FWIW, Xv performs colour space conversion (from YCbCr to RGB) as well as scaling. Might not seem like much but it does offload a couple of gigaflops/sec of work, which is a big deal for most CPUs (and is a big deal for *all* CPUs if the code isn't making full use of SIMD extensions and multiple cores).
The performance was abysmal. /
It would give some empty screen on top of the normal desktop if I ever activated compiz.
Next to that, simple things as scrolling or moving windows around was really slow (now I'm talking about metacity). The vesa driver gives a smoother experience IMO.
So there are 2 options: either I didn't do something I should've done (in which case these directions are incomplete) or they just don't work satisfactorily yet with R7xx hardware (it _is_ marked experimental after all).
JeanPaul, Compiz uses OpenGL for compositing and that will be running software rendering right now (ie don't bother).
When you say performance was abysmal, which kind of operations are you talking about ? If they're anything but 3D (which isn't accelerated yet) can you post X log and dmesg output ?
Here are the Xorg.0.log and the dmesg output.
I've taken both snapshots of these logs while having fglrx uninstalled and my xorg.conf set to
@rahman.duran:Code:Section "Device" Identifier "Configured Video Device" Driver "radeonhd" Option "AccelMethod" "exa" # default shadowfb Option "DRI" "on" EndSection
Yeah, I just did the whole process again, just to be sure I didn't miss anything on this page. But I followed those instructions to the letter.
You should note that I have a R7xx gfx card, for which the support is still quite incomplete, and I imagine that the HD3200 igp uses the R6xx driver. That might make a huge difference.
