Olivier Fourdan's 2021-03-26 X.Org development RFC explained that the CVT modeline generator existed inside the Xorg server, was also used by the cvt utility, and had been copied into Xwayland; the proposed library removed that duplication and made the generator available as a standalone project. The first release announcement, libxcvt 0.1.0 in July 2021, described it as the VESA CVT standard timing modelines generator extracted from the Xserver. Later X.Org announcements describe both the library and a standalone cvt tool copied from the Xorg implementation as a direct replacement for the version formerly provided by the Xorg server. ### Adoption history libxcvt's adoption is tied to the modularization of X.Org and Xwayland. By moving cvt generation outside the server tree, display stacks and packages that needed modeline generation could depend on a small library/tool package rather than carrying or installing more of Xorg server. ### How it is used Users call cvt to calculate modelines for a requested resolution and refresh rate, while system components can link the library to generate the same timings programmatically. It is a narrow package, but it sits in the practical path for custom monitor modes and X11/Xwayland build-time needs. ### Why package nerds care libxcvt is interesting because it is a clean extraction package: a small piece of historically server-owned X.Org code moved into a library so packagers could stop dragging around a bigger component for one timing algorithm. ### Timeline - 2021-03-26: X.Org development RFC proposed moving the standalone libxcvt project into the xorg/lib namespace. - 2021-07: libxcvt 0.1.0 announced as the first release extracted from Xserver. - 2022-07: libxcvt 0.1.2 announced on X.Org mailing lists. - 2024-12-14: libxcvt 0.1.3 announced with fixes and CI/static-analysis updates. ### Related projects - Related projects include Xorg server, Xwayland, xrandr, Mutter, and the wider X.Org modular library set. ### Sources -
