Sam Bent, 8 months ago (at this time), covered XLibre, which is essentially a fork of XOrg that wants to clean up the codebase, modernize it, and fix the security holes that lasted for years on XOrg.
Meetux, the developer, became persona-non-Grata in FreeDesktop, IBM, RedHat, and possible GNOME circles, simply because he wanted to fix Xorg so people have an option on what they want to use.
It’s also why I won’t kowtow to IBM, GNOME, and FDO’s demands, due to technical merit being moot.
I’ve had a wonderful time with XLibre, actually. Granted, Picom is broken (it always was, to be fair about it), though I figured that out real quick.
Daaaamn, good thing that the main selling point was “everything you used before works the same”. I guess it does not have feature parity with xorg, huh?
