Could pipewire be used to work around lack of acceleration in Xinerama?
Not really an issue, but I didn't see an official forum in the site, so here I am. I happen to use two GPUs from different vendors to drive 3 monitors, Matrox and Nvidia, but my understanding is it would be the same if it were AMD+Nvidia, or even same vendor from disparate generations. On such setups, Xinerama seems to be still the only way to get Extended Desktop functionality.
The X server's own Xinerama has no acceleration of any sort, though it is poorly documented.
Would it be possible to use Pipewire to aggregate separate X screens onto a single desktop or some clever thing like that?
