1 Before answering comments: well, tonight I've seen there must be
2 something definitely wrong with my XFCE/Composite setup.No more
3 full-time CPU hogging, but switching desktops rapidly became a pain
4 -lags of *seconds* with CPU whirling at nearly 90% in between. I had to
5 kill xcompmgr. Back to plain old vanilla X.

16 It's nice to have learned this. The big big buzz around Xgl led me think
17 quite the contrary, I was aware of AIGLX and that the two projects are
18 planning to merge, but I thought Xgl would have engulfed AIGLX code, not
19 vice-versa.

28 Wow!
29 That's a big step towards what I wanted to hear -integrated 3d desktop
30 without having to hack around with X.I don't like to use ~x86 for
31 critical packages like X, but I hope 7.1 will be x86 relatively soon...
32
33 Time to switch to a nvidia card (maybe for christmas? hmm, I need a
34 laptop too, but a bit more bucks for a nvidia card... mmm, yummy. what
35 relatively cheap (<100 euros) nvidia card would you advice?)

45 Good news.

51 I think so. Hmm. I'm beginning to get interested.

70 I understand, but having each WM to separately rewrite support for 3d is
71 a PITA (for developers, mostly), in my opinion.
72
73 I can't believe no one is thinking to a global solution that every WM
74 can enable. As far as I know, X programming is a wild bad devil, so
75 kudos to the AIGL-X-gl developers nevertheless, but...
76
77 Anyway, when I'll come back to setup a GL desktop, I can switch back to
78 KDE and use Beryl. But having integrated things in KDE 4 would be...
79 mmmmmm... ok, stop the wet dreams NOW.
80
81 (Oh, about wet dreams: for the selective transparency idea, any
82 possibility/news? whom should I ask about it? I feel I like and need it
83 so badly that I can't believe someone with real coding skills isn't
84 thinking about it)
