Just an observation, on two machines which were perfectly usable with
FC8, after "upgrade" they are really nasty to use in terms of video.
Moving a windows leaves a comet trail of window outlines which take
1-2 seconds to clear, minimizing a window results in a trail of
shrinking outlines, the minimize takes seconds and a few seconds after
that for the outlines to fade.

This feels like vista, in the names of cool features the video has
been made painfully slow. All under GNOME, I expect issues with the
new KDE, but if this is the "improved" X, the code or the default
configuration is aimed at either gamers with $500 video cards or
people who like eye candy and effects so much they want time to
appreciate them.

I'm having similar issues with video in F9. I have an onboard intel
chip that normally uses the i810 driver. I figured it's probably not
using acceleration and glxinfo showed DRI = no at one point, now when I
run glxinfo X crashes alltogether. However if I boot off the Live cd
everything is perfect. That's the weird thing. With the live cd there
is no /etc/X11/xorg.conf meaning that X uses builtin configuration for
my video chip and that works very well. I don't understand why the
full- fledged F9 doesn't do the same.

Also, if I boot in runlevel 5, sound works. In runlevel 3 it doesn't.
Yeah, and there's no sound configuration tool anymore.

I'm downloading CentOS as we speak.

I got reasonable performance with 16 bit color instead of 24. The new X
doesn't seem to know how to make any of my video work well, another
machine with i965 chipset video is also dead slow at 24 bit. Both
machines run fine on FC8, so I guess all the effort had gone into
features, not performance for the people who aren't gamers and have low
cost video (which used to work fine).

I see when I move a window in 24 bit color the CPU goes 100% busy as
long as a move the Windows. At 16 bit iy takes about 30% of the CPU,
more reasonable.

I reinstalled F9 but I renamed my old home directory, and re-created my
usual user account anew upon install. I'm also not using compiz for now.
The video is fine now. Hope it stays that way when I enable desktop
effects. Before, I could hardly scroll in firefox.
