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.

Hello,

Is there any way to configure the switch joycons on retroarch without using a keyboard? Right now i can only scroll through the main menu on retroarch but i cant click anything

If its not an OS related issue, try to post over at https://gbatemp.net/threads/l4t-ubuntu-applcation-install-guides.537579/ that seems to be where application help is going on at. You need to configure whatever controller your using inside of RA. Settings > Input > User 1 Binds > (change seetings accordinly) > User 1 bind all.

Should be done.

Can someone confirm whether moonlight game streaming is performing reasonably well in this Linux?

I am trying to get the "HORI Nintendo Switch Multiport USB Playstand" to work with L4T. Charges fine, but USB doesn't seem to be working. Anyone know why?

 

[Gavin_Darkglider]

How do you install software? are there repos, or do you have to compile from source?

There are repos..... Mainly the Ubuntu Arm64 repo, which is lacking a lot, and hasnt been updated in quite a while..... Kodi hasnt even been upgraded to 18 yet in those repos. I am in the middle of building gentoo for the switch, which would take things back to being compiled, but at least the stuff that has newer upgrades, can get those upgrades, without breaking ubuntu. lol.

Because non official docks are not supported on L4T. They handle dock negotiations a little different, and the driver doesnt support those docks(yet?) Use the official dock, or get some dmesg dumps, and see what is going on with the bm92t driver. so something along the lines of dmesg | grep bm92, and it will tell you about the negotiation, and what state the chip is in(Dock, usb host, usb device, etc.) There are a few different modes, but I have a feeling it isnt changing like it should, due to the custom stuff that was needed for the switch dock.

It's licensed by Nintendo, so it seems that you are saying that it works with only the one dock.

Hey i've been trying to install anbox, but I cant't find a working arm64 port. It says in the patch notes that it now has the right modules for it right? Can someone maybe help me or link me a working tutorial. I'm not that inapt so a little direction is all I need.

Precisely

The power button, works in linux?, or to sleep I have to give the padlock? because in version 1.3.1 it does not work

I was looking into it, and it seems you need a special built arm64 android root. The best I found was: https://github.com/HarleyPato/anbox-arm64 and even that seems to have issues listed.... But what on github doesnt. lol. I was going to work that out later for my build, but I am having enough issues fighting with the updates, and software install trying to keep both gentoo, and the nvidia drivers happy. lol. Really, it has nothing to do with with the nvidia drivers, but more on gentoo's dependence on perl, which the version they want you to have doesnt work with perl-cross yet, but it doesnt want to continue since it cant build that 1 package, because so much of the base system depends on it. It is a work in progress though. and goes fairly quick, since I told it to build binary packages as well. lol.

Edit: Think I found a fix for the perl issue..... now I go back to waiting. lol.

Oh oke thnx for clarification. Guess I'll just have to wait for news then.

Could not get anbox to work, look at that: https://github.com/anbox/anbox/issues/1043

I cant get it to build because libboost.

 

[Qubarf]

Has anybody tried shashlik yet?
And Bylaws, just asking, are you still thinking about making android work?
It’s my personal opinion but I think android would be much more practical on a switch than Ubuntu.
Thanks!

The linux L4T release has done a lot of the groundwork for Android, they're waiting for nvidia to release updated drivers for a new android release.

The android remote play client can be made to run on non-sony devices, the hardest part is getting the controller working.

Is this true, just want to confirm

My build already has libboost, and the headers installed, so building anbox wont be the issue, but building the special arm64 android root might be. Should be fun, as I havnt tried to build it before. lol.

I am not sure l4t is the answer for android, especially since I have seen no video card drivers for android in any of the bsp releases I have gone through. If there were, I am sure Bylaws would have released Android Switch by now. As I am rebuilding my build again, to see if I managed to fix the build issues I was having, it might be a while until it is ready for that.

Actually, after looking into it a bit more, I found this, which might make l4t a viable android candidate: http://nv-tegra.nvidia.com/gitweb/?...git;a=shortlog;h=refs/heads/rel-30-r2-partner I am not sure if this is the correct version for this kernel, but I would think it would be worth a try. I am not a huge fan of android, so I do not plan on attempting to build android with this, but it would be cool to see working android and linux.

Regular anboz works

It won't work anyway, it will eventually once you get it running think its being ran from /mnt and that messes up stuff, I guess probably some fs namespace issue in kernel.

Nope, nvs source is botched and terrible, it will come whenever its fixed.

 

[pescu]

did anyone got kodi 18 working on switch?

 

[bakedbeans]

I havnt, but I am fairly certain the original failOverfl0w arch build was running gnome3.

Failed to fetch tweet https://twitter.com/fail0verflow/status/964954316892119040 looks like kde, doesn't it?
