Steam Deck (Magyar)

Note
This article discusses use of the Steam Deck with plain Arch Linux, not SteamOS. While the latter is an Arch-based distribution, it has
several packages
that differ from the
official repositories
, and is
not supported
by the Arch Linux community.

The
Steam Deck
is a gaming-focused handheld PC from Valve. Since it is completely unlocked and by design has full Linux driver compatibility, it can easily be used as an all-purpose handheld PC with
Arch Linux
.
Accessibility
The firmware has
white text on black background
, which should be fine with OCR. Blind users may still want to request the help of a sighted person to change firmware settings or
selecting a boot device
.
Navigation can be done with a keyboard and mouse, or the physical buttons (
DPad
and
A
,
B
,
X
,
Y
) and tactile screen of the device.
There is a single LED at the top of the device, but it does not provide diagnostic codes.
Telepítés
You can
install Arch Linux from the SteamOS "Desktop Mode"
, although this way of installing is more involved than using a
USB flash installation medium
through the microSD card slot or the USB-C port.
If you choose to use an Arch Linux installation medium, hold down
Volume Down
and press the
Power
buttons to boot on it when starting up the deck.
Firmware
Updating the firmware works with
fwupd
.
For the LCD models, firmware F7A0
131
is the first to enable support for the
amd_pstate
CPU frequency scaling
driver.
Shortcuts
Hold down
Volume Up
and press the
Power
button to access the UEFI settings,
Hold down
Volume Down
and press the
Power
button to access the UEFI boot menu (called "Boot Manager" in Valve's documentation),
Hold down
⋯
("Three Dots" button under the right touchpad) and press the
Power
button to access Valve's boot loader menu,
Hold down
Volume Down+Power+⋯
("Three Dots" button under the right touchpad) to reset the UEFI settings to their defaults (keep the two buttons other than
Power
held after the first blink of the LED: the LED will blink during the operation and stop once done, then release the buttons).
Audio
This article or section needs expansion.
Reason:
Test OLED model audio with mainline kernels, which should work since 6.10. (Discuss in
Talk:Steam Deck (Magyar)
)
The LCD model's built-in audio works out of the box since kernel version 6.1.
The OLED model's built-in audio requires compatible firmware, kernel and ALSA UCM rules in order to work:
The following firmware files need to be present in the system. They can be compiled from upstream source, or copied from the
steamdeck-dsp
package published in Valve's
jupiter
repository.
/usr/lib/firmware/amd/sof/sof-vangogh-data.bin
/usr/lib/firmware/amd/sof/sof-vangogh-code.bin
/usr/lib/firmware/amd/sof-tplg/sof-vangogh-nau8821-max.tplg
Neptune
kernel (from the
jupiter
repository) version 6.1.52 or newer works.
alsa-ucm-conf
1.2.11 or newer needs to be installed. Then, rules for
sof-nau8821-max
need to be added, such as by copying
/usr/share/alsa/ucm2/conf.d/sof-nau8821-max/
from
steamdeck-dsp
.
You may want to use the Bazzite kernel instead for audio support on the OLED model.
https://github.com/hhd-dev/kernel-bazzite
For troubleshooting, see
ALSA
and
PipeWire
. If ALSA can't access the built-in audio, check the kernel and audio firmware (see
ALSA#Firmware
and
ALSA#Driver configuration
). If ALSA works but PipeWire doesn't, check the UCM rules.
PipeWire
Some applications, notably
Wine
, cause audio crackling on the OLED Deck's built-in speakers. When using
pipewire-pulse
, this can be fixed by increasing the minimum quantum size in
pipewire.conf
:
default.clock.min-quantum = 256
256 is the lowest value that has been observed to work well with wine. Higher, safer values of 512 or 1024 can also be used.
Bluetooth
This article or section needs expansion.
Reason:
The bug was introduced by commits around March 2024, but have been backported to all LTS kernels. A seemingly related
fix for a Dell XPS 13 9310
might be applicable here, instead of the linked revert. (Discuss in
Talk:Steam Deck (Magyar)
)
A small Bluetooth quirk can be encountered on OLED models: a
kernel bug
prevents suspending if Bluetooth was turned off since boot. This means turning Bluetooth off requires a reboot.
Controller
The built-in game controller works out of the box, but is in
lizard mode
by default. In this mode, the touchpads act as a mouse, and
some buttons
as keys, while other buttons do nothing. One of the following methods can be used to remap the controller for gaming.
Raw
On some kernel-firmware-game combinations, the Steam Deck's controller will detect that a game is trying to use it, and switch from lizard mode to emulating a simple Xbox-compatible controller until the game is exited. While this precludes use of touchpads, gyros, and extra buttons that a basic Xbox controller would not have, it requires no configuration and may be preferred over more involved methods for some games.
sc-controller
You can use
sc-controller
as an alternative to Steam Input.
If the C0rn3j fork listed above gives you trouble with the right touchpad only working as a joystick mouse, or with the right joystick refusing to work in game, try the
kozec beta branch
.
This is useful if you wish to use complex profiles without using Steam, for non-Steam games, or as a fix for games that send double inputs.
You can use this while using Steam, just ensure the profile you wish to use is selected before launching a game. If you want to go back to the Steam driver, disable sc-controller from its GUI using the green "burger" button on the top left: if Steam is already open it will automatically switch.
Steam Input
Steam Input
can detect and remap the Deck's controls, complete with complex tools such as gyros and capacitive thumbsticks. If
Steam
is being used to run games, using it to also handle controller mapping may be desirable.
Even if Steam is not being used to run games, it can still serve a dedicated controller remapper – it will create a virtual Xbox-compatible controller under
/dev/input
that respects the mapping configured in the Steam client and can be used by any application. If Steam's role is limited to remapping controls, it can optionally be set to permanent offline mode, and in case of the
Flatpak
version, most permissions can be revoked.
OpenSD
Available via
opensd-git
AUR
, OpenSD is a highly-configurable userspace driver for the Steam Deck. It aims to be lightweight, very fast and provide a way to fully utilize the hardware. Configuration is done through text files and it provides a great user's manual.
Display
Orientation
On Wayland, the display and touchscreen work correctly in all orientations, without any tweaks. Depending on the model, the orientation may default to portrait but can be changed as normal in a desktop environment's settings.
On Xorg, a manual orientation fix may be needed depending on the display manager used. If the screen defaults to portrait, it can be rotated using
xrandr
.
$ xrandr -o right
The touchscreen can then be mapped to the proper orientation using
xinput
.
$ xinput --map-to-output 'pointer:FTS3528:00 2808:1015' eDP
To have this persist on reboots, create an
autostart
script.
Refresh rates
This article or section needs expansion.
Reason:
Check which rates are auto-detected on the BOE OLED, experiment with forced KMS on both Samsung and BOE OLEDs, experiment with EDID editing. (Discuss in
Talk:Steam Deck (Magyar)
)
The Steam Deck's display supports a wide range of refresh rates, but display managers will not auto-detect most of them.
On LCD models, only 60Hz is auto-detected, but 50Hz works well when
force-enabled via KMS
:
video=eDP-1:800x1280M@50
On OLED models with the Samsung display, 90Hz and 60Hz are auto-detected.
Brightness
If your monitor is unusually dimmed while booting, give priority to the vendor ACPI driver with a
kernel parameter
:
acpi_backlight=vendor
Gamut
The OLED models are billed as HDR-capable and have a much wider gamut than sRGB, but this causes sRGB-targeting content, including most games, to appear greatly oversaturated.
Fortunately, the display's EDID exposes fairly accurate color information, which can be used to good effect even without any calibration hardware.
GNOME
and
KDE
will automatically generate an
ICC profile
based on the EDID, which can be used with various desktop applications.
To set up the same color correction for games, run
displaycal
GUI on the Deck, tell it to generate its own ICC profile from EDID (this is recommended over re-using the profile generated by GNOME since that uses a newer version of the ICC format), then convert that profile to a LUT via DisplayCAL's 3D LUT Maker. This LUT can then be injected into games via
vkbasalt
AUR
.
The above was observed to give excellent results on the Samsung OLED. An
even better method
would be to tell
AMDGPU
to load the LUT into its color management pipeline, but while technical capability to do this is being adopted into mainline, documentation is scarce.
Fan controls
The Steam Deck's fan control can be enhanced by a daemon provided in Valve's
jupiter
repository, but are fully functional without it.
If you are using a mainline kernel, you need
patches from Valve's kernel
to expose the corresponding ACPI functionality, for example by installing the user-adapted
steamdeck-dkms
AUR
ACPI platform driver in
DKMS
form.
Battery limiting
If you leave your Steam Deck docked or with the charger plugged in, then it is worth to set a charging limit to a value below 100% to improve the battery life. Either valve's neptune kernel or mainline kernel with
kernel patch from valve
applied is needed (Example: using
steamdeck-dkms
AUR
). Then, limiting battery charge level can be achieved by writing the target limit in
/sys/class/hwmon/hwmonX/max_battery_charge_level
where
hwmonX
is  directory containing
name
file with
steamdeck_hwmon
written on it. Example for setting charge limit to 80 percents:
$ echo 80 | sudo tee $(grep -l "steamdeck_hwmon" /sys/class/hwmon/hwmon*/name | sed "s/name$/max_battery_charge_level/")
Tip
65% is the optimal charge limit
in terms of longevity
.
70 – 80% are more practical if you undock your Steam Deck at times.

Mimic SteamOS behavior
Note
Compared to a stock SteamOS install, Steam will be missing widgets to adjust "Framerate Limit" and "Thermal Power (TDP) Limit". See
Gamescope
and
AMDGPU#Manual
for how to make the same adjustments manually.
Auto-login
To set your system to automatically login without password, you can use any
display manager
and configure it to do so, for example
LightDM
.
Big Picture Networking
To enable Steam Big Picture networking support, you must use
NetworkManager
.
Steam client integration
You can launch steam with the
-steamdeck
launch option to enable fullscreen UI elements such as login and client updates.
On-screen keyboard
See
KDE#Plasma Mobile
,
GNOME on-screen keyboard
or
List of applications/Utilities#On-screen keyboards
for information on how to set up an on-screen keyboard.
Steam's on-screen keyboard also fully works, but Wayland will by design prevent it from interacting with other applications' windows. The
libextest-git
AUR
library can be injected into Steam to effectively remove this boundary, but this weakens the security inherently offered by Wayland.
