Comment 115 for bug 147943

I've put a copy of my lspci, if it can help.

As I've explained, I use KDE with driver nvidia-glx-new. The theme I use is kde-window-decorator, but the same thing actually occurs with Emerald as a window decorator, or with gtk-window-decorator.
Note that it does not happens on the first startup of KDE with Compiz, but it always happens if you log out and re-log in with the same login and password, even if compiz is set as an app that must not be restarted by the ksm server.

The manipulation I've used in order to set compiz consists in editing my ~/.bash_profile file and add the following line :
export KDEWM=/usr/bin/compiz --replace

Some command results :
julien@pcathlon64:~$ apt-cache policy compiz-core
compiz-core:
  Installé : 1:0.6.0+git20071008-0ubuntu1
  Candidat : 1:0.6.0+git20071008-0ubuntu1
 Table de version :
 *** 1:0.6.0+git20071008-0ubuntu1 0
        500 http://eu.archive.ubuntu.com gutsy/main Packages
        100 /var/lib/dpkg/status

Note that the same configuration works well if I use kwin as my window manager, and it worked also well under Feisty with Compiz enabled.

I've attached my lspci if it can help.

Rgds,

Julien.
