Intel GMA X4500 garbled graphics under BT4 Final /w fix

With BT4 Final installed the video would be garbled while using the vesa driver, the video device is a Intel GMA X4500 (see lspci -vv output below). The Intel driver would refuse to load with a (EE) NO devices detected. After trying many different things I ended up doing to following to fix it:

apt-get install the following(not all may be necessary):

x11proto-core-dev
x11proto-fonts-dev
x11proto-gl-dev
x11proto-input-dev
x11proto-randr-dev
x11proto-render-dev
x11proto-video-dev
x11proto-xext-dev
x11proto-xf86dga-dev
x11proto-xf86dri-dev
x11proto-xf86misc-dev
x11proto-xinerama-dev
xserver-xorg-dev
libdrm-dev

#### Now do:

mkdir ~/build
cd ~/build

#OPTIONAL BACKUP: tar -cvvzf libdrm-backup.tgz `find / -name libdrm\*`


wget http://dri.freedesktop.org/libdrm/libdrm-2.4.20.tar.gz
tar -xvvzf libdrm-2.4.20.tar.gz
cd libdrm-2.4.20
./configure
make
make install

cd ~/build


wget http://xorg.freedesktop.org/archive/...l-2.7.1.tar.gz
tar -xvvzf xf86-video-intel-2.7.1.tar.gz
cd xf86-video-intel-2.7.1
./configure
make

#OPTIONAL BACKUP: tar -cvvzf ~build/x11modules.tgz /usr/lib/xorg/modules

cp src/.libs/intel_drv.so /usr/lib/xorg/modules/drivers


#backup and remove /usr/lib/libdrm*

ldd /usr/lib/xorg/modules/drivers/intel_drv.so
#make sure it is using /usr/local/lib/libdrm* and not other directories

#make sure your /etc/X11/xorg.conf is using the intel driver.

Hi i been following your how to get this fixed and so far it is working great. except the following error occurs when i run the following command you stated
cp src/.libs/intel_drv.so /usr/lib/xorg/modules/drivers

cannot stat 'cp src/.libs/intel_drv.so': no such file or directory.
can you please advise me on what i have done wrong.

that resolve my problem thanks
