NixOS list all possible configuration options

Question

I started using NixOS a few days ago. It seems like there is a configuration option for everything, e.g. hardware.opengl.driSupport32Bit or system.copySystemConfiguration.

But the question is: can I see all options which are available? To give a few examples:

• How should I know what desktopManagers are available other than the "kde4", "kde5" and "gnome3"?
• What synaptics options can I use, other than accelFactor and twoFingerScroll?

Answer 1

You can search them at http://nixos.org/nixos/options.html or get the whole list at http://nixos.org/nixos/manual/options.html.

It's also possible to get the list at man configuration.nix
