Linux

Hi, everyone!

A few months ago I have purchased a used Jetson Nano 4G (not to be confused with the newer Orin model) for pennies and ever since have tried to the best of my ability to make it useful, i.e. not e-waste.
This machine runs Ubuntu 18.04 on Arm and Tegra. It can be upgraded to newer releases (forcefully), but seems useless outside AI vision stuff as it lacks any meaningful software support.
No HW acceleration in the browser or video playback (outside of barebones gstreamer). Ubuntu seems rather buggy with anything but Gnome and some audio related stuff just keeps breaking every few minutes.
There are some community guides on the official forum and some outside of it, but in general, you have to stick to 18.04 to get the bare minimum working and even then, the outdated browser makes most of the internet unusable.
I've tried to contact people who claimed to have made HW acceleration work in general, but no one responded and most links are dead because they are 3-4 years old.

Can anyone here point me towards some if ANY resources to make this little machine useful? I've read every single post on the forum, on jetsonhacks (mostly regurgatates other resources) and on github (Ubuntu 20.04 images fail for me).
