What exactly was the error message? Or do you mean "command not found"
when you tried to run startx?

Could you post your configuration.nix file?

AFAIK, there is no kdm.service. If you enabled KDM in
configuration.nix and did "nixos-rebuild switch" then you should see
that KDM is being run:

$ systemctl status display-manager.service

I'm pretty sure installing KDE with nix-env doesn't work, there are
too many system wide dependencies. It has to be enabled in
configuration.nix.

Try "nix-env -qaP | grep kde" to get a list of packages. The first
column is the attribute name, the second is the package name. You
install stuff with "nix-env -i package-name" or "nix-env -iA
attrname".
