Install went just fine , but now i need help ... any clue how i could make the fat32 partition bigger ? because i would like to use Linux , Lakka , Emunand on one SD Card it should be possible i guess

@Refriger8tor is 1GB enough for the swap? because the minecraft map i host needs 4gb of allocated ram

--------------------- MERGED ---------------------------

and i have a 64gb sd card so the swap can be big if needed

There's a guide in the first post of the application install help thread linked in the OC

And there is also a way to run java edition MC on L4T Switch

swap works fine

I come bearing gifts today. If, you like me, do not like the behavior of dock removal, such as the console screen resolution being off, with this version of dock-hotplug, that is a thing of the past.

1. Download the attached script.
2. as root move script to /usr/bin/dock-hotplug
3. Open terminal, and type chmod +x /usr/bin/dock-hotplug

Now removing from the dock should result in screen resolution returning to 1280x720 resolution every time. In my gentoo build, I have 6 dock profiles to choose from, and easy switch using eselect. I also added disabling the touch screen when on dock(Assuming you are using a non dual screen dock-profile), which is as simple as adding xinput <enable/disable> 6(id number assigned to touch screen)

This is going to take forever, as the data all has to be moved to extend the partition,

This is how I would do it:

1. Copy the switchroot img.gz to a flash drive(Assuming you arent already running linux)
2. gunzip switchroot img.gz
3. type into root terminal: kpartx -v -a <path to extracted img>
4. partition sdcard with fat32 partition the size you want, and create the second partition formatted to ext4 to use the rest of the drive(we will need to resize it later.)
5. close partition editor
5. extract switchroot update 1.3 to fat32 partition.
6. type into root terminal: dd if=/dev/loop<# assignedbykpartx)p2 of=/dev/<sdcardPartition2> bs=4M sync=conv
7. type into root terminal: kpartx -d <path to extracted img>
7. reopen gparted, and resize the partition how you like, then create more partitions, if needed.
8. mount the partition and make sure it works before putting it in the switch.

If you searched this thread, you'd find this:

If you have 2 SD cards, and an official Nintendo dock, install L4T to two SD cards. Boot Linux on your Switch, and insert your 2nd SD into a USB SD card reader, and plug that into your dock's USB port. Now install/use gparted on your Switch, to resize/move the ext4 and fat32 partions on your 2nd SD card. This resized SD card will be your full, permanent, L4T + Lakka card (this is how I got Lakka and L4T on the same SD card).

When can we expect hw acceleration in Firefox? I strongly dislike chromium.

Firefox should perform about the same as chromium. HW accel doesnt work on any browser on L4T

When you want to compile a version that supports the hardware acceleration in the switch. I havnt looked into it yet, but I know there is a version of chromium that has openMax acceleration, which is what I would search for for firefox.

So does mupen64 work fine through retroarch? If it does, what is the code to get retroarch? I know that the install guides has a piece of code for retroarch but that is outdated (at least I don't know if it is).

If you haven't already flashed an image you can grab mine with retroarch and other emus already installed on my thread. Otherwise those instructions should be fine but keep in mind it's the experimental nightly retroarch so it might not always work.

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)

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)

Can this mess up my battery or break my screen? I heard somewhere that it could do that.

You will probably not get any guarantees, but so far I did not spot any reports of unrecoverable battery or screen issues due to L4T.

This was with the very first Linux version that came out, it doesn't happen anymore now. Only thing it derps up is the time but that'll correct itself again once you boot back into Horizon OS since it grabs that over the internet.

Chances are it still writes the register that messes up the battery. If it doesnt, then the version of u-boot being used probably does. I havnt seen any sources for U-boot on switch root, so they are probably using the version from FailOverfl0w. That being said, hekate fixes the register automagicaly when you boot the latest version, so it isnt a big deal. As for screen issues, I have been running linux mainline 5.0 since october, and before that I ran tardyp's 4.17 kernel, and FailOverfl0w's 4.15 kernel, and never had screen issues(excepting when a friends kid sat on it, while playing breath of the wild), and even that was minimal, and not really noticeable, unless you are looking at a black screen with the backlight on. lol. Nothing to do with linux though
