If OP wants voice and video chat like they say they’d have to host synapse and use element afaik.i don’t think any of the other home servers support matrix calling. Cinny and fluffychat don’t support voice or video calls. Fluffychat has it as an “option” but it’s currently broken last time I tried it. Schildi chat might work for voice and video since it’s an element fork. I’ve not tried it so I don’t know for sure.

IIRC only Synapse supports video/voice calls and only Element & Element X reliably work for video/voice calls.

Gabe has been public about supporting Linux as a gaming platform but I’m not really sure how much he is involved in on the day to day. If you follow what they’re doing Pierre-Loup (PL) seems to be driving most of their Linux work.
