Accessibility

The BIOS offers two modes of operation, GUI and Simple Text.

The GUI can be navigated to some degree via the keyboard. Left and Right arrow keys to move the selection and Space to activate.

For full keyboard support switching to simple text would likely be better.

That can be accomplished by:

  • Selecting and activating Config on the left side under Setup
  • Right arrowing until the drop down to the right of Setup UI is selected
  • active the drop down and select Simple Text
  • F10 (save and exit)
Note: Blind users may want to request the help of a sighted person to change BIOS settings

Hardware

Bluetooth

Bluetooth doesn't appear to work with the stock Qualcomm Wi-Fi 6E QCNFA765 modem. The modem is an M.2 2230 form factor and not soldered (on the AMD variant of the X13 Gen 2), and can be replaced easily with an Intel AX210.NGW.

Video

Brightness control

As of kernel 5.9 use the native brightness controller, use the acpi_backlight=native kernel parameter.

Audio

PulseAudio seems to work fine without manual intervention, but the ALSA audio device chosen by default may not be correct. You may need to change the default device. 

/etc/asound.conf
defaults.pcm.card 2
defaults.ctl.card 2

You should remember to unmute the volume.

Firmware

fwupd does not support this device yet.

UEFI

It is recommended to run the latest UEFI version.

The "BIOS update" can be downloaded as an ISO image from the X13 support page and loaded to a USB stick.

Additionally, there is a UEFI option for customizing the Power profile that by default is tuned to Windows 10. See #Power Management.

Note: According to Lenovo engineer, the Windows 10 setting may be preferred if the kernel supports it.

Power Management

The UEFI provides two choices for the sleep mode in Config > Power > Sleep State. The Windows 10 mode (s2idle) is recommended, and results in about a 0.5%/hour drain while sleeping. Using the Linux mode (s3) may help if you are running an older kernel.

See Power management/Suspend and hibernate#Changing suspend method.

  2. The physical key has a symbol on it, which describes its function
  3. systemd-logind handles this by default

Gaming

This article or section needs language, wiki syntax or style improvements. See Help:Style for reference.

Reason: Written like a blog post, some irrelevant details (e.g. game launchers), needs to interlink with existing pages and avoid big config dumps. (Discuss in Talk:Lenovo ThinkPad X13 Gen 2 (AMD))

The APU incorporates a RENOIR from AMD GPU. It is possible to make a few optimizations to be able to run recent games that would otherwise have great difficulty.

To do this, you need a few tools and configurations:

-znver3 Linux kernel: Available via chaotic-aur or AUR, required for WineFSync support and other optimisations.

-ProtonUP: to install a customised version of Proton/DXVK with FSR support.

-Proton-GE: proton fork with native FSR support.

-Steam: to launch your games

-Heroic: to launch your games

-LACT: to manually specify the GPU frequency, which is necessary for certain games that don't push it to the limit, with a clear degradation in performance in this case.

If you only want a game machine, you can optimise the launch parameters via /etc/default/grub wich removing mitigations too (enable it if you prefer security by removing mitigations=off) : 

/etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="apparmor=0 security=apparmor lsm=landlock,lockdown,yama,integrity,apparmor,bpf udev. log_priority=3 clearcpuid=514 module_blacklist=pcspkr,snd_pcsp tsc=unstable mitigations=off iommu=pt amd_pstate=active amdgpu.abmlevel=0 idle=nomwait rcu_nocbs=0-$(($(nproc)-1)) processor.max_cstate=5’


Editing environment variables : 

/etc/environment
WINEFSYNC=1
#DX12 support
VKD3D_DEBUG=none
VKD3D_SHADER_COMPILE_OPTIONS=fast_math
VKD3D_FRAME_RATE=24 # choose 24 or 30fps max 
#Enable FSR for Proton-GE or Wine-GE, works only with DXVK
WINE_FULLSCREEN_FSR=1
WINE_FULLSCREEN_FSR_MODE=performance # choose performance, medium, quality
#Choose global config file for directx 9/10/11 support with DXVK. (Alternatively, you can comment this line and include this file next to the executable in each game)
DXVK_CONFIG_FILE=/home/youruser/.config/dxvk.conf
#Force using radeon vulkan support

vblank_mode=0
VK_LAYER_LUNARG_standard_validation=0
MESA_NO_ERROR=1
VK_LOADER_DISABLE_EXTENSIONS=VK_EXT_debug_marker,VK_KHR_surface

Edit /home/youruser/.config/dxvk.conf or your dxvk.conf next to the game executable : 

dxvk.conf
----------Various---------
dxgi.syncInterval = 0
d3d11.relaxedBarriers = True
d3d11.apitrace = False


Enable HUD---------
dxvk.hud = api,fps,memory,gpuload,version


Optimisation---------

d3d11.ignoreGraphicsBarriers = True


HDR---------
dxgi.enableHDR = False
dxgi.enableUe4Workarounds = False



Fix framerate 24 or 30---------
dxgi.maxFrameLatency = 2
d3d9.maxFrameLatency = 2

dxgi.maxFrameRate = 24
d3d9.maxFrameRate = 24

dxgi.numBackBuffers = 2
d3d9.numBackBuffers =2




Fast Vsync-----
dxvk.tearFree = False


Vsync-----
dxgi.syncInterval = -1
d3d9.presentInterval = -1



Disable Anisotropic Fltering---------

(0-16)-------
d3d11.samplerAnisotropy  = 0
dxgi.samplerAnisotropy  = 0
d3d9.samplerAnisotropy  = 0


Texture sharpening 

( -2-1)--------
d3d11.samplerLodBias = 0.1
dxgi.samplerLodBias = 0.1
d3d9.samplerLodBias = 0.1
d3d11.clampNegativeLodBias = True
d3d9.clampNegativeLodBias = True


Supersampling---------

(True-False)--------------
d3d11.forceSampleRateShading = False
d3d9.forceSampleRateShading = False


Optimisation--------------

d3d11.dcSingleUseMode = True
d3d11.maxFeatureLevel = 11_0
d3d11.maxTessFactor = 8
d3d11.relaxedBarriers = False


Vram max 2048 or 4096--------------
dxgi.maxDeviceMemory = 2048
dxgi.maxSharedMemory = 2048

Now if your on Gnome, on login screen, choose Wayland which offers a much smoother gaming experience when the frame rate drops.

Launch Proton-Up and choose lateste version of Proton-GE for Steam/Heroic, and config them to using this version.

In Gnome, don't forget to set power to performance in settings.

Launch LACT tool for AMD GPU, and choose in "OC" TAB to enable service, then reboot system.

Launch LACT again, and in OC Tab, choose Highest Clocks. This will increase the GPU's capacity to its maximum. Note that this is not overclocking.

Launch your game and enjoy. :-)


You can optimize config file for engines too.
