Ah, that's because of Compiz. When I first found out that KDE devs are implementing 3D desktop effects into KWin window manager, I asked why are they reinventing the wheel, since Compiz is way more developed in this respect. Their answer was --- Compiz doesn't work without 3D acceleration while KWin does, and KWin is overall better integrated in the new KDE than Compiz. So they figured it is less work to reimplement all of (ie. most of) 3D desktop effects in KWin, than to implement 2D fallback functionality in Compiz. It's an ugly tradeoff, but I generally understand and agree with their decision. Of course, one can always ignore KWin and run Compiz on top of KDE, without any problems, if one has proper graphics hardware for that. I do that since F9, and with every new Fedora version I check out the current capabilities of KWin desktop effects and whether they're good enough to switch from Compiz to KWin. So far they're not there yet, so I keep using Compiz. The Gnome devs apparently decided to take the opposite route in the above tradeoff situation. Whether or not it is uglier than what KDE folks are doing, I don't want to judge, time will tell. ;-) Compiz is designed with a built-in assumption of availability of 3D acceleration, and it would be extremly hard to make it work without it. So I guess Gnome devs are using Compiz when 3D is available, and fallback to the old WM (is it Metacity?) when it isn't available. So in a way they have to maintain two window managers simultaneously, which was exactly the situation KDE devs decided to avoid. Such type of decisions depend highly on the development model, available manpower, details of the relevant API's, etc. Maybe both Gnome and KDE devs made correct decisions, each for their own environment. I'm curious to see how will it pan out in the long run. :-) :-) Marko -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
