If someone wants to file a FESCo ticket to get it approved as a late change, I think that's reasonable. But tomorrow is go/no-go and I think it's at least as risky to flip back to Xorg by default as it is to leave Wayland the default; and no doubt FESCo would take QA's opinion on the late change into account but this lateness I think is pretty minor compared to some of the late changes that have happened in the past. I think a case can be made that it was always intended to be the default for Fedora 25, it very nearly was the default for Fedora 24. It's something of an oversight there was no change filed for Fedora 25, and it just slipped through the crack. Unless testers are manually changing to Xorg, it is being tested since it's the enabled default, which is a requirement by the change process. It probably also is at or nearly at the 100% code complete point well before that deadline; and if it's not 100% then the WG can estimate how far away it is and how likely it'd be at 100% by that deadline. Top on my list of blocking behaviors for which I'm not aware of an appropriate release criterion is: by beta the switching between wayland and X needs to be bulletproof; in particular the ability to switch from Wayland to X must actually work and must stick through a reboot (persistence). As long as the user can reliably use X, I think the worst of Waylands maturation problems are surmountable. There is an in place fallback, it's not like pretty much all other system wide complex changes where there is no such user initiated fallback available. -- Chris Murphy -- desktop mailing list desktop@xxxxxxxxxxxxxxxxxxxxxxx https://lists.fedoraproject.org/admin/lists/desktop@xxxxxxxxxxxxxxxxxxxxxxx
