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.

You don't actually have to install nano first. You could also use gedit (or vim if you're brave enough) and save this file in the same place. Run this like:

sudo gedit /etc/rc.local

Ok gotcha thanks. Any idea why my joycons are connected and paired to bluetooth but they not working, i press L3 and no mouse. Do i have to run something in terminal?


If nothing else is installed on the microSD card on which your L4T Ubuntu installation resides on, your only option is to disable autoRCM (beware that this goes through the fuse check; if you're running on older OFW version and there are more fuses burnt than expected, your system won't boot). If you have Atmosphere or Kosmos Atmosphere installed, you can use their provided configs to boot into OFW, only this time it can bypass the fuse check.

Ok so i see rc.local create but now how do i make it executable? Following instruction for reboot2payload and it says to touch /etc/rc.local
I do but now what? How to execute?
Also any idea why joycons are connected and paired to bluetooth but they not working? I press L3 but no mouse. Do i have to run something in terminal? Sorry for all the questions since i'm new to linux.

For joycons hit l1 and r1 at the same time to pair them as one controller.
for rc.local: sudo chmod +x /etc/rc.local
then copy and paste the block of code you want inside it.
Also, it wont be needed soon anyway, as I am replacing that with a system service. and pushing it through the repo.

Ok i guess i'll wait for that service instead. And for the joycons i already hit l1 and r1 and they are paired (both have solid light) but what i mean is that after that joycons not working for me (even when i press L3 to use mouse, i get no mouse cursor) i re-flashed image twice but still no success. What i'm thinking maybe a bad download? Cause they do work when i flash the NOOBS4.img

 

[Gavin_Darkglider]

The download is good. That is because someone reconfigured the noobs4.img. it isnt official, and using joycons as a mouse isnt supported in l4t(By us at least, as it isnt stock configuration), that is handled by xorg configuration, or an app depending on the device. I have no idea, as for my build, I opted to use something that had joystick support, and I am using the much better touchscreen driver.

Hello.
I'm trying to connect a keyboard to my switch not docked but it does not work.

However, when I connect the switch to the dock, I can use the keyboard. Moreover, with lsusb(not docked), I see that the max voltage is 0ma, which does not look good.
I do not know if a linux command can answer the question.

Thank you in advance ^^

 

[jerry4on]

With update 1.3.1, the docking feather doesn't work. NS OS is 9.0.1
Anything else I should know to let the HDMI work ??

Are you using an official charger and dock?

Ok, I'm thinking of buying a switch and would like to know the current state of Linux at the console. Would you guys mind answering little questions? Be free to point out a reply if the question is already answered in the thread.

- I got a little confused about the updates. The main post says the last version is 1.3.1, but someone linked a 1.5.0 update some posts ago. Is it an unofficial update or what?

- Beside Lakka and L4T, do we have any other (maintained) Linux project for switch?

- How good is the Linux support? I would mainly use it for web and python coding. (does vs code got arm builds?)

- Is instaling retroarch on L4T the same as using Lakka or does Lakka have better emulation support?

- Do we got some fix for USB OTG and wired joyscons to works?

Thanks.

1. I dont have access to update op, so I posted the update where I could, but the latest official update is 1.5.0. As the person that released it, and a member of switchroot, I can say it is totally worth the update.

2. Yes. We have working Arch and Gentoo, which both have repos for the switch, but you have to build yourself, and doesnt have support for a lot of the nvidia features like Cuda and OMX.

3. It preforms fairly well. Will preform much better once I get the new kernel to work. If I cant, I will update the version it is running with the latest drivers, to at least get almost similar support for the hardware. I am in the process of trying to get the new kernel working with linux.

4. Lakka uses the crap joycon rail driver, and has no bluetooth. I am told l4t-ubuntu also preforms better with some emulators, but I dont know for certain, as I havnt tested this my self.

5. OTG doesnt work, because we dont know how to turn on power to the usb port. Wired joycons work, and have worked since before l4t-ubuntu, but the driver was crap, and broke bluetooth, so it was left out. We have a much better driver that works hand in hand with the wireless driver, so the disconnect should be seamless like HOS.

6. There are also updates for the Touchscreen, LP0(Deep sleep), internal IMU, ambiant light sensor. Which would leave NFC in controller, IMU in controllers, and IR camera/blaster in controllers, which will probably never come.

1. That's nice! Do I still need to manually apply all updates one by one?

3. Does the sd speed affect too mutch the performance? As far as I understand, the whole system will be running on it. Which sd speed would you recommend?

5. Hm... so would the OTG works when connected to the power using one these switch USB-C to USB/HDMI/Power supply? (dunno if I can post store links here, so image attach)
Also, I don't mind using joycons Bluetooth, but will joycon Bluetooth still work when attached to the console? Using it unattached in public locations would be pretty annoying and dangerous.

1. no, just install 1.5.0 and follow the instructions for 1.4.0 to get reboot2payload working.
2.. Yes, Samsung evo cards seem to work the best, though if I can ever get the new kernel working, it shouldnt be an issue anymore.
3. Only the official dock is supported for usb host mode at the moment. If it isnt the official dock, it is a 50/50 shot.

 

[jerry4on]

Are you using an official charger and dock?

Yes, it's the official dock. But HDMI won't work, even if I unplug and plug HDMI cable again.
I also tried to apt update && apt upgrade, still doesn't work.

Any input are welcome.

 

[Shahaan]

Probably a dumb question, but is it at all possible to get modern games (Burnout Paradise, GuiltyGear Xrd) to run through wine?

Not at playable speeds due to qemu emulation.

Your best bet would be to use Moonlight game streaming.

Thanks the contribution, I'm using L4T 1.3.1, apps run smoothly (with SanDisk A2 microSD).

Why is it not up on https://download.switchroot.org/ ?

Im new to the modding community so can somone give me an idiots guide on how to do this.

I looked at YouTube to compared Ubunta and Lakka and Switchroot. Which is so much better ?

Good going. I hate some people here are cunts. I wonder why are they here if they are not being nicer to newbies. We are all family here. Sad.
