A sensible NixOS Xfce Configuration

NixOS provides good support for the Xfce desktop environment out-of-the-box, but the defaults are minimal. The files in this Gist provide a more complete experience, including a suite of basic software and plugins as well as an optional home-manager configuration for theming.

The key additions to the default Xfce provided by NixOS are:

• Complete bluetooth / audio support with panel indicators and apps
• LightDM with theme
• Extra Xfce apps for calendaring, disk partitioning, etc.
• Various quality-of-life improving non-essentials

Typo in the package list. Should be

Just wanted to say thanks.
I got my xfce nixos up an running within 30 mins:

ps. for non-homemanager folks (like me), here's how to support the standard .xinitrc way to initialize stuff during X-server boot:

services.xserver.displayManager.sessionCommands = ''
  test -f ~/.xinitrc && . ~/.xinitrc
'';

For example, I use this ~/.xinitrc on one of my systems, to initialize multiple monitors and set the bg-pictures:

# use `arandr` to export the default.sh file (menu: Layout > Save-as)
test -f ~/.screenlayout/default.sh && . ~/.screenlayout/default.sh
xfconf-query -c xfce4-desktop -l | grep last-image | while read path; do xfconf-query -c xfce4-desktop -p $path -s ~/Pictures/wallpaper.jpg;

You are welcome. Thanks for adding the non-Home Manager setup.

Quick note on the video: you can just do the normal GNOME or KDE GUI easy install and then edit your configuration from there. You install Nix, change config, nixos rebuild-switch see if you like it, and repeat iteratively. The old stuff will get removed. The hardware file is generated automatically for your machine, you should leave it alone. Have fun with NixOS!

Thank you for making this available. It'll help me setup my wife's computer in no time!

One thing I noticed. Is sound.mediaKeys.enable = true; needed as the doc mentions that XFCE enables this by default.

You want to leave this disabled if you run a desktop environment like KDE, Gnome, Xfce, etc, as those handle such things

Also, pulseaudio is not enabled by default so this can probably be left out too but I guess it won't do any harm.
