THIS GUIDE IS DEPRECATED
THIS IS BETTER https://github.com/natinusala/painless-linux

I've successfully booted ArchLinux using ShofEL2. Here is a quick guide on how to do it - I'll assume you're computer literate and know how to use a terminal / Linux commands / git.
Everything is taken from the README of the ShofEL2 repo so if you want to go even faster, go read that instead.

Thanks to NightHammer1000 and Y2K-x for the help !

There is a simplified and faster version of this tutorial available here, with precompiled binaries so you don't have to build everything : https://github.com/SoulCipher/shofel2_linux

What works / what doesn't

• Desktop environment : Gnome, LXDE, KDE
• Wi-Fi : works
  • You will need to reboot your Switch and run the exploit again to make the Wi-Fi work (it never works on the first boot)
  • Then enter the Network Manager Application and add your network from there
  • If it doesn't work, you will need to edit the configuration on the host computer (see the additional notes at the end of this post)
  • With LXDE : Can cause a kernel panic if used at the same time as Bluetooth
• Bluetooth : works but Joy-Cons can't be paired
• Touch screen : works, although LXDE is not very touch-friendly
• Audio : doesn't work yet
• GPU acceleration : works (via mesa), with OpenGL (and maybe Vulkan too ?)
• Joy-Cons : not recognized
• Volume buttons : working with Gnome but not doing anything since there is no audio device
• Power button : doesn't do anything, no sleep mode, no graceful shutdown
• USB : doesn't work
• Dock : not tested yet, but I bet it doesn't do anything besides charging the battery
• Power management / battery level : working with Gnome

What you'll need

• A computer running Linux with a blue USB SuperSpeed port, or a Mac
  • A Linux VM can work in theory, but it depends on how the USB passthrough is implemented (apparently VMWare works, VirtualBox doesn't)
• A USB A-to-C cable (with data support, obviously)
  • be careful as cheap cables were reported to work randomly / not work at all
• Some time (you know, Linux is kinda large)

Prep work

First, you'll need to install the required toolchains. Open this link and download the tar.gz binaries for

• aarch64-linux-gnu
  
• arm-linux-gnueabi

Be careful to choose the right architecture for your PC (for me it was x86_64 so "gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabi.tar.xz").

Once you have them, extract them somewhere nice and add the "bin" (not "lib" as I previously stated) folder of both toolchains to your PATH ("$ export PATH=$PATH:/path/to/toolchain1/lib:/path/to/toolchain2/lib"). The building process won't work otherwise.

Then, install those dependencies (how to install them and their name might depend on your distribution) :

• build-essential (sorry I didn't add it it was obvious to me)
• libssl-dev
  
• swig
• bison
• pkg-config
  
• flex
• zlib1g-dev
  
• python3
• python-dev
  
• python3-pip
• pyusb 1.0.0 : "$ sudo pip3 install pyusb==1.0.0"
• libusb-1.0-0-dev

Compiling

Clone each required repository :

$ git clone https://github.com/fail0verflow/shofel2.git
$ git clone --recursive --depth=1 https://github.com/fail0verflow/switch-coreboot.git coreboot
$ git clone https://github.com/fail0verflow/switch-u-boot.git u-boot
$ git clone --depth=1 https://github.com/fail0verflow/switch-linux.git linux
$ git clone https://github.com/boundarydevices/imx_usb_loader.git

You can grab a coffee or two because Linux has more than 5 million files to download.

Then, build everything :

$ cd shofel2/exploit
$ make

$ cd u-boot
$ export CROSS_COMPILE=aarch64-linux-gnu-
$ make nintendo-switch_defconfig
$ make

$ cd coreboot
$ make nintendo_switch_defconfig
$ make iasl
$ make

If you have a tegra_mtc.bin file error, you'll have to extract it from a Pixel C stock image :
"$ ./build/util/cbfstool/cbfstool bootloader-dragon-google_smaug.7900.97.0.img extract -n fallback/tegra_mtc -f tegra_mtc.bin"

Or you can download it directly from here : https://0w0.st/tegra_mtc.bin (thanks to @CptPotato for uploading this)

You'll have to put it in the "coreboot/src/soc/nvidia/tegra210" directory.

$ cd imx_usb_loader
$ git reset --hard 0a322b01cacf03e3be727e3e4c3d46d69f2e343e
$ make

The big one :

$ cd linux
$ export ARCH=arm64
$ export CROSS_COMPILE=aarch64-linux-gnu-
$ make nintendo-switch_defconfig
$ make

If you encounter issues about a missing rule "/lib/firmware/nvidia/tegra210/vic04_ucode.bin" for the target "firmware" you'll have to :

• install the firmware-misc-nonfree package
• if you can't install it, or if it still doesn't work, download the package manually from debian sid and extract the file "/lib/firmware/nvidia/tegra210/vic04_ucode.bin" (from the root of your PC, not on the cloned repo) from the DEB (and chmod it if needed)

If you encounter issues about a missing rule "/lib/firmware/brcm/brcmfmac4356-pcie.txt", download this file and put it in "/lib/firmware/brcm/" (from the root of your PC, not on the cloned repo)

Building the rootfs

This is the annoying part. Download the archive / image corresponding to the distribution you want to use :

• Stock Arch Linux (useless without UART, you can't even log in) : http://os.archlinuxarm.org/os/ArchLinuxARM-aarch64-latest.tar.gz
• Arch Linux with LXDE and touch screen support (credits to @Gigaa) :
  • Without hardware acceleration : https://0w0.st/rootfs.tar.bz2
  • With hardware acceleration : https://0w0.st/rootfs2.tar.bz2
  • With hardware acceleration, Chromium and sudo : https://drive.google.com/open?id=1VIH3GWtBrM4uuVQOQopASYZy4x3Jw1Uv
• Arch Linux with Gnome (credits to @00Cancer) : https://0w0.st/gnome__rootfs.tar.bz2
• (Recommended) Arch Linux with KDE and GPU power management service (credits to @Gigaa) : https://0w0.st/KDE_rootfs3.tar.bz2
• Ubuntu 18.04 (you'll have to build the image yourself) : https://github.com/cmsj/nintendo-switch-ubuntu-builder

If it's a tarball you just downloaded

While it's downloading, you'll have to take a microSD card and, using the software of your choice (I used GParted) :

• remove every existing partition to only have unallocated space on it (do I need to tell you that you're going to loose everything on the card ?)
• create a tiny FAT32 partition (I chose 200mb but it doesn't matter) - that'll be mmcbkl0p1, you can label it "garbage"
• create an ext4 partition on the remaining part of the card - that'll be mmcblk0p2, you can label it "rootfs"
• it's important that the FAT32 partition comes first and the ext4 one comes after - on the Switch, Linux will look for mmcblk0p2, the second partition, if you have scrolling boot logs and then back to RCM it means you did it wrong

Once the rootfs tarball is downloaded, you can simple extract it to the mounting point of the ext4 partition you just created :

$ tar xvf ArchLinuxARM-aarch64-latest.tar.gz -C /mounting/point/of/ext4/partition && sync
$ cp ArchLinuxARM-aarch64-latest.tar.gz /mounting/point/of/ext4/partition/root && sync

("/mounting/point/of/ext4/partition/root" is the "root" directory on the partition)

Don't forget to properly eject the SD Card !

If "tar xvf" doesn't work for you you can install "bsdtar" and use "bsdtar -xpf" instead

Then you can put the SD card in the console.

If it's a img / bin file you just downloaded

You can simply write it on your SD card using :

• If you're on Windows, Ether or Win32DiskImager
• If you're on Linux / Mac OS : "sudo dd if=yourimage.img of=/dev/sdX && sync" where /dev/sdX is the device of your SD card (unmounted)

You will probably want to open a partition manager to resize the ext4 partition once it's flashed, so that it fits your SD card.

Then you can put the SD card in the console.

Booting linux

Run the exploit :

$ cd shofel2/exploit
$ sudo ./shofel2.py cbfs.bin ../../coreboot/build/coreboot.rom

Your terminal should now be waiting for the Switch to enter RCM mode.

To do so : (I don't have pictures but that's the same method as fusée gelée, just look at some video tutorials)

• plug the Switch on your PC using the USB A-to-C cable - use a blue SuperSpeed port if you have one
• shut it down
• remove the right joy-con
• using a method of your choice, short the 10th pin of the right joy-con (the last pin on the right, away from the screen, closer to the back) with the ground : that can be pin 1, 2 or 7, that can also be a screw on the joy-con rack or the console's fan - I personnaly stick a RPi jumper wire in the fan and touch the 10th pin on the other side, works everytime (like this)
• keep the pins shorted and power the Switch while pressing the volume UP button

If it worked, the console will show a black screen and you'll see the exploit running on your terminal. If you see the Nintendo logo, it has failed. You can power off the console and try again.

Then, run those last commands :

$ cd shofel2/usb_loader
$ ../../u-boot/tools/mkimage -A arm64 -T script -C none -n "boot.scr" -d switch.scr switch.scr.img
$ sudo ../../imx_usb_loader/imx_usb -c .

Linux should then boot on your console - first the boot logs with the penguins, and then an ArchLinux login prompt. Voilà !
Again, if you have the boot logs and then a black screen, it means you did the SD card part wrong.

Additional notes

Hardware graphics acceleration

The most recents image already contain this fix.

To add mesa drivers install this package using pacman :
https://0w0.st/mesa-full-tegra-r101876.bf5e0276b6-1-aarch64.pkg.tar.xz

You will need a working internet connection to do so.

Then, use this script to choose your power profile : https://0w0.st/power.sh

Full speed RAM

According to the blog post ("Linux on Switch boot chain" section), you need to extract a file from a Pixel C factory image in order to have the RAM working at full speed. I didn't do it so I won't cover it here.

Fixing calibration issues of the touch screen (thanks to @Wizardy)

To fix calibration issues of the touch screen, edit the file /usr/share/X11/xorg.conf.d/10-evdev.confg (of the rootfs)

And change the InputClass section to :

Section "InputClass"
        Identifier "evdev touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
        Option "InvertX" "no"
        Option "InvertY" "yes"
        Option "SwapAxes" "yes"
        Option "Calibration" "0 1279 0 719"
EndSection

Wi-Fi

To setup Wi-Fi, mount the rootfs partition on your host PC and edit the configuration for your network in the file "/etc/NetworkManager/system-connections" (if it doesn't exist, take Gigaspot).

To have a working Wi-Fi you must reboot your Switch and run the exploit again each time you power it off

Moving the rootfs to another partition

If you want to move the rootfs to another partition on your SD card, edit the "shofel2/usb_loader/switch.scr" file and replace "/dev/mmcblk0p2" by the partition you want to use.

i dont know what you mean, my english and stuff is very bad

In Gparted, pick Devices, Create partition table, msdos and create. Do remember that this deletes everything on the card. and yea ofc, remember to run sync after you used tar.

ty @Gigaa <3

That's awesome, be aware that bluetooth and wifi doesn't go well together just yet. It might crash.

Ohhhhhhhh i forgot to use sync i see now. im dumb

 

[Gigaa]

Remember to eject the media before removing the micro sd, also, check activity light on sd card reader, im running ubuntu in a vm, and it's still technically writing long after terminal window claims it's finished copying.

Anyway, Giga, original image works for me, Wifi worked (after doing shut down (NOT restart) and re-exploit without restarting switch), bluetooth worked too, but my bluetooth keyboards battery was too low to know if it works reliably or if it's flakey.

One thing that is definitely flakey about the initial build you posted is the touchscreen, im getting detection before the fingers actually made contact with the screen, making simple things like double tapping to click not really feasible.

How difficult would it be to mess with it to make double tap act as left click and long-press act as right click?

This might be down to the desktop environment i picked. lxde is not very touch friendly. Now that the hw acceleration package have been posted you should be able to install kde or gnome.
I haven't test this yet so it might not work tho.

 

[natinusala]

Actually thats correct point @natinusala @Gigaa It might be that people have issues with creating rootfs cards because of sync issues.
I would suggest adding sync command after first tar command so everything would be ok. Seeing many people here who exactly have no linux skills and doing that step by step they miss some things which are obvious for other linux users.

Oh shit I forgot about this ! I'm going to add it

 

[Eastonator12]

I don't know what error you're getting exactly, nor what it means from just that description. Do you have a more complete version of the error message?

Just for reference here is what I did to partition my SD card and put the rootfs on it:

   Start fdisk to partition the SD card:

      fdisk /dev/sdX

   At the fdisk prompt, delete old partitions and create a new one:

      Type o. This will clear out any partitions on the drive.

      Type p to list partitions. There should be no partitions left.

      Type n, then p for primary, 1 for the first partition on the drive, press ENTER to

          accept the default first sector, then type +100M for the last sector.

      Type t, then c to set the first partition to type W95 FAT32 (LBA).

      Type n, then p for primary, 2 for the second partition on the drive, and then press

          ENTER twice to accept the default first and last sector.

      Write the partition table and exit by typing w.

   Create the FAT filesystem:

      mkfs.vfat /dev/sdX1

   Create and mount the ext4 filesystem:

      mkfs.ext4 /dev/sdX2

      mkdir root

      mount /dev/sdX2 root

   Download and extract the root filesystem (as root, not via sudo):

      wget http://os.archlinuxarm.org/os/ArchLinuxARM-aarch64-latest.tar.gz

      bsdtar -xpf ArchLinuxARM-aarch64-latest.tar.gz -C root

      sync

   Unmount the partition:

      umount root

   Insert the SD card into the Switch and run the exploit and usb-loader commands.

Modified from the instructions found for the Raspberry Pi here: https://elinux.org/ArchLinux_Install_Guide#Flashing_the_Image

You've done all of this, correct? (It doesn't have to be the same way I did it, just an equivalent one) Also, you may need to do it again after you changed the partition table of the SD card back to MBR.

i have followed your instructions until bsdtar. my pc with a sd card reader is booted off a live usb, and it just DOES NOT want to install libarchive. when i try to install bsdtar, it tells me to install libarchive-tools. but when i try to do that, it tells me it can't locate that package. what should I do?

 

[gbazone]

Can I inject LXDE or other things into the precompiled binary? (https://github.com/SoulCipher/shofel2_linux) I just DD'd it onto my SD card.

 

[spotanjo3]

I wonder if this linux on Switch can play PS2 emulator at decent speed ? I doubt.

 

[EIREXE]

I got @Gigaa 's build working, however it appears it justs sits at the login shell, anything else I have to do?

do you have a USB C OTG cable? you could use that to login

 

[EIREXE]

do you have a USB C OTG cable? you could use that to login

Isn't the LXDE login supposed to come up?

 

[EpicLPer]

do you have a USB C OTG cable? you could use that to login

USB C OTG doesn't work yet.

lxde and other packages goes into the rootfs, not the kernel.

 

[Eastonator12]

did you install the version with LXDE? if you did then yes it should
