Hi,<br>
<br>
I'm using Ardour 4.0.0 with a Radeon Mobility X1600 using radeon
open source driver in Xorg 1.12.4, running kernel 3.12.19avl2-pae
(AVLinux 6.04).<br>
<br>
If I use radeon with EXA (so I have radeon.modeset=1, using KMS),
Ardour 4 graphics are slow and I notice a high (50%) processor use
by xorg process. If I use radeon.modeset=0, xorg seems to load the
driver radeon but using the older acceleration architecture I
believe<br>
<br>
[ 20.482] (==) RADEON(0): Using XAA acceleration architecture<br>
[ 20.482] (II) Loading sub module "xaa"<br>
[ 20.482] (II) LoadModule: "xaa"<br>
[ 20.482] (II) Loading /usr/lib/xorg/modules/libxaa.so<br>
[ 20.501] (II) Module xaa: vendor="X.Org Foundation"<br>
[ 20.501] compiled for 1.12.4, module version = 1.2.1<br>
[ 20.501] ABI class: X.Org Video Driver, version 12.1<br>
<br>
and actually the Ardour process uses more CPU (and xorg process,
less), but the graphics and overall user experience is far smoother.<br>
<br>
This is strange since I believed radeon driver should work better
using EXA which enables render acceleration (although I don't really
understand what this implies).<br>
<br>
Well I suspect that I could be getting still far better performance
if I'm able to correctly configure my driver (or xorg) or use
proprietary drivers (but I don't know I there is still support for
my -now- old card). Will I get better performance using the nightly
build with ARDOUR_IMAGE_SURFACE=1? I think I'm going to try it out
and report here.<br>
<br>
Cheers,<br>
Alex<br>

I'm using LInux Mint Debian. Looks like we are rather behind
Fedora. My libglapi-mesa is 9.2.2-1. xdpyinfo says X.org is
1.14.3.<br>
