I’m just happy that all the sources are made available by Valve to make this possible. Even though I wish they would upstream them much quicker. But at least it has enabled me to run a normal Linux distribution on my Deck and enhance it as I saw fit.
OpenSUSE Tumbleweed.
Hardest part was getting full disk encryption working with an on-screen keyboard to enter a passphrase at boot. I used unl0kr for that which wasn’t (probably still isn’t) in the OpenSUSE packages.
