This is the master branch of nixpkgs, initially pulled from commit 8debf2f9a63d54ae4f28994290437ba54c681c7b The intent of this repo is to be merged onto nixpkgs master. This will also be of help for https://git.suyu.dev/BoomMicrophone/suyu-nix-test which I will need in order for development (it will also be helpful to know what to do for setting up the environment for the master server. Currently I am focusing on this so I can actually see what is still missing) This repo will be removed once the PR to the nixpkgs github goes through

8573 34435a9502 redshift: Fix default value of $DISPLAY (#17746) 
Before commit 54fa0cfe4e, the `redshift`
service was run with the environment variable `DISPLAY` set to `:0`.

Commit 54fa0cfe4e changed this to
instead use the value of the `services.xserver.display` configuration
option in the value of the `DISPLAY` variable. In so doing, no default
value was provided for the case where `services.xserver.display` is
`null`.

While the default value of `services.xserver.display` is `0`, use of
which by the `redshift` module would result in `DISPLAY` again being
set to `:0`, `services.xserver.display` may also be `null`, to which
value it is set by, e.g., the `lightdm` module.

In the case that `services.xserver.display` is `null`, with the change
made in commit 54fa0cfe4e, the `DISPLAY`
variable in the environment of the `redshift` service would be set to
`:` (a single colon), which, according to my personal experience,
would result in —

  - the `redshift` service failing to start; and

  - systemd repeatedly attempting to restart the `redshift` service,
    looping indefinitely, while the hapless `redshift` spews error
    messages into the journal.

It can be observed that the malformed value of `DISPLAY` is likely at
fault for this issue by executing the following commands in an
ordinary shell, with a suitable `redshift` executable, and the X11
display not already tinted:

  - `redshift -O 2500` — This command should reduce the color
    temperature of the display (making it more reddish).

  - `DISPLAY=':' redshift -O 6500` — This command should raise the
    color temperature back up, were it not for the `DISPLAY`
    environment variable being set to `:` for it, which should cause
    it to, instead, fail with several error messages.

This commit attempts to fix this issue by having the `DISPLAY`
environment variable for the `redshift` service default to its old
value of `:0` in the case that `services.xserver.display` is `null`.

I have tested this solution on NixOS, albeit without the benefit of a
system with multiple displays.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:

% git remote add channels git://github.com/NixOS/nixpkgs-channels.git

For stability and maximum binary package support, it is recommended to maintain custom changes on top of one of the channels, e.g. nixos-16.03 for the latest release and nixos-unstable for the latest successful build of master:

% git remote update channels
% git rebase channels/nixos-16.03

For pull-requests, please rebase onto nixpkgs master.

NixOS linux distribution source code is located inside nixos/ folder.
