By most accounts, the freedesktop.org (fd.o) GitLab instance has been
a roaring success; lots of projects are using it, including Mesa, Linux kernel
graphics drivers, NetworkManager, PipeWire, and many others. In
addition, a great deal of
continuous-integration (CI) testing is being done on a variety of projects
under the fd.o umbrella. That success has come at a price, however. A
recent message from the X.Org Foundation, which merged
with fd.o in 2019, has made it
clear that the current situation is untenable from a financial
perspective. Given its current resources, X.Org cannot continue covering
those costs beyond another few months.
