Hardware acceleration with xf86 and ATI video card

I've been googling this a lot. My video card is Radeon Mobility HD 45xx and I'm using xf86-video-ati (this is a laptop).

$ lspci | grep VGA
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV710/M92 [Mobility Radeon HD 4530/4570/545v]
$ X -version
X.Org X Server 1.14.1
Release Date: 2013-04-17
X Protocol Version 11, Revision 0
Build Operating System: Linux 3.8.7-1-ARCH x86_64 
Current Operating System: Linux meshuga 3.9.5-1-ARCH #1 SMP PREEMPT Sat Jun 8 09:22:45 CEST 2013 x86_64
Kernel command line: BOOT_IMAGE=/vmlinuz-linux root=UUID=19e8638c-edcb-44d2-b850-f2a0e8a43823 ro quiet
Build Date: 17 April 2013  02:37:06PM
 
Current version of pixman: 0.30.0
	Before reporting problems, check http://wiki.x.org
	to make sure that you have the latest version.

Problem is I can't use WebGl and most 3D applications. Also when I use dual screen, the laptop screen overlaps the external screen by a couple of pixels; people out there say this issue may have something to do with drivers. Due to catalyst being incompatible with xorg 1.14 I have to use xf86 video drivers. Is there any way of enabling hardware acceleration?

Re: Hardware acceleration with xf86 and ATI video card

As I posted here for someone else, you're video card is supported just fine. You should have hardware accelerated 3D graphics with the open source "radeon" driver.

What is the output of "glxinfo | grep direct"?

Do you have a "/etc/X11/xorg.conf" file? Because you shouldn't...

$ glxinfo | grep direct
direct rendering: Yes

And no, /etc/X11/xorg.conf doesn't exist .

Great! Then you have hardware accelerated 3D graphics!

What do you mean by "I can't use WebGl and most 3D applications"? Do you mean, you install them and then you can't find the binary? Do you run a 3D application and the the monitor turns black?

I'm using google-chrome and webgl applications simply don't run. chrome://gpu/ tells me this:

Graphics Feature Status
Canvas: Software only, hardware acceleration unavailable
Compositing: Software only, hardware acceleration unavailable
3D CSS: Unavailable. Hardware acceleration unavailable
CSS Animation: Software only, hardware acceleration unavailable
WebGL: Unavailable. Hardware acceleration unavailable

I tested webgl apps here http://www.chromeexperiments.com/webgl.

Re: Hardware acceleration with xf86 and ATI video card

Have you tried chromium, which Arch builds from source, instead of chrome, which google builds with who knows what options?
