AW: New libxcvt library

[Walter Harms]

Hi,
i think it is a good idea.
Can you give a hint how big that lib is ?

Even when the idea is good it is not really helpful to have to many
different libs hanging around. I read Keith Packard was already considering putting that into xrandr, if its not to big i would say it would
be a good idea to collect the monitor related things into one lib (EDID ?).

Hi all,

Currently. the Xorg Xserver has its own implementation of the VESA CVT standard timing modelines generator in `hw/xfree86/modes/xf86cvt.c`.

That code is placed in its own source file alone because it is also being used by the `cvt` utility.

Because it's part of the Xorg DDX, Xwayland, which is another DDX also has a copy of the same code in `hw/xwayland/xwayland-cvt.c`.

Now with Xwayland being a standalone package, mutter which uses the cvt utility at build time still needs to install `cvt` from Xorg to generate the modes used in Wayland.

Some time ago, discussing with Jonas Adahl on irc, we thought it would be a good idea to have that code and utility part of its own standalone project, to avoid the code duplication and possibly ease contributions.

That was https://gitlab.freedesktop.org/xorg/xserver/-/issues/1142

So I went ahead and did just that, called it “libxcvt” and placed in https://gitlab.freedesktop.org/ofourdan/libxcvt

I also made a merge request to use that code in the Xserver: https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/637

Can we consider moving “libxcvt” to the xorg/lib namespace in gitlab?

Cheers
Olivier
