[Nix-dev] synaptics touchpad problem in trunk

[Lluís Batlle]

I use synaptics, and it worked for me.
Some time ago nixos pointed to the wrong synaptics package... I don't
remember if I commited my change for that. Are you sure you use trunk
of nixos?
It was that nixos still wanted the pkgs.synaptics, while there should
be pkgs.xorg.synaptics, or something like tihs.
pkgs.synaptics didn't follow the xorg update, afaik.

Regards,
Lluís.
