Squeeze.GNOME. Correct compiz configuration.
 

Hello, list!

Please, help to install and configure compiz manager correctly for
Debian Squeeze.
Googling got me some recommendations, kinda:

1. Open a terminal and type sudo su
2. Type gedit /etc/X11/xorg.conf

3. Add the following option under Section "ServerLayout"

Option "AIGLX" "true"

4. Add the following options under Section "Device"

Option "AllowGLXWithComposite" "true"
Option "RenderAccel" "true"

5. Add the following options under Section "Screen"

Option "XAANoOffscreenPixmaps"
Option "AddARGBGLXVisuals" "true"

6. Add the following lines to the end of the file

Section "Extensions"

Option "Composite" "Enable"

EndSection

But the is no such file:

# ls -la /etc/X11/

What is the modern and correct way to accomplish a compiz
implementation into Squeeze?
Hardware:
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon
Mobility M7 LW [Radeon Mobility 7500]
Subsystem: IBM Device 0527
Kernel driver in use: radeon
# glxinfo | grep rendering
direct rendering: Yes

And I had have a fully working compiz under Lenny at this hardware.
Worked like a charm.

At the same time ./compiz-check now shows:

$ ./compiz-check

Gathering information about your system...

Distribution: Debian GNU/Linux (squeeze/sid)
Desktop environment: GNOME
Graphics chip: ATI Technologies Inc Radeon Mobility M7 LW
[Radeon Mobility 7500]
Driver in use: radeon
Rendering method: AIGLX

Checking if it's possible to run Compiz on your system...

Checking for texture_from_pixmap... [ OK ]
Checking for non power of two support... [ OK ]
Checking for composite extension... [ OK ]
Checking for FBConfig... [ OK ]
Checking for hardware/setup problems... [FAIL]

There has been (at least) one error detected with your setup:
Error: Software Rasterizer in use

Would you, please, help me to bring all this to work? At least, point
me to actual document how to get compiz working on Squeeze.
Thank you very much!

Yes, this is a first link I have checked, but there about xorg.conf
also. I can not find that file in /etc/X11 anymore. Actually, I cannot
find it at all.

I have installed:

compizconfig-settings-manager - Compizconfig Settings Manager
compiz-fusion-plugins-main - Compiz Fusion plugins - main collection
compiz-core - OpenGL window and compositing manager
compiz-gnome - OpenGL window and compositing manager - GNOME window decorator
compiz-gtk - OpenGL window and compositing manager - Gtk window decorator
compiz-plugins - OpenGL window and compositing manager - plugins
compiz - OpenGL window and compositing manager
libdecoration0 - Compiz window decoration library
python-compizconfig - Compizconfig bindings for python
libcompizconfig0

But compiz does not works:

$ compiz --replace
compiz (core) - Fatal: Software rendering detected.
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0
Launching fallback window manager

Correct me, if I am wrong, but the question is how to enable hardware
3D support in 'radeon' video driver, which is in use by my Radeon
Mobility 7500? Or, if it is impossible, how to change video driver,
which will support hardware 3D and will works with compiz?

I am asking, because I had have working compiz with Debian Lenny.
AFAIR, I have added those parameters from wiki page you have
mentioned, installed compiz, that is it. I do not remember any trouble
or any questions about it.

Please, help to bring compiz to live in Debian Squeeze.

Run "X -configure" to create a new xorg.conf

#X -configure
#mv ~/xorg.conf.new /etc/X11/xorg.conf

The system does not allows me to do that:
# X -configure

Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.

How to close current X session and do not start a new one automatically?

I am continue googling and that brings more questions:

In dmesg I have noticed that info:

dmesg |grep radeon

[ 6.788966] radeon 0000:01:00.0: Disabling GPU acceleration

R100_cp.bin is a part of firmware-linux-nonfree package.

# dpkg -l |grep firmware
ii firmware-ipw2x00 0.27
Binary firmware for Intel Pro Wireless 2100, 2200 and 2915

If I will install this package into the system, does it resolve the
problem with compiz malfunctioning? Sorry, if I am asking something
obvious, but I am not familiar with linux and do not want to do
something harmful to the system, which I have installed with so much
trouble. The question is, if this is a key component for 'radeon'
video driver of my laptop videoboard, why it is not installed by
default?

You can't configure X while running it.
Try:

# /etc/init.d/gdm stop
# X -configure
# mv ~/xorg.conf.new /etc/X11/xorg.conf
# /etc/init.d/gdm start

Yes, it is no more "by default", but you can create it.

3D should be enabled by default when using radeon driver, I wouldn't
bother about that (you can check it with "glxinfo | grep -i render").

You have to follow the same steps. If "/etc/X11/xorg.conf" is not there,
just create it and add the required sections.

Done. Next, will try to add the options mentioned on wiki.

It is not enabled by default, that a problem is.

$ glxinfo | grep -i render
direct rendering: Yes
OpenGL renderer string: Software Rasterizer

It is because needed module for hardware acceleration does not loaded:

[ 7.667868] platform radeon_cp.0: firmware: requesting radeon/R100_cp.bin
[ 7.691511] radeon_cp: Failed to load firmware "radeon/R100_cp.bin"
[ 7.691602] radeon 0000:01:00.0: failled initializing CP (-2).
[ 7.691643] radeon 0000:01:00.0: Disabling GPU acceleration

>From that strange fact we have this situation:

libGL: OpenDriver: trying /usr/lib/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib/dri/swrast_dri.so
display: :0 screen: 0
direct rendering: Yes

As here we may see, it is software rasterisation enabled instead of hardware.

Correct me, if I am wrong, but I think it is useless until hardware
rendering will be available and turned on.

By reading this:

http://dri.freedesktop.org/wiki/glxinfo

It seems to enable software rendering, yes.

Oh, I see ;-(

Then you should first fix that "missing firmware" issue to get full 3D
hardware acceleration:

Installing proprietary firmware
