[SOLVED] Compiz won't work after reinstallation of Ubuntu and restoration of home fol

[digitalcircuit36939]

After encountering difficulties with compiz (http://ubuntuforums.org/showthread.php?p=4881941) in Hardy Heron after upgrading from Gutsy Gibbon to it, I reinstalled Ubuntu Hardy Heron by deleting the partitions (root and swap) in Vista and booting from the install CD.
Compiz then worked. After I restored my home folder and rebooted, compiz wouldn't work, exiting with the following message:

sly@Ubuntu-desktop:~$ compiz --replace

3D games work fine.

Could you post the contents of your /etc/X11/xorg.conf file? I have a susicion the problem lies there.

Here it is:

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

You should add

Option "AddARGBGLXVisuals" "True"

to the device section, and add

Section "Extensions"
        Option "Composite" "Enable"
EndSection

at the end.

I'll try that, but Compiz works on new users. It only didn't work after I restored my home folder, so how does that affect /etc/X11/xorg.conf

[Edit] It doesn't work

It wouldn't, you are right, but, I didn't realize that compiz only didn't work for one user. Try backing up your compiz profile, and then nuking the contents of

~/.config/compiz/compizconfig/
