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.

When upgrading your ubuntu img using 'sudo apt upgrade', everything seems to upgrade normally except for this last part:

update-initramfs: Generating /boot/initrd.img-4.9.109+

Is that normal or expected ?

I'm unsure of the best settings for the Dolphin emulator and how to use the Joycons as controllers for the emulator. Ive got games booting but it seems they're abit laggy aswell..
Would someone be able to give me a hand?

When connecting a screen using a HDMI to DVI cable the image is pixelated and fuzzy. 5cm in the left part of the screen are OK, the rest is fuzzy and pixelated.
When docking the switch running Horizon OS, the display is fine.
I tried to deactivate HDMI sound (in case it would be mixed up with the image signal... no sound through DVI anyway) but I did not manage yet. (I guess it is not possible to blacklist the module responsible for hdmi sound as it is not separated from the kernel ?)
Changing the display mode using xrandr does not solve the problem.
Any idea ?

 

[Evandro_VV]

Expected
yes

But i can't seem to get it working, do i have to run something in the terminal?

 

[DerEineee]

Could someone please try a DS emulator?
I could imagine that it would run pretty good especially in combination with the ability to really use the touchscreen

 

[vitxo]

Is it possible in the future that ubuntu can reboot to hekate?
like reboot to payload of atmosphere

Melee - consistent 60 fps

Double dash - consistent 60 fps.

I'm trying tons of games tonight, got any requests?

Can you try Baldurs Gate Dark Alliance ? If it isn't too much hassle.

Try a few modes, maybe one will work

Give dmesg when plugging in

Tried them all, some worst than the other, some better, not one that is really working.

i followed a video on youtube to install this, and it all went fine until i try to run the payload. then i just get a black screen

 

[cirojr82]

Well, nice job indeed.

I managed to sync the joy cons, but I can't move the pointer using the analogs as a mouse.

Does it just works for games?!

Thanks

Usually restarting the switch after installing the joy cons will all you to use them. Just re sync them through Bluetooth then press L +R on both joy cons and they should be operable

 

[stick267]

Using the joycons as a mouse is not out of the box behavior. You have to install a separate utility. I use Qjoypad.

Do

sudo apt-get install xserver-xorg-input-joystick

Then reboot and re sync the joycons
