Hi,

I don't know how to find the BusID for:

xorg.conf

Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
BusID "PCI:1:0:0"

(Here the one seems not correct) cause there is an warning:
No matching Device section for instance (BusID PCI:0@1:0:1) found

# lspci | grep VGA
01:00.0 VGA

I changed it to

BusID "PCI:01:00.0"

It has problems and generated more than 500 Xorg.*.log files before I reboot.
Xorg.118.log Xorg.158.log.old Xorg.199.log Xorg.238.log.old
Xorg.279.log Xorg.33.log Xorg.47.log Xorg.79.log.old
...

Another question, How do I check whether there is a 3D acceleration,
seems 2D have.

Thanks with best regards,

In your case it has to be

BusID "PCI:1:0:0"

Run fglrxinfo or/and fgl_glxgears. For my card the result is :

display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon HD 5400 Series
OpenGL version string: 4.0.10188 Compatibility Profile Context

Otput from fgl_glxgears is:

Using GLX_SGIX_pbuffer
3236 frames in 5.0 seconds = 647.200 FPS
2949 frames in 5.0 seconds = 589.800 FPS
3225 frames in 5.0 seconds = 645.000 FPS

See this...

$glxinfo | grep direct
direct rendering: Yes
GL_EXT_Cg_shader, GL_EXT_depth_bounds_test, GL_EXT_direct_state_access,
$

If you get the above "direct rendering: Yes" when using glxinfo
then your 3D acceleration may work.

apt-get install mesa-utils , for glxinfo.

I note that when there is only 1 graphics card there is no need to
specify anything.

I run sid + xserver-xorg 1:7.6+9

Thanks for all.

I did not know there is a fgl_glxgears staff, haha ...

well the direct rendering: Yes.
so seems has 3D effect.

Your line is correct. The reason for the warning is that your card is
dual-head, and both heads have their own pci address. The message is
harmless as both fglrx and radeon understand the second head without
needing it configured.

In my case:
01:00.0 VGA compatible controller: ATI Technologies Inc RV350 AS
01:00.1 Display controller: ATI Technologies Inc RV350 AS (Secondary)

Which is why the second controller doesn't show up, apparently it isn't
VGA-compatible :)

Besides the direct rendering, you can also check the opengl version:
$ glxinfo|grep -i opengl
OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on ATI RV350
OpenGL version string: 2.1 Mesa 7.11.1
OpenGL shading language version string: 1.20

Arno
