KWin crash after ATI drivers install

[burkina76]

Ciao,

I tried to install the new ATI drivers (ati-driver-installer-8-11-x86.x86_64.run ) on my F9. I have a Radeon X1300 video card and X.Org X Server 1.5.2.

At first, I tried to produce the packages for F9, supposedly supported by this ATI release:

sh ati-driver-installer-8-11-x86.x86_64.run --buildpkg Fedora/F9

but got an error:

RPM build errors:
Installed (but unpackaged) file(s) found:
/usr/X11R6/lib/libAMDXvBA.cap
/usr/X11R6/lib/modules/extensions/libdri.so
/usr/bin/amdupdaterandrconfig
/usr/bin/amdxdg-su

So, I installed them with the graphical interface and the generic installation.
After the installation I run:

aticonfig --initial

and rebooted the system.
After the boot, the X server did not start.
So I replaced the new xorg.conf with the old, working one.
Now the X server works, but Kwin crashes on logon (error 6). Any clues?
This is the (abridged) debug of the crash:

Thank you,

P.S. After a new instance of aticonfig --initial, the problem was solved and, apparently, the drivers are working ok.
