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.

Link above updated to fix issues in original image file. If you downloaded that, and it didnt boot, redownload and flash again, and everything should work.

thank you so much for the update, is it possible to use keyboard and mouse that are wireless whilst on portable mode? thanks once again!

 

[Gavin_Darkglider]

Via bluetooth sure, otg still doesnt work.

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

Op updated with the latest image, and updates removed. Sorry, but if you want this update, you will need to start over with your sdcard.

 

[Moe90]

is there by any chance for an alternate download link for the latest ubuntu image, cuz mega keeps telling me the quota exceeded and am gonna have to wait for 5 hours to continue my download, thanks for any help!

 

[Gavin_Darkglider]

no, I only uploaded it there. Last time I put something like that on dropbox, dropbox threatened to shut me down after 20 minutes, because I wasnt paying them commercial rates. Something about exceding 2 months worth of downloads in less than 24hours. lol.

[mrcroket]

I tested the new build and works great,the only downside is that moonlight (embedded) still not working with hardware rendering, h264 its choppy and h265 glitched and also choppy

 

[Gavin_Darkglider]

And it doesnt matter what kernel we use, until moonlight itself supports tegra nvdecoder in linux, it will never work right.

Great work. Finally touch screen works as expected!
I see that boot partition is still not visible under macOS.
I just deleted it via gparted, created new partition, formatted to FAT32 and market as lba.
It become visible on macOS and it boots fine. Also it is visible under Windows.
Why you haven't fix it in a released images?
And why ~450 mb packages of the libreoffice+thunderbird is preinstalled, do anyone really need it?

the 450+mb of packages was installed in the old image. this image is the old image with all of the new stuff injected into it. I didnt even update the software, so it is still as outdated as the original release. I was planning on updating it all to the latest l4t root upstream at some point, but it is still 18.04, so

apt update && apt upgrade

should get you to the upstream stuff. currently I am looking at possible options to bring back hardware decoding for things like moonlight, and kodi.

Did I see that sleep mode works? Am I reading this right!?

Yup :shrek:
And it’s the good sleep. It uses around 10% per day iirc (it’s been awhile since I’ve tested ), which isn’t quite as good as HOS, but it’s still pretty good.
It does have one issue though, sometimes the touchscreen won’t work after waking (also can happen after undocking) on certain systems.

You can add an option to disable and re-enable touchscreen on/off dock which should fix the issue for docking
you just have to add 2 xset lines to /usr/bin/dock-hotplug
