I tried installing the "noob" version a couple times in different cards and never got it to boot. No idea why I did that since it really isn't much easier.

Upon getting the switchroot image and the 1.5 update (cause why not be bleeding edge,) it boots no problem on a card that only black screened before.

Other items I noticed:
1. Touching the top menu doesn't work. Like ever.
2. Uninstalling stuff via the software menu (like libreoffice) while connected to a network resulted in it reinstalling after it uninstalled. No idea why. Disconnected and it worked.
3. Sudo apt-get upgrade looks like it says almost everything is no longer required and can be autoremoved. This can't be normal.....
4. Touchscreen freezes up on me randomly.

Haven't tried playing with joycons yet and still need to resize the partition and add a swap file.

Any one have directions to dual boot atmosphere? Seems like another boot folder on the same fat32 would conflict. Unless hekate can recognize another fat32 partition?

Yeah, their were some sdcard fixes for u-boot included in the 1.5.0 update I didnt document, because I didnt think they would make a difference after the kernel booted. I am happy they got you up and running though.

Gentoo and Arch are done(At least basic hardware support) Just waiting on me to get off my ass and release them. lol. I will bootstrap debian next, which should go stupid quick(and have full hardware support like ubuntu). That being said, I am currently waiting on my sdcard RMA from samsung, so development has come to a halt for me until that comes in. As for the rest of the hardware support for arch and gentoo, it is a matter of installing debs from jetpack, which is the easy part, as most of that is just extract and place. lol. It is just the idiosyncrasies between distros. lol.

Glad to hear you're working on a Debian port. I started creating my own with debootstrap but never got around to finishing it, and I know I'd get stuck with the drivers. I already run Debian arm64 on a bunch of other boards as well as my desktop/laptop systems so I'll definitely be switching to it on my Switch.

is there any way to dual boot android and ubuntu in switch ?

Conan179 · Oct 11, 2019

Yes, with edit the boot.scr.

L4T Ubuntu 1.3.1

Intro
L4T Ubuntu is a version of Linux based on nvidia's linux for tegra project. It uses a different kernel compared to previous releases which allows it to use features not yet in mainline. Such as audio, docking support and vulkan.

Beware, using high clocks in handheld mode will degrade your batteries capacity a lot faster than at stock clocks
If you can't install an application check this thread, and ask all questions there https://gbatemp.net/threads/l4t-ubuntu-applcation-install-guides.537579/

Features

Dock support with USB

Bluetooth (both controllers and audio)

Nvidia GPU drivers - Vulkan and OpenGL

Audio - Headphones, speakers and over HDMI when docked.

Joycons and pro controllers are supported fully when not attached to the the console

Touchscreen

Display

WiFi

CPU frequency scaling - The CPU scales from 200mhz to 1.7ghz (what switch is binned for) depending on the load its under. Fans are adjusted to account for this

Full sdcard speed

Hardware video acceleration when using the built in videos app (means you can watch videos without battery draining massively)

Prerequisites

A dedicated 16GB+ sdcard

Added SLEEP support (press power button), note the device may randomly wake up and log out if sleep is activated while logged i n, if this happens to you please ssh in and upload the contents of /var/log/syslog .

Sped up sdcards, broken ones still wont work though.

Charging now happens faster.

Probably more stuff I can't remember.

1.3.1

Reduced battery usage in sleep

How to install

Download the image from the downloads section and extract.

Write it to your sdcard using a program such as etcher or dd

Apply any updates from the updates section in the thread, IMPORTANT as images don't EVER come with them

Boot hekate and select L4T from the configs menu.

Wait for around 2-4 minutes while it initially loads

Go through the setup process - make sure not to dock the console in this period.

Once the initial setup is finished and you are on the login screen it is advisable to reboot:

Hold the power button for 10 seconds.

Load hekate again and select L4T as a payload.

Log in and open the "Disks" app

Select the second partition of your sdcard and click the gears icon

Choose resize and change the size to the full amount of available space.

Enjoy, you now have fully featured Ubuntu on your switch!

Bugs

Wired joycons do not work (connected to console)

Docking while having a ssh session open can cause the display to not turn off correctly

USB OTG - works fine in dock though

Vulkan is buggy in dolphin

Touch randomly freezes sometimes

The real time clock gets messed up in horizon

Misc Info

Pair (joy/pro)cons by opening the bluetooth menu in settings and pressing the + button in the bottom left corner. Then press the sync button on the controller and select its name in the pairing window. Once both joycons are paired press each of their shoulder buttons to use as one controller

To update the system run "sudo apt update", "sudo apt upgrade". This will apply all switch and ubuntu updates aside from kernel updates, they will be posted here if ever needed.

To limit cpu freq, run cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies. Find the one you want, then run: echo <freq you want> | sudo tee /sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq

To force max freq run echo performance | sudo tee /sys/devices/system/cpu/cpufreq/policy0/scaling_governor

A gui to configure overclocks and fan profiles is coming soon

NEW: To activate 2 ghz mode run

Code:

echo 1 | sudo tee /sys/kernel/tegra_cpufreq/overclock echo 2091000 | sudo tee /sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq

then run the command to force max freq if you want to use anything intensive.

To always use 2.0ghz mode copy

Code:

#!/bin/bash echo 1 > /sys/kernel/tegra_cpufreq/overclock echo 2091000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq exit 0

to /etc/rc.local (you'll need root to create)

use another SD card

Gavin_Darkglider · Oct 12, 2019

LP0 is working. It only took 180 Days, and hours of stairing at code for coreboot/atf, but it all payed off in the end.

Will push fixes later today so stay tuned.

Nothing wrong with your switch, just the sdcard driver in the kernel. Use a samsung evo card, and it should work.

But YEAH. LP0....

Heroic

Gavin_Darkglider · Oct 13, 2019

So, this LP0 stuff is taking longer than anticipated, for some reason ubuntu wont wake up.

It works on my gentoo build quite nicely, so I am not sure what is going on with ubuntu.

stick267 · Oct 13, 2019

LP0 is deep sleep, correct?

stick267 said:

Yes, lp0 is deepsleep, unfortunatly, something about ubuntu is breaking it. So, I am working on porting ubuntu 18.04 from the nvidia samplefs to see if it makes a difference. Arch is having the same problems, so I dont know why it works *perfectly*(with a few workarounds) in gentoo.

Gavin_Darkglider · Oct 16, 2019

So, no change with sample root from nvidia.

DominoBright · Oct 22, 2019

Dang, guess deep sleep will take a while if it ever comes.

This has done so much to prevent me from installing Flash, while using Cinnamon makes the touch screen inputs hit other spots. (A rotation thing. I suppose that's fair though, it's made for Unity.)

Gavin_Darkglider · Oct 23, 2019

Deep sleep issue has been found, and is being worked on as we speak. New touch driver should fix your issues there, rotation isnt working for me in rel30, probably something stupid I missed. lol. Ambiant light sensor is working though, and I am waiting on new joycon rail driver. Once that is done, and deepsleep issue is fixed, I will push an update for ubuntu, but really, I want to push a new image all together, because there are a lot of things userspace side of things that need to change to make everything work properly. Dont worry ubuntu people I havnt forgotten you.

Great news. I wasn't aware that a Joy Con rail driver was being worked on. Will the updated image include reboot to payload as well? Either way, I can't wait for it. Thanks for all your hard work.

Good that there will be a new image coming out. It will save me from having to download and apply multiple updates at once.

DominoBright · Oct 23, 2019

Oh sweet! I'm all for a new image myself if it means a better overall experience.
