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 option 3 didn't work...
I'm starting to believe that during the initial expansion of the SD card the switch may need to reboot and there is a problem with Auto RCM.
Do someone of you have Auto RCM active? and are able to make this work? I'm asking just to cross out also this option.

Yes i have Auto RCM on and it work's.

OK, so after messing around with Qjoypad I figured it was highly outdated and looked for something else.
Turns out the simplest way to control mouse with joycon is to do:
sudo apt install xserver-xorg-input-joystick
and reboot!
Voila!

p.s 'A' is left click and 'X' is left click. I am pretty sure the sensitivity can be altered through mouse settings.

i use 2 days no even single issue with wifi

What was the point of this reply? We are clearly having issues with our wifi. Is there something you are doing to not have such an issue?

 

[cm0ski]

Darn, OpenMW doesn't work. The openmw-wizard works just fine but openmw-launcher crashes on start.

 

[De4dm4sterBR]

Well, i've done a "zero fill" on my SD card, just to make sure it wasn't any errors that are preventing L4T from booting, and changed nothing. Still with that f** black screen.

So I really don't know what is going on on my switch. I did everything that is wrote in the tutorial.

Same here! I dunno how to overcome this problem. Can this be connected to the firmware version I'm running on my Switch ? I'm on 8.0.1, upgraded the other day.
Atmosphere is running smoothly though. Is this linux firmware dependent ? There is anyone here that is able to run it on 8.0.1?

i'm on 7.0.1, but it has nothing to do with firmware, you know, things you push to switch in RCM mode are just using the hardware itself, Horizon OS stays on internal NAND without beeing touched.

If anyone else is trying to run OpenMW, it seems running the launcher with this command "DBUS_FATAL_WARNINGS=0 openmw-launcher" will make it run. OpenMW runs great!

For qjoypad you open the terminal and type

sudo apt-get update -y and hit enter

then this

sudo apt-get install -y qjoypad and hit enter

then to configure it, make sure your joycons are paired, then in the terminal type

qjoypad --notray and hit enter

A controller icon will appear, click on it to configure the controllers

I have a question for both of these utilities.

Is there a way to map a hotkey or something that tells the OS to stop using the Joy Cons as a mouse? For example you'd use the Joy Con as a mouse to navigate to Dolphin, change settings, launch a game, etc, then press the home button to kill the mouse so you can use the Joy Cons as a controller. Then when you're done with Dolphin, press the home button and the Joy Cons will start functioning as a mouse again. Is something like this possible?

 

[bylaws]

New to this and I cannot get wine because it says I'm not connected to the internet. Also, I can't get dolphin because I guess I'm just stupid and it's really finicky.

Switch is arm, wine doesn't work

 

[hallo23]

So regarding Dolphin
I cloned the github from https://github.com/Tinob/Ishiiruka
How do I install it now?
Can someone please give me a step by step tutorial?

the repo has instructions on how to build it

also run this to get all the dependencies:

It's what I though. But then I can't explain myself why my switch won't run this Linux image.
I previously ran other versions of linux on this console on the same SD card.

so guys I installed kodi and when I rebooted instead of showing ubuntu it shows kodi and the exit button doesnt work can someone help me please

 

[Deleted User]

Anyone found a solution to the retroarch segmentation fault: core dumped error?

 

[tabzer]

I couldn't figure a way around this. I figured out how to exit Kodi, but logging in again booted it back up. Can't use the keyboard or mouse either. It's a trap! I ended up reimaging.

 

[uyjulian]

use lldb or gdb to get a backtrace

 

[enderer]

Is anyone having an issue with the wifi disconnecting?

if you mean horizon wifi, then yes. i've rebooted and tried different payloads. the wifi says it connects successfully (horizon) but then gives me some error about certificates. this only happened after messing with l4t.

that’s because of the clock desync stuff
