KDE and LightDM revisited

LightDM is a login manager (think KDM/GDM) for Linux, it is written in a way that is completely backend/frontend independent so we can share our the complex parts with our Gnome friends, whilst keeping KDE UI layers on top. It is currently the default display manager in Ubuntu...

I played with it - very nice, but not as featured as kdm yet. Definietly got potential.

Here's an interesting counterpoint that raises some arguments against a non DE-specific display manager...

Here's an interesting counterpoint that raises some arguments against a non DE-specific display manager...

The first comments to that article basically say that power management should be independent of the DE. I agree 100% with this. I have never understood why power management (including disk spin down, screen dimming, screen sleep, system suspend, system hibernate, and probably more) should require a specific DE. ... Well OK, I do: because originally no one ever thought these things were important for desktops and still they probably aren't important for servers. I'd like my power management (and a few other things* but I can't recall my list now) to be functional before I start X and to be the same regardless of which DE I launch, if any.

Oh yes, remembered one - my password safe - especially for wifi so that I can access my wireless network when I boot to a command line!

All the DE should have is GUI tools to configure the power management settings and the password safe and those other things I can't remember, but they should all be implemented outside of X. ... Which I suppose means even lightdm is the wrong place for power management.

But something tells me this will never happen ...

[SteveRiley]

Agreed. Neither the DE nor the DM should be responsible for such basic functionality as power management, network management, time zone configuration, and so on. Matter of fact, I believe that there exist sufficient command-line utilities for managing all these. The DE should simply provide a GUI overlay for existing utilities.

Wait...I think I just wrote the same thing you did...!

[SecretCode]

Do sufficient command-line utilities (daemons as well as settings utilities) really exist? Networking yes, but power management?

And more importantly, can our favourites DE(s) be configured to use the command-line platform's utilities instead of enforcing their own?

[SteveRiley]

The repos show a few utilities that have some kind of power-management function:

* laptop-mode-tools
* pm-utils
* powernap
* acpi-support
* powertop

The LessWatts.org project has more.

I suspect these reflect various states of maintenance; I haven't thoroughly investigated them. Regarding how/whether KDE integrates with them, I don't have an answer for that.
