ASUS TUF DASH F15 (2022)

The kernel parameter is required for the laptop to successfully boot if using the proprietary NVIDIA GPU driver (or the variant, see the note in NVIDIA#Installation). It is not required if using or .

Advanced power management (Laptop Power Profile selection, battery charge limit and Panel Overdrive) need the ASUS Linux stack installed and running.

Install asusctl^AUR then start/enable .

As of October 2022, there is no way to control the keyboard RGB from Linux yet. Brightness control for the RGB does work using the function keys.

A kernel patch which adds TUF laptop support to the kernel module is available, has been submitted and is expected to be mainlined in kernel 6.1.

Adventurous users can find the patch on asus-linux GitLab.

See Kernel#Compilation for instructions on compiling a custom kernel.

Since Kernel version 5.11 the battery charge polling issue has been fixed in the mainline kernel. Running the G14 kernel from Asus Linux is now no longer necessary.

Firmware will allow you to easily put Secure Boot into Setup/Custom mode so you can deploy your own keys with .

There is no need to reset the TPM state to put firmware into setup mode, and also, if you have a usb thumbdrive with your CA files, or they are placed inside your ESP, you can deploy these certificates directly from the firmware as well.

Also, right after deploying your CA information, this laptop firmware will delete any additional EFI external drive boot entry it might have configured(USB, CD, PXE).

It is very important you start out with no existing configuration files in place from any of the Optimus Laptop managers and/or nvidia-xconfig. optimus-manager^AUR provides all of its own configs and existing files can interfere with its operation.

Ensure there are no files relating to Optimus, Bumblebee, supergfxctl, NVIDIA or Intel in any of the following locations.

/etc/X11/xorg.conf.d/
/etc/modprobe.d/
/etc/udev/rules.d/

If they exist, you should also delete or rename from /etc/X11/

Do not include or any of the NVIDIA modules in your early start up filesystem. Doing so can affect the discrete GPUs ability to properly power down.

Edit and remove i915 and all NVIDIA modules from the modules section then regenerate the initramfs.

Adding additional kernel parameters manually is not necessary when using optimus-manager^AUR, it handles everything including blacklisting nouveau when running the discrete GPU and power management functions of the discrete GPU.

Install the optimus-manager^AUR package.

You should edit optimus-manager.conf at before you start/enable .

The laptop fully supports NVIDIA fine grained power management which allows the discrete GPU to fully power down when not in use meaning there really should be no need to ever switch from hybrid mode however from testing, forcibly removing the card from the bus and powering it down does offer a slight increase in battery time over hybrid mode. Ultimately the choice is yours, luckily both options are easily handled and can co exist happily.

If you want to use hybrid mode and allow the GPU to handle its own power state then change the following

If you plan to manually switch between modes as your need dictates and would like the extra battery time then first you need to install (or if using a custom kernel) then change the following

Finally, for either scenario you need to change the following

/etc/optimus-manager/optimus-manager.conf

...
[intel]
driver=modesetting
...

Now start/enable . Using mode allows the GPU to power itself down and mode will forcibly remove the card from the bus and power it down.

offers 3 modes, those are ,  and .

To switch between modes simply use

$ optimus-manager --switch MODE

NVIDIA drivers since version 437.17 have Prime GPU rendering offload support included.

See PRIME#Configure applications to render using GPU for details on how that works.

Setting a limit to the battery charge can be useful to preserve its longevity when the laptop is used as a static workstation for long period of times. Set your preferred limit (in percent, from 20 to 100) using:

# asusctl -c 60

60% is usually considered a stable charge state for lithium-based batteries.

The power profile controls three settings: CPU scaling (only on Intel CPUs), Boost mode and fans speed. By default, three profiles are provided: , and . Custom profiles can be defined.

is automatically bound to switch power profile. This will imitate the way the original ASUS service works on Windows. Notifications should be enabled in order to know which profile is selected each time the shortcut is pressed. A specific profile can be manually selected using:

# asusctl profile -P quiet

While not necessarily saving power, some user prefer to disable turbo boost for smoother power delivery and less heat. To temporarily disable boost, execute the following:

# echo 0 > /sys/devices/system/cpu/cpufreq/boost

Or use the power profiles from asusctl to handle this automatically, as explained in #Power profile.
