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.
Features
Dock support with USB
Bluetooth (both controllers and audio)
Nvidia GPU drivers - Vulkan and OpenGl
Audio - Headphones, speakers and over HDMI when docked.
Joycons and pro controllers are supported fully when not attached to the the console
Touchscreen
Display
WiFi
CPU frequency scaling - The CPU scales from 200mhz to 1.7ghz (what switch is binned for) depending on the load its under. Fans are adjusted to account for this
Full sdcard speed
Hardware video acceleration when using the built in videos app (means you can watch videos without battery draining massively)
Prerequisites
A dedicated 16GB+ sdcard

Downloads: Sdcard image: https://download.switchroot.org/switchroot-l4t-ubuntu-2019-04-28.img.gz
How to install
Download the image from the downloads section and extract.
Write it to your sdcard using a program such as etcher or dd.
Boot hekate and select L4T from the configs menu.
Wait for around 2-4 minutes while it initially loads
Go through the setup process - make sure not to dock the console in this period.
Once the initial setup is finished and you are on the login screen it is advisable to reboot:
Hold the power button for 10 seconds.
Load hekate again and select L4T as a payload.
Log in and open the "Disks" app
Select the second partition of your sdcard and click the gears icon
Choose resize and change the size to the full amount of available space.
Enjoy, you now have fully featured Ubuntu on your switch!
Bugs
Wired joycons do not work (connected to console)
Docking while having a ssh session open can cause the display to not turn off correctly
No sleep mode
USB OTG - works fine in dock though
Vulkan is buggy in dolphin
Misc Info
Pair (joy/pro)cons by opening the bluetooth menu in settings and pressing the + button in the bottom left corner. Then press the sync button on the controller and select its name in the pairing window. Once both joycons are paired press each of their shoulder buttons to use as one controller
To use dolphin add the "dolphin-emu/ppa" ppa and install the dolphin-emu-master package.
To update the system run "sudo apt update", "sudo apt upgrade". This will apply all switch and ubuntu updates aside from kernel updates, they will be posted here if ever needed.
To limit cpu freq, run cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies.Ffind the one you want, then run: echo <freq you want> | sudo tee /sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq
To force max freq run echo performance | sudo tee /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
A gui to configure overclocks and fan profiles is coming soon, along with support for using 2.0 ghz cpu
