU only, sudo prime-select nvidia and reboot.

Powering off your dGPU

Switch to iGPU (Iris Xe Graphics) only, sudo prime-select intel and reboot.

You can try to entirely power off dGPU to save more battery power, https://github.com/mkottman/acpi_call.git

I haven't tried that yet, please report if it worked work you :-)
You can probably check if you still see your card using lspci.

Text scaling

Instead of using display scaling or fractional scaling, you can adjust text size directly:

gsettings set org.gnome.desktop.interface text-scaling-factor 1.3
