[Nix-dev] setting kdm?

[Sander van der Burg - EWI]

Well, I know this sounds confusing because the kdm upstart service is basically a hack and not coded properly. The reason why you should disable the xserver is that the xserver upstart job will start the slim display manager and we want to use KDM as display manager, not slim.

The only reason why there are xserver properties in the configuration.nix is that I wanted to use the same xserver properties as the regular xserver upstart job, instead of duplicating them in system/options.nix. The kdm upstart service is just a temporary service anyway.

I know this is dirty. Preferably, we just want one xserver upstart job that you can use to start either slim, kdm, or some other display manager such as gdm. When I'm done with experimenting with kdm, I will merge it with the regular xserver upstart job.

Thanks for the info Sander,
I follow but not completely.
I can see that with kdm set like that in configuration.nix means that
xserver needs to be enabled = false because kdm is a clone of that but
do the xserver settings whilst this clone of the xserver config is
being used need to be in the kdm section?
What I mean is, If the settings are in the xserver section, Will they
still be used if I do set kdm = true?
So do I need to replicate them into the kdm section?

Sorry if it's silly question but I haven't explored the upstart jobs
yet, NixOS is still pretty new to me and I'm used to the old way of
managing services that Mandriva Linux still uses.

Thanks again,

Tony
