Hi,

I was minutes ago affected by the same problem (NVIDIA here) when
running compiz:

/usr/bin/gtk-window-decorator: symbol lookup error: /usr/bin/gtk-window-
decorator: undefined symbol: decor_blend_border_picture

This is what I did:

1.- Disable compiz by running

$ metacity --replace

2.- Uninstalled compiz completely

$ sudo apt-get remove --purge compiz

It will uninstall libdecoration0 as well.

3.- Checked for /usr/lib/libdecoration* files. If there's any, please
move them to a safe place. Nothing will break.

4.- No libdecoration files should be present on /usr/lib

5.- Ran the following

$ sudo apt-get clean 
(to get a clean headstart and no packages previously downloaded should be there)

$ sudo apt-get install compiz

6.- Check for /usr/lib/libdecoration* files. There should be some of
them now:

jci@zaphod:/$ ls /usr/lib/libdecoration.so*
/usr/lib/libdecoration.so    /usr/lib/libdecoration.so.0.0.0
/usr/lib/libdecoration.so.0

7.- Just in case

$ sudo ldconfig

8.- And theeeeeeen

$ compiz --replace

Starting gtk-window-decorator
/usr/bin/compiz.real (video) - Warn: No 8 bit GLX pixmap format, disabling YV12 image format

meaning compiz should be working again.

** Changed in: compiz (Ubuntu)
