- support for `ecryptfs` in nixpkgs has been removed.
- `services.xserver.cmt` has been removed as the `xf86-input-cmt` package was broken and unmaintained upstream.
- `programs.light` was removed from nixpkgs due to the corresponding package being unmaintained upstream. `brightnessctl` and `programs.acpilight` offer replacements.
- `ceph` has been upgraded to v20. See the [Ceph "tentacle" release notes](https://docs.ceph.com/en/latest/releases/tentacle/#v20-2-0-tentacle) for details and recommended upgrade procedure.

message = ''
cmt and libinput are incompatible, meaning you cannot enable them both.
To use cmt you need to disable libinput with `services.libinput.enable = false`
If you haven't enabled it in configuration.nix, it's enabled by default on a
different xserver module.
