CachyOS Multiseat?

I bough today AMD GPU and new PSU to support new GPU and my old NVIDIA -both.

My tough is to setup multi seat as per on this video just to be able use my desktop while second one is reserved for gaming or both.

Any initial toughs about this as bad idea for reason x,y,z or maybe it actually is doable?

I admit, I know, multi seat is kinda forgotten technology but to be honest: I really do not understand why, specially with Linux environment.

Multiseat is not forgotten, just not many people need it. Do you share your pc with someone?

Not yet but plan is dedicate second session for tv gaming and rally sim while second one will be ‘regular desktop / gaming’
