Yet despite having complete control we did not manage to come up with a truly good workspace experience that starts at the DM (power management, good looks, I for one have yet to see a sane UI-wise integration of stuff like fingerprint auth, integration with the workspace like say MS Windows displaying unread mails etc.). So, yes, giving away control is certainly a dangerous thing, and needs to be well throught through and evaluated (if it should happen at all that is). Not just in terms of control but also in terms of feature parity. It certainly would hurt the image of the KDE workspace to switch from a capable, proven, well tested and mature DM to one that does not even measure in terms of features. Let alone reliability. With that in mind it certainly would be a good idea if everyone who threw up rants and whatnot to actually take a look at the status quo and see if lightdm is a viable alternative for antyhing, and if not how to make KDM provide the experience that we need to keep up with our competition. Perhaps we should actually first find out what we need? Regarding the control issue with regards to workspace integration though... Maybe I misunderstood the architecture of LightDM, but to me it seems that all workspace affecting parts would be in the greeter rather than the base of the DM (I figure that is what we have right now in KDM too). What would be "outsourced", if you will, is the actual logic of the DM, which for the better part has little to do with the workspace experience. We would still be in control of all the UI parts, and the DM logic part is certainly not where most of the valuable UI plunder should go (that also includes fancyness enabling technologies such as Plasma). Sure, regarding the actual display management we would be at the mercy of LightDM and its developers, but from a workspace point of view I reckon there is not all that much to be done in the DM logic. > > At any > > rate it probably does not make sense to take such things into account > > for any technical discussion as long as the system in use is easily > > accessible.

So yes, sounds very much like an > issue to me. I am not the biggest fan of bazaar either, but I think saying it is only used by one distribution is a bit unfair. Also important projects such as MySQL, Inkscape, Zeitgeist and various GNU projects such as Emacs and Grub use it. I would be very surprised if bazaar packages were not available in every serious distribution. Also unlike git it is not a PITA to use on Windows :P Anyhow, I do not think this is a topic worth discussing just now. Seeing as we did not even identify LightDM as anything we need or want to use in place of own technology. To me the selection of VCS or development infrastructure at large is at best a political issue. I'll ask Robert though. regards, Harald
