Graphics

The CPU provides Radeon Vega Mobile graphics, and there is a Radeon RX 560X GPU (Wikipedia:List_of_AMD_graphics_processing_units#Radeon_RX_500_Series) with 4Gb of dedicated memory. Follow the instructions in the AMDGPU article.

root #lspci -k -s 01:00.0

01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Baffin [Radeon RX 460/560D / Pro 450/455/460/555/555X/560/560X] (rev e5)
        Subsystem: ASUSTeK Computer Inc. Baffin [Radeon RX 460/560D / Pro 450/455/460/555/555X/560/560X]
        Kernel driver in use: amdgpu
        Kernel modules: amdgpu

Note that once the amdgpu driver is working, Xorg will use the Vega graphics by default. To use the faster RX 560 GPU, export the DRI_PRIME variable before executing your program.

user $DRI_PRIME=1 glxinfo | grep -i devi

    Device: Radeon RX 560 Series (POLARIS11, DRM 3.33.0, 5.3.1-gentoo, LLVM 8.0.1) (0x67ef)

NVME SSD

In order to boot any linux device, it may be necessary to use the following kernel parameter with the laptop's included NVME SSD.

nvme_core.default_ps_max_latency_us=5500

The above parameter may also help if the system shows signs of intermittant stalling during frequent writes to disc (e.g. ext4 journalling), after the original SSD has been upgraded.

Wireless

root #lspci -k -s 03:00.0

03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter
        Subsystem: AzureWave RTL8821CE 802.11ac PCIe Wireless Network Adapter
        Kernel driver in use: rtl8821ce
        Kernel modules: 8821ce

The rtl8821ce wifi is not supported by Linux Kernel. The simplest way to enable it is to add trolltoo overlay and install net-wireless/rtl8821ce-driver:

root #eselect repository enable trolltoo

root #emerge -av net-wireless/rtl8821ce-driver

Sound

The laptop features AMD/Realtek HD audio.

root #lspci -k -s 04:00.6

04:00.6 Audio device: Advanced Micro Devices, Inc. [AMD] Family 17h (Models 10h-1fh) HD Audio Controller
        Subsystem: ASUSTeK Computer Inc. Family 17h (Models 10h-1fh) HD Audio Controller
        Kernel driver in use: snd_hda_intel

Configure ALSA with the following driver settings:

KERNEL

Device Drivers --->
    <*> Sound card support
        <*> Advanced Linux Sound Architecture --->
            HD-Audio  --->
                -*- Allow dynamic codec reconfiguration
                [*] Support initialization patch loading for HD-audio
                <*> Build Realtek HD-audio codec support
                <*> Build HDMI/DisplayPort HD-audio codec support
                -*- Enable generic HD-audio codec parser
          (2048) Pre-allocated buffer size for HD-audio driver

Touchpad

The laptop's touchpad will probably be an Elan 1200 model, which may not be detected by system tools, including lspci.

To enable it, use the following kernel configuration settings:

KERNEL

Processor type and features  --->
    [*] AMD ACPI2Platform devices support
Device Drivers  --->
    -*- Pin controllers  --->
        <*> AMD GPIO pin control
    HID support  --->

            <*> HID over I2C transport layer
    I2C support  --->
        I2C Hardware Bus support  --->
            <*> AMD MP2 PCIe
            <*> Synopsys DesignWare Platform
            <*> Synopsys DesignWare PCI
    Input device support  --->
        Mice  --->
            <*> ELAN I2C Touchpad support
            [*] Enable I2C support
            [*] Enable SMbus support

Keyboard

This model does not come with RGB keyboard lighting, only red backlight. Kernel 5.3 and later support changing the keyboard backlight brightness through the standard hotkeys, without any extra configuration.
