# X.org {#sec-xorg}

The Nix expressions for the X.org packages reside in `pkgs/servers/x11/xorg/default.nix`. This file is automatically generated from lists of tarballs in an X.org release. As such, it should not be modified directly; rather, you should modify the lists, the generator script, or the file `pkgs/servers/x11/xorg/overrides.nix`, in which you can override or add to the derivations produced by the generator.

## Katamari Tarballs {#katamari-tarballs}

X.org upstream releases used to include [katamari](https://en.wiktionary.org/wiki/%E3%81%8B%E3%81%9F%E3%81%BE%E3%82%8A) releases, which included a holistic recommended version for each tarball, up until 7.7. To create a list of tarballs in a katamari release:

```ShellSession

export release="X11R7.7"

export url="mirror://xorg/$release/src/everything/"

cat $(PRINT_PATH=1 nix-prefetch-url $url | tail -n 1) \

  | perl -e 'while (<>) { if (/(href|HREF)="([^"]*.bz2)"/) { print "$ENV{'url'}$2\n"; }; }' \

  | sort > "tarballs-$release.list"

```

## Individual Tarballs {#individual-tarballs}

The upstream release process for [X11R7.8](https://x.org/wiki/Releases/7.8/) does not include a planned katamari. Instead, each component of X.org is released as its own tarball. We maintain `pkgs/servers/x11/xorg/tarballs.list` as a list of tarballs for each individual package. This list includes X.org core libraries and protocol descriptions, extra newer X11 interface libraries, like `xorg.libxcb`, and classic utilities which are largely unused but still available if needed, like `xorg.imake`.

## Generating Nix Expressions {#generating-nix-expressions}

The generator is invoked as follows:

```ShellSession

cd pkgs/servers/x11/xorg

<tarballs.list perl ./generate-expr-from-tarballs.pl

```

For each of the tarballs in the `.list` files, the script downloads it, unpacks it, and searches its `configure.ac` and `*.pc.in` files for dependencies. This information is used to generate `default.nix`. The generator caches downloaded tarballs between runs. Pay close attention to the `NOT FOUND: $NAME` messages at the end of the run, since they may indicate missing dependencies. (Some might be optional dependencies, however.)

## Overriding the Generator {#overriding-the-generator}

If the expression for a package requires derivation attributes that the generator cannot figure out automatically (say, `patches` or a `postInstall` hook), you should modify `pkgs/servers/x11/xorg/overrides.nix`.

- `iroh` has been removed and split up into `iroh-dns-server` and `iroh-relay`.

- the `xorg` package set has been deprecated and will be removed, packages have moved to the top level.

- `python3Packages.pygame` has been been renamed to `python3Packages.pygame-original`, the attribute `python3Packages.pygame` will from python 3.14 default to the more actively maintained `python3Packages.pygame-ce`

- `python3Packages.gradio` has been updated to version 6. See upstream's migration guide at https://www.gradio.app/main/guides/gradio-6-migration-guide.
