I have problems with ati+compiz

i try:

LD_LIBRARY_PATH=/usr/X11R6/lib
SKIP_CHECKS=yes
export LD_PRELOAD=/usr/lib/FGL.renamed.libGL.so.1.2
emerald --replace &
LIBGL_ALWAYS_INDIRECT=true compiz --no-libgl-fallback --ignore-desktop-hints --replace

and...

compiz (core) - Warn: Unknown option '--no-libgl-fallback'

compiz (core) - Fatal: No valid GL extensions string found.
compiz (core) - Error: Failed to manage screen: 0

I use Slackware Current and new ati driver Ati 7-12 (driver link (http://ati.amd.com/support/drivers/linux/linux-radeon.html))...

tanks...

[adamk]

There are a couple of odd things going on here.. You are setting the LD_LIBRARY_PATH to /usr/X11R6/lib but then you are LD_PRELOAD'ing a libGL file under /usr/lib. In addition, you are trying to use --no-libgl-fallback, which is an option specific to opensuse :-)

Let's start with the basics... Are your 3D drivers installed properly? What's the output of 'fglrxinfo'? What's the output of 'locate libGL.so.1.2'?

What's the output from 'Xorg -version'?

And what's the output from just 'LIBGL_ALWAYS_INDIRECT=true compiz --replace --sm-disable ccp &'?

[adamk]

I was worried about that... The fglrx drivers do not support AIGLX on X server 1.4.0 and higher. Sorry, but to use AIGLX with fglrx, you need to downgrade to X server 1.3.0.

Adam

[hersonls]

Tanks, its work now...
but i have one problem with speed... my driver is ATI 1100 and i play games very good, but the compiz is Slowly... some help for this?

[adamk]

Unfortunately, compiz is just slow with that driver using AIGLX. There's not much that can be done about it other than to wait for AMD to fix the problem.
