Wayland does not support screen savers: it does not have any provision that allows screen savers to even exist in any meaningful way. If you value screen savers, that’s kind of a problem.
Adding screen savers to Wayland is not simply a matter of “port the XScreenSaver daemon”, because under the Wayland model, screen blanking and locking should not be a third-party user-space app; much of the logic must be embedded into the display manager itself. This is a good thing! It is a better model than what we have under X11.
But that means that accomplishing that task means not just writing code, but engaging with whatever passes for a standards body or design committee in the Wayland world, and that is… how shall I put this… not something that I personally feel highly motivated to do.
Did he say that because the answer to IF it worked was no?
He was referring to proprietary BIOSes that work for sure but suck. Coreboot on the other hand also works but doesnt suck
