Frequency depends on the Nvidia Applet Power Mode, automatic Console and Handheld Profiles - Automatic Overclocking through the Nvidia (Blue/Red Joy-Con) Indicator Applet (select an OC mode)
- Full eMMC/SD speed. For SD, proprietary UHS DDR200 is also supported.
DDR200 support makes Switch the first device in the world to even support it. - Hardware Video acceleration
Support in new SMPV Player app (smpv), ffmpeg-l4t, mpv-l4t, system ffmpeg and the chromium-browser
Watch videos without battery draining massively and convert videos really fast - Deep Sleep
- IMU/Ambient Light sensor support
- R2P (Reboot to any hekate boot entry configuration)
- Support for Moonlight-QT
Stream games/desktop from your Nvidia (nvidia gamestream) or AMD (sunshine moonlight host) GPU to your Switch
HW video accelerated up to 4k - Widevine DRM support for Streaming platforms via Chromium
- Updates distributed through APT package manager
- Basically everything the hardware supports even if Switch OS doesn't support. Except NFC and IR.
¶ JoyCon and Switch Pro Controller native support:
JoyCon may be paired through Linux blutooth settings or through hekate to allow for use in HOS, Linux, and Android without the need to repair.
JoyCon function via Bluetooth, railed on Switch, and connected via USB through the JoyCon charging grip. Multiple pairs can be connected and be registered by pressing L+R or ZL+ZR. Otherwise if SL+SR is used, it will pair them in sideways orientation.
Switch Pro Controller functions via Bluetooth and via USB. You may pair through the Linux/Android Bluetooth settings but the pairing will not match HOS. To dump the pairing info for use on HOS and Linux without the need to repair follow these instructions:
- Pair procon in L4T Ubuntu once in order to create the needed files
- Pair it again in HOS
- On your Switch running L4T Ubuntu, connect procon with USB and run
jc-dump-ltkin the terminal to get the HOS LTK- Go to
/var/lib/bluetooth/{switch bluetooth mac address}/{procon mac address}/in your switch and editinfofile.
Under the section[LinkKey]you will seeKey=. Remove the contents after the = and paste the key you got fromjc-dump-ltkin there. Remove spaces in the key.- Reboot Linux. Now procon will be able to auto connect in both HOS and Linux.
Both JoyCons and Switch Pro Controllers have their IMU (accelerometer/gyro) exposed as udev inputs in Linux and can be used in games/programs with support (Dolphin-Emulator is a good example)
¶ Switch Docked Displayport/HDMI Output Support:
Support for Official Nintendo Switch Dock as well as 3rd party Displayport/HDMI adapters/docks/hubs exists in Linux/Android. Official Dock requires power input from the official power adapter or better (15V 2.6A+ and 5V 1.5A+ PD profiles required from the charger). Many 3rd party adapters/docks/hubs can be used without supplemental power or with power from a USB-C PD Power adapter.
Official Original Nintendo Switch Dock is capable of resolutions up to 4k 30hz or 1440p 60hz. OLED dock supports up to 4k 60hz. Some 3rd party adapters can also achieve these resolutions. (note, any non-OLED Switch hardware is INCAPABLE of outputting 4k 60hz)
To specify a custom resolution for docked mode (useful for using 1920x1080 60hz on a 4K display): echo "1920x1080" | sudo tee /etc/dock-hotplug.conf
The syntax is basically WIDTHxHEIGHT {optional xrandr settings}. For example 1920x1080 --rate 120 will select 1080p at 120hz.
¶ Switch USB-C OTG Support:
OTG via USB-C is enabled and devices can pull up to 1.3A when unpowered.
Powered OTG adapters are not supported, it is advised to use a hub/dock (which usually contains HDMI/Displayport) if USB and powering is desired.
¶ Switch Accelerometer/Gyro and Rotation Support:
Automatic rotation is supported in DE that have it enabled. The built in accelerometer/gyro is NOT exposed in userspace as a udev input.
Instead, it is mapped as an iio device along with the ambient light sensor and fan tachometer.
/sys/bus/iio/devices/iio\:device0/ -> Accelerometer
/sys/bus/iio/devices/iio\:device1/ -> Rotation/IMU
¶ Common Features and Applications
¶ JoyCon Mouse/Keyboard mapping:
Many users find it handy to map their JoyCons/Pro Controllers as a mouse/keyboard within Linux.
There are profiles pre-installed for Official Joy-Cons, Switch Pro Controller, GameCube Controller (Wii-U/Switch Gamecube adapter with ToadKing Driver), Dualshock 4 Controllers (wired only, for now), X-Box One Controller (Wireless Only).
The current JoyCon/ProCon mapping is
If you are used to other mappings, give the above a try for a full week.
It's based on the most common and intuitive gamepad mappings.
If you still can't get used to it, view the /usr/share/X11/xorg.conf.d/50-joystick.conf file for instructions on editing/writing/customizing the configuration to your own needs.
¶ RAM Scaling
RAM is automatically scaled and can reach max 1600 MHz.
Overclocking is supported by adding ram_oc= key in the .ini. Read README_CONFIG.txt for more, since the values must be precise.
Switch 2017 suggested max value is 1862400 KHz.
Switch 2019/Lite/OLED suggested max values are 1866000 and 2133000, depending on ram chips.
¶ Reboot 2 Config
An app called Reboot 2 Config was added in 5.1.0 in the Switch tray icon.
It allows you to reboot into your existing hekate boot entries with 2-3 taps.
¶ Widevine Streaming
Widevine L3 is supported for Streaming Movie and TV series platforms.
- For most platforms you can use the existing
Chromium Web Browser. - For others like Netflix, you use the
Chromium Streamingone.
¶ Nvidia Power Profile Applet (nvpmodel):
Multiple custom cpu/gpu power profiles are included with the switchroot bionic 3.2.0 and future releases.
Nvidia documentation for nvpmodel GUI can be found at the link.
The nvpmodel config can be found here by default at
/etc/nvpmodel/nvpmodel_t210.conf for Erista and
/etc/nvpmodel/nvpmodel_t210b01.conf for Mariko devices.
More configs can be added by following the examples within.
Current L4T releases include these profiles by default:
