can you pastebin the output of:

Thanks

You may need to reinstate your video driver.

sudo lshw -C video

The xorg.conf File :

# 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.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# 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

okk the UNCLAIMED lines are not good, this is why you are not getting video accelleration and why Compiz is not running.

If you run:

gksudo gedit /etc/X11/xorg.conf (For GNOME) or
kdesudo kate /etc/X11/xorg.conf (For KDE)

and change this:

Section "Device"
 Identifier "Configured Video Device"
EndSection

to this:

Section "Device"
 Identifier "Configured Video Device"
 Driver "intel"
EndSection

save the new file, close the editor and reboot.

Still having the same problem and still having the UNCLAIMED lines in the output of the : sudo lshw -C video command

Did a bit more research. Looks like you lucked out:

I suggest dropping back to intrepid or ditch compiz (I suggest ditching compiz as it is GARBAGE)

No need to skip check.
Try this:
add to device section in xorg.conf and restart Xserver.

Option "AccelMethod" "EXA"

Compiz blacklists by the hardware, not how the xorg.conf is configured. That is not even the reason it is blacklisted in Ubuntu.

thanks all for your reply but none of this solve my problem

i tried to install emerald and then the compiz effects works again :o

anyway ...

thanks again for all of you
