Is a tablet that doubles as a USB-C second laptop display a (FOSS) thing? (lemmy.world)

Really only interested in something like Graphene, Lineage, or a Linux mobile tablet that can work with a typical Linux distro and display over USB-C. It is just a casual conversational ask. Maybe one of y'all has tried or knows the answer. I won't use anything that runs google stuff or is a pain to load a custom ROM.

The utility of having both would be enough for me to consider purchasing a tablet when I will not otherwise. It should only be a small amount of code in AOSP to work with any device. I am also half ass shining a spotlight on the ridiculousness of this not existing by default on all devices. There are even protocols for display over micro USB. At the very least this should be a F-Droid FOSS app. All devices should go as far as having this potential functionality like an EOL where the modem can be disconnected along with all other apps and only run the device as a video pass through so that no code vulnerabilities from abandoned orphaned kernels can run exposed to external sources. Then the user could safely select to continue using any Android device as a display.

Man, 100% agreed. Devs didn't think about EOL at the time, but hopefully someone will implement this at some point because environmentalism has been growing bigger than ever.

Surprisingly, even for interactive screen-mirroring, there is still generally only scrcpy—which is even used by giants like SideQuest for Meta Quest VR headsets (since they're Droids). Previously there was Vysor.io, but that's closed-source and for-profit.

Anyway, this totally reminded me that I once really tried to look into this but found that the only solution in the entire known English-speaking world for this is currently the closed-source, freemium Spacedesk + a rooted tablet. I gave up because at the time I didn't wanna try to root the tablet due to the mandatory factory reset, but I eventually caved in to install Kotatsu lol. Haven't retried...
