Xorg using 30% cpu when idle,slow performance and video problems

Question

I'm having a problem with Xorg, I don't know what it is but I guess it has something to do with configuration problems because in Ubuntu eerything works out of the box.
My problems are these:
1. Xorg is using arround 30% cpu when the computer is idle and very simple animations in kde like minimize a window are performed very poorly.
2. Compiz' performance is very poor and chopy
3. h264 videos are not wachable. it feels like watching 3fps videos.
as i mentioned above, i don't have any of these problems with ubuntu.
Here's my xorg.conf file:

Answer 1

Experiment with section module. My i945 is
load "dbe"
load "freetype"
subsection "extmod"
option "omit xfree86-dga"
endsubsection
Try to comment busid in section device and add another section device before your existing one
section "device"
identifier "tommy"
vendorname "unknown"
boardname "unknown"
driver "vga"
endsection
Try the drivers i810 and vesa in section device
My file was created by xorgconfig (run this from the console)
