L4T Ubuntu
​

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.

Also, is there a way to detect if the Switch is docked? I wanna write a bash script that enables overclocks when docked, but returns to normal when undocked. I assume there's some way to detect when a display is added/remove, but I don't do much bash programming so I wasn't sure.

If someone could upload their '/etc/nv_boot_control.conf' file here that would be great. I seem to have deleted my copy? Idk, I have 3 broken packages that say they need it. (nvidia-l4t-xusb-firmware, nvidia-l4t-initrd, and nvidia-l4t-apt-source)

There's no such file in that folder or any other folder.(I searched for it everywhere).

That's odd. It was saying that it couldn't read that file when trying to update those 3 packages. I thought it must've been deleted by accident, but I guess not. I guess I'll just try a fresh install of L4T since I haven't done anything important on it yet

Is there KVM support? It'd be interesting to test if a Windows 10 ARM VM works. I'm aware of Imbushuo's attempt to boot it, but as it's incomplete and I have no idea about implementing Tianocore EDKII it looks impossible for now.

Has anyone by chance happened to a get a USB ATSC device working?

Hey, it's me again. Has anyone tried using a pro controller to play dolphin emu? Mine says it's connected and paired under bluetooth settings, but dolphin says device not found when choosing input method for emulated wiimote

is ubuntu can run on sx lite?

I believe you would have to install a chip inside the switch lite to be able to boot into recovery mode. But other than that it should be the same as a normal switch. Someone correct me if I'm wrong. I don't own a switch lite

Not yet. Switchroot Ubuntu doesn’t support Mariko Switch devices yet.

Hello. I used this script,

https://github.com/lulle2007200/SwitchSDSetup/releases

to install L4T, Andriod, and emummc

I heard a new version of L4T Ubuntu released and my question is how can i update my existing version?

 

[bailli]

Very different topic:
I am trying to build a game which uses Haxe and Lime. For Haxe itself there exists a ppa which includes arm64 packages, and I guess I managed to compile Lime correctly (was a bit tricky as hxcpp does not really expect a Linux arm64 target). At least a few sample applications work.

However the application I actually want to compile crashes at startup with sigbus and running it through gdb suggests it crashes somewhere in the pthreads library.

Has anybody expierenced something similar? It might actually be a bug in pthreads as googling showed that this happens on non x86 platforms...

Hekate just tells me that it can't find the install files when I put them on the FAT32 partition I created in Hekate. What am I missing?

EDIT: Nevermind. Copied the files over to the SD again and now it's behaving as it should.

Now I just have to figure out if there is any way to resize the 7GB install partition that Hekate created, back into the Ubuntu Ext4 partition. You'd think it would be easy, but since the partition is first on the partition table; before the Ubuntu partition, there are some limitations to creating, removing or resizing partitions to the left of another partition without causing errors or data loss.

I can't update anything or install anything using sudo apt says i got an error in source.list this is after a fresh install.

Hello, I just tried to update from 3.02 to 3.20 L4T and after following the 4 step instructions, on the 1st post, launching Ubuntu kicks right back to Hekate. Happens pretty fast, right after showing the switchroot logo. I was able to reverse the procedure and get back to 3.02 just fine. Wondering what I did wrong? Thanks in advance.

 

[Quattro74]

I just needed to make one change in one config file, uenv.txt, and I was able to get to the desktop. I am using the premade multiboot image from psxtools.de

 

[Quattro74]

It seems the special order of the partitions on the psxtools.de image is breaking my reboot2payload out of Ubuntu. It wasn't working b4 the upgrade to 3.20 either, they ship the same boot.scr with their sd files for ubuntu as come with the update to 3.20. I just get to RCM mode when I reboot. Soo I should be looking at editing my boot.scr ?? Anyone have a newb guide for that? Thanks!

 

[bakedbeans]

How much of the switch special treatment has been submitted and hopefully merged in the upstream mainline kernel?
Various other console linux ports never made it there

I made the image files.
The psxtools image is made for ArgonNx.
I add another reboot to payload file inside Ubuntu.
Add the 3.2 updatec And change the uenv.txt
Change the rootdev to emmcblk0p8

Or pull the update file from ams plus and pick the Ubuntu folder from the zip and copy it to your SD card.
