How to remove the “AMD Testing use only” watermark?

I've installed the latest catalyst driver (beta) following the step in this guide for Ubuntu Quantal Quetzal.
My system is 64 bit and my graphic card is an ATI RadeonHD 6670, this g.c. is Officially Supported (Catalyst & Open Source), you can confirm that from this AMD Linux Community thread.

I don't have any problem, except the AMD testing use only watermark. I see the following frame in any stage into the OS (logged, unlloged, etc.) except in the terminals.

I found different versions of how to remove this image, but this change according to the system, so I want an answer from this popular (trusted) site.

• How to solve this issue in Ubuntu 12.10 32b?
• This procedure is different in a 64b system?

The script above did not work for me. However I found a much simpler answer here

Edit the ati signature file:

sudo gedit /etc/ati/signature

and just replace the "UNSIGNED" line with the following code

9777c589791007f4aeef06c922ad54a2:ae59f5b9572136d99fdd36f0109d358fa643f2bd4a2644d9efbb4fe91a9f6590a145:f612f0b01f2565cd9bd834f8119b309bae11a1ed4a2661c49fdf3fad11986cc4f641f1ba1f2265909a8e34ff1699309bf211a7eb4d7662cd9f8e3faf14986d92f646f1bc

It worked fine for me.

The resulting file should be 238 bytes long for it to work.

For Ubuntu 12.10 64-bits

I fixed it using the following script. Found At: http://ubuntuforums.org/showthread.php?t=2076381

Under Ubuntu 12.10 x64 and driver AMD 12.11 beta.

#!/bin/sh
DRIVER=/usr/lib/fglrx/xorg/modules/drivers/fglrx_drv.so
echo "Come on AMD!"
echo "Removing AMD logo from "$DRIVER
for x in $(objdump -d $DRIVER|awk '/call/&&/EnableLogo/{print "\\x"$2"\\x"$3"\\x"$4"\\x"$5"\\x"$6}'); do
    sed -i "s/$x/\x90\x90\x90\x90\x90/g" $DRIVER
done
echo "Reboot computer to finish"

Copy and paste the code from above into a new file, save it, and do sudo bash filename in the terminal.

For Ubuntu 11.04

I found this elsewhere on the net and I ran it on a Ubuntu 11.04 - it works great!

Put this in a text file and save it (call it fixwatermark.sh):

#!/bin/sh
DRIVER=/usr/lib/fglrx/xorg/modules/drivers/fglrx_drv.so
for x in $(objdump -d $DRIVER|awk '/call/&&/EnableLogo/{print "\\x"$2"\\x"$3"\\x"$4"\\x"$5"\\x"$6}'); do
sed -i "s/$x/\x90\x90\x90\x90\x90/g" $DRIVER
done

With terminal go to the location where you saved it and do a

chmod +x fixwatermark.sh

to make it executable and a

sudo ./fixwatermark.sh

to let the script remove the enableLogo
