11 Quite the other way around, as far as I've been able to tell. Xgl got
12 greater publicity, yes, but AIGLX is the one that will eventually be the
13 "official" solution - it's already present in Portage's xorg-server in
14 some form.
15
16 By the way, the latest beta drivers from nVidia provide the OpenGL
17 extension that Compiz and Beryl use, so you don't even need AIGLX nor
18 Xgl, and DRI can remain enabled (wobbly quake3! ^_^). My laptop at the
19 moment has no overlays at all - xorg-server from ~x86, compiz from ~x86,
20 and nvidia-drivers in package.unmask - and it's all working very nicely.
21 :) Hopefully other driver devs will follow suit.

30 Yes. I tried compiz+AIGLX on my old Celeron 1.5GHz with integrated
31 motherboard video (eeew!) just for kicks and it ran fairly smoothly -
32 modest framerate, but definitely usable. If you mean literally fast,
33 then also yes - all of the animations happen within half a second or so
34 (not that I've measured ;)). There's a key shortcut, too, if you want
35 to see jiggly windows in slow-mo. (shift-f10 is the default, I believe?
36 Someone help me out on that one.)

43 That is awfully cute. :) My favorite feature is the window scaler. Oh,
44 and the way the rest of the desktop sort of drops into the background
45 while Alt-Tabbing - it's subtle but cool.

56 It depends on how important the WM is to the whole thing, you see.
57 Compiz and its fork, Beryl, work very well with Gnome and KDE because
58 the window manager isn't very important to them - it does very little
59 besides manage windows, while (in Gnome for example) gnome-session and
60 Nautilus do a lot of work as well. There's even a separate program that
61 handles window decorations (gnome-window-decorator in Gnome, kwin I
62 think in KDE). On the other hand, with Fluxbox, Openbox, and similar,
63 the WM is all there is, so it's a big deal to change it. You can't have
64 "Compiz integration in Fluxbox", since they both do the same thing, and
65 will refuse to run at the same time. I have, however, heard rumours of
66 an Openbox clone with some Compiz code spliced into it in initial
67 development... :D
