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.
Ok, so what did xlibre achieve then? Is multi-monitor with mixed refreshrates + vrr a thing yet?
As far as I’m aware, that was already a thing somewhat with XOrg. It may have been in alpha state, but it was something. Wayland is more broken with it from what I’ve read on the issue.
