Where r00t has no land

So you got your new laptop with the new GeForce 9500M GS and you want to run Compiz?
After you have your Xorg server configured (If you haven’t already check the following article: http://pestilence.insert.gr/installing-archlinux-on-acer-aspire-7720g/ ) and ready for composition then you can proceed.
Before you proceed with installing or configuring anything from this, it would be wise to logout from your X session.
For this card (nvidia 9500M GS) nvidia’s 169.12 driver version (available in ArchLinux (Arch Linux) official repository) work just fine, install them and configure them (check previous link).

Please note that nvidia installation contains a bug, to properly install the driver you will need to fix a wrong symlink created by the installation procedure, more specific there is a symlink in /usr/lib/xorg/modules:

libwfb.so -> /usr/lib/xorg/modules/libnvidia-wfb.so.169.12

You need to fix this and point it to:
/usr/lib/xorg/modules/libwfb.so.1.4
So type the following commands:

pestilence ~ cd /usr/lib/xorg/modules
pestilence /usr/lib/xorg/modules sudo rm libwfb.so
pestilence /usr/lib/xorg/modules ln -s /usr/lib/xorg/modules/libwfb.so.1.4 ./libwfb.so

After you update the symlink make sure you re-inject your nvidia module:

pestilence /usr/lib/xorg/modules rmmod nvidia

If you haven’t installed compiz, proceed installing them (I used GNOME (GNU Network Object Model Environment ), so this is a more gnome oriented compiz installation, for your desktop manager check the relevant install guide):

pestilence ~ pacman -S compiz-core
pestilence ~ pacman -S compiz-decorator-gtk
pestilence ~ pacman -S compiz-manager
pestilence ~ pacman -S ccsm
pestilence ~ pacman -S compiz-fusion-plugins-main compiz-fusion-plugins-extra

After you have compiz installed, you can proceed activating them with fusion-icon command (inside gnome):

pestilence ~ fusion-icon

The above command should place a tray icon for compiz in your taskbar, through this icon you can choose to use either metacity or compiz for your window manager.
For the 9500M GS graphics card, also use the following 2 options:

1. Right click on the fusion-icon
2. Select compiz options
3. And make sure the 2 options are selected:
   • Loose binding
   • Indirect Rendering
