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.

Thanks

Sorry, my web browser froze up. I didn't realise it didn't complete my post. Theoretical methods of Nintendo could use are largely invasion of privacy issues, and unreliable.

I use kodi for that, it does alright.

Do you use the addon Inside kodi?

Just compared. L4T boots for me up in 30sec until a usable grapical screen, and in that state 814MB are consumed:

chris@switch:~$ free -m
              total        used        free      shared  buff/cache   available
Mem:           3483         841        2213          11         429        2372
Swap:             0           0           0
chris@switch:~$

My Fedora30 build with LXDE takes 43sec to load, and after that 512MB are consumed:

[root@switch ~]# free -m
              total        used        free      shared  buff/cache   available
Mem:           3483         512        2270           6         701        2692
Swap:             0           0           0
[root@switch ~]#

My build is not nicely available as image though, one has to follow bootstrap instructions. Also some 3D for example supertuxkart does not start, L4T is probably more compatible. This shows though the potential, is someone is after 300MB, then playing with smaller window managers on L4T might make sense.

If supertuxkart doesnt work, your GL stack is wrong. Lakka did it wrong as well, since they stubbed out mesa and used symbolic links over the mesa files, when in reality, it needs GLVND, and a version of mesa that supports it. Once you get that set up properly, you will have working supertuxkart, at least with gles. GL does work the way lakka set it up, but it is still wrong.

Do you use the addon Inside kodi?

yes.

Congrats on getting sleep mode working! I'm going to try this today.

Can you boot into hekate or any other payload from L4t?

No, not so far.

 

[Gavin_Darkglider]

Work on L4t Gentoo has stalled because of my work schedule, and time constraints. I am looking to start collaborating with @bell07 who is looking to achieve the same goal, and has server space to host a proper repository, which is one of the main reasons why I havnt released what I have, as portage will break things the moment you update the tree right now. I cant fix that without a real repository, which I have no where to host.

I just used Etcher to write the image, but on OSX I don't see any partitions I can mount. Just the two Linux ones. Any idea? Shouldn't there be a FAT partition for payload? Am I supposed to be doing this in Linux? I have a laptop with Ubuntu somewhere.

Yes, for installing the updates you should mount the first of the 2 partitions.
If installing the updates causes you much pain, you might want to try to get the system up in the initial state without updates, and later from the running L4T install the updates - it can access both partitions.
Not sure if MacOS is supposed to see and access the partitions, but an Ubuntu should definitely. There might also be usb- or dvd images where you can boot the Mac directly without installation, and then access the partition.

Congratulations, it seams Langer Hans from Switch root has managed to successfully lp0! This a major step a working deep sleep for both linux and the up-coming android!!!

Thank you. I have another question... So is the Linux launcher in the Hekate payload? Because usually you have to put a .ini in a folder in the root of the SD card for it to read them. Like Kosmos for instance.

 

[Gavin_Darkglider]

the ini is included in the image.

Got it running. Thanks!

Which is the 2nd partition in my microsd card? One that says "Filesystem Partition 2 8.1 GB free?"

I would assume so, if you flashed the l4t image.

 

[gbazone]

Feeling quite foolish again. I have my SD card plugged in to my Laptop running Ubuntu, but I cannot drag the updates to it because I don't have permission. Should I do it straight from the Switch instead?

FAT32 doesnt have permissions, but the ext4 partition does. Easiest way would be to open a terminal and type sudo nautilus which will open a file manager as root, which will have the permissions to edit all files on the sdcard.

 

[BruhBoy]

Any way to turn off sleep mode

I always apply the updates straight from L4T Ubuntu on the Switch.

 

[NANASHI89]

I would assume so, if you flashed the l4t image.

So, how do I remove said partition, so I can get complete access to the whole memory card?
