Kernel

Important
Kernel 6.7.5 does not boot, hanging between the ALSA device list and Freeing unused kernel image (initmem) memory steps.
Important
With kernels 6.10.4-6.10.8, connecting an external display freezes the system. 6.10.10+ is okay.
Important
With kernels 6.10.11-6.12.8, about 1/4 of the time, the system freezes upon boot. 6.12.11 seems to have corrected the issue.
Note
For AMD_MEM_ENCRYPT to become visible, set EFI_STUB=y.
Note
Setting KVM=y can cause issues with VirtualBox in 6.12+.[42][43]

initramfs

If using genkernel to make an initramfs, pass the option --no-ramdisk-modules. They are not needed for the system to boot successfully, and with the AMD binary blobs for the GPUs, the initramfs file will be over 200 MB otherwise. Pass other parameters as desired.

root #genkernel --install --kernel-config=/usr/src/linux/.config --no-ramdisk-modules initramfs

Configuration

AMD P-State

The AMD P-State driver should be used with this laptop.

Kernels 6.1.* and earlier

These kernels do not have the EPP modes built-in:

FILE /etc/default/grubGRUB config
GRUB_CMDLINE_LINUX_DEFAULT="amd-pstate=passive acpi_osi=Linux"

The parameter acpi_osi=Linux has no functional impact, but will change this boot message:

kernel: ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored

to this:

kernel: ACPI: [Firmware Bug]: BIOS _OSI(Linux) query honored via cmdline.

Refer to the power management guide's section on AMD P-State for more details.

Kernels 6.5.5 and later

The variable amd-pstate=passive can be removed from the GRUB config, as the value can now be set via CONFIG_X86_AMD_PSTATE_DEFAULT_MODE (shown in the kernel config above).[44]

asusctl

OpenRC

Currently only systemd is supported upstream.[45][46] For those interested in using asusctl with OpenRC, this documents some previous efforts.

BIOS

The latest BIOS[47] version as of June 2024 is 319 and can be safely upgraded to.

Important
It is generally recommended to watch forums for user reports prior to updating as previous updates have caused issues (notably, 313[48]).

Firmware updates

Use sys-apps/fwupd and refer to its page for more details. So far, only UEFI revocation database[49] updates have been available.

Hyprland

The configuration for the built-in laptop display is:

FILE ~/.config/hypr/hyprland.confMonitor
monitor=eDP-2,2560x1600@120,auto,1

/dev/dri/card0 is the 6700S/6800S and /dev/dri/card1 is the 680M. Because the iGPU is tied to the display controller, to make Hyprland run on the dGPU, one must write

Note
The previous WLR_DRM_DEVICES environmental variable has been replaced by AQ_DRM_DEVICES[50].
FILE ~/.config/hypr/hyprland.confTo use dGPU
env = AQ_DRM_DEVICES,/dev/dri/card0:/dev/dri/card1

to set the dGPU as primary and the iGPU as secondary. If the :/dev/dri/card1 part is omitted, Hyprland will not start because there is no display. For the same reason, trying to use env = DRI_PRIME,1 will also not work.

To use the 680M and extend battery life, one would reverse the above:

FILE ~/.config/hypr/hyprland.confTo use iGPU
env = AQ_DRM_DEVICES,/dev/dri/card1:/dev/dri/card0

Function keys and hot keys

Asus has programmed several of the Fn key combinations to perform unique tasks, as shown by the pictograms on the keys. For example, Fn + F6 is meant to open a screenshot utility. The Windows-only applications which would usually instantiate this functionality like MyASUS or Armoury Crate are entirely unnecessary for replication of similar behaviour on Linux, though the means of implementation will vary with one's desktop environment or window manager.

Depending on whether the current environment is X11 or Wayland, either xev[51] (available at x11-apps/xev) or wev[52] (available in GURU) can be used to reveal the keysym[53][54] input which occurs after pressing a physical key. Usually there is a clear 1-1 correspondence, but for this laptop, there are some non-obvious ones:

Physical key input Keysym input Keycode input Notes
Fn + Meta none none Meta is the Windows key, or SUPER in a Hyprland config. This key combo disables or enables the meta key. No keysym input occurs in either case.
Fn + F4 XF86Launch3 202 Intended to toggle the "Aura lighting effect"
Fn + F5 XF86Launch4 203 Meant for switching between fan modes
Fn + F6 Super_L + Shift_L + S 125 + 42 + 31 Super_L is the left CTRL key.
Fn + F9 Super_L + p 125 + 25 Meant for switching between "display modes" when external displays are connected.
Fn + F10 XF86TouchpadToggle 191 Enable or disable the touchpad
Fn + Super_L Return + Menu 127 This key combo is equivalent to right-clicking.
M4 XF86Launch1 148 Meant to open the Armoury Crate application.

The command showkey[55] can be used to get the keycodes. The user manual lists what Asus intended for these keys on page 43.

Keyboard brightness

Install app-misc/brightnessctl from GURU. Then add the following lines:

FILE ~/.config/hypr/hyprland.confKeyboard brightness keybinds
bind=, XF86KbdBrightnessUp, exec, brightnessctl --device='asus::kbd_backlight' set +1
bind=, XF86KbdBrightnessDown, exec, brightnessctl --device='asus::kbd_backlight' set 1-

Screenshots

Install gui-apps/grim. Then add the following line to use the Fn + F6 combination mentioned above:

FILE ~/.config/hypr/hyprland.confScreenshots with Asus F6 key
bind= Super_L Shift_L, S, exec, grim -g "$(slurp && sleep 0.5)"

KDE Wayland

Note
The variable WLR_DRM_DEVICES doesn't work to set the dGPU as primary under KDE.

KWIN_COMPOSE=O2ES[56] may be necessary to eliminate graphical glitches. Firefox doesn't work well with DRI_PRIME=1 in this case.

TLP

Here are TLP[57] settings that work well for performance on AC, maximizing battery life on battery, and limiting battery charge to 90% to extend battery life. 90% works fine despite the boot warning message about Asus laptops potentially not respecting it. These settings are based on a kernel with the P-State EPP driver (not the 6.1.* kernels) and TLP ≥ 1.6.0.

FILE /etc/tlp.conf

Troubleshooting

680M freezes

There is a known issue, perhaps related to DPMS, which may cause the system to freeze in a way that requires forcibly powering it off.[58] Investigation into a final solution is still ongoing. The link contains a long discussion of attempts to fix or reduce the occurrence of the issue for those interested.

Warning
A recent instance of this issue which seemed to occur simultaneously with attempting to put the laptop to sleep caused a root btrfs file system to become unrecoverable (bad tree block start, open_ctree failed, checksum verify failed, etc.[59][60][61]) Consider using ext4.

ccp_crypto: cannot load

If the message ccp_crypto: Cannot load: there are no available CCPs appears in the boot log, it is because Encryption and hashing offload support (CRYPTO_DEV_CCP_CRYPTO) was built into the kernel ([*]) rather than set as a module ([m]). Set it to module (shown in the kernel config section above), and the message should not appear after rebooting.

fTPM RNG stutters

See the "Encryption controller" row in the hardware table for references, and ensure that TPM HW Random Number Generator support is disabled as shown in the kernel configuration above.

Machine learning

Despite not being officially supported by ROCm[62], the 6700S/6800S can be used with PyTorch or Tensorflow. Set the environmental variable HSA_OVERRIDE_GFX_VERSION=10.3.0 to spoof the gfx1030 group of cards.[63] It can be prepended to terminal commands (e.g. HSA_OVERRIDE_GFX_VERSION=10.3.0 jupyter-notebook) or placed in a file like /etc/environment or a Hyprland config file:

FILE /etc/environment
HSA_OVERRIDE_GFX_VERSION=10.3.0
FILE ~/.config/hypr/hyprland.conf
env = HSA_OVERRIDE_GFX_VERSION,10.3.0

A list of currently available AMDGPU_TARGETS can be seen on the pages for packages like sci-libs/rocRAND. This variable can be set in package.use as follows:

FILE /etc/portage/package.use/package.use
*/* AMDGPU_TARGETS: -* gfx1030 gfx1031 gfx1032 gfx1033 gfx1034 gfx1035

Only gfx1030 and gfx1031 are currently in place. gfx1032 is the 6700S[64] and gfx1035 is the 680M.[65]

Mesa 23.1 crashes

Mesa (media-libs/mesa) 23.1.3 causes VA-API-related crashes when using the radeonsi driver on this laptop (e.g., when playing YouTube videos on Firefox).[66] 23.0.3-r1 and ≥ 23.1.5 do not have this issue.

rocminfo

Version 5.4.3 of dev-util/rocminfo works as expected. Newer 5.* versions gave this error:

user $rocminfo
ROCk module is NOT loaded, possibly no GPU devices

6.* versions work fine.

Suspend

It used to be that this laptop could be put to sleep and woken back up, but the fans would not spin after waking and a reboot was needed to get them back. This has happily been recently fixed[67][68][69] and is no longer an issue as of the 6.1.41 kernel. The following command can be used to suspend from the terminal:

root #systemctl suspend

Running it as a normal user will result in a reboot.

Notes

The "Header and Data" data under "Handle 0x0009, DMI type 44" was removed, along with serial numbers and OEM Strings.

Benchmarks

Some benchmarks of the 6700S dGPU are available here.

6900HS

Some generic 6900HS benchmarks are available.

This is with --jobs=14 and --load-average=9 in make.conf.

Note
All of the below data was collected under the environmental condition of WLR_DRM_DEVICES = /dev/dri/card0:/dev/dri/card1.

OpenCL

With HSA_OVERRIDE_GFX_VERSION=10.3.0 as an environmental variable, running clinfo will hang indefinitely if run as a normal user, but not when run as root. If it is set to 10.3.2 or 10.3.5, this is not an issue. The first clinfo output below was run with HSA_OVERRIDE_GFX_VERSION=10.3.0 as an environmental variable. The OpenCL hardware database has other reports on these devices as well.[70][71]
