How to remove the “AMD testing use only” watermark from Debian Wheezy

This script should do the trick:

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

Or you can download it here. And run it as root.

  1. thank you! so much for this great article a day after published :] i accidently downloaded the ati beta graphics driver for ubuntu and found myself with the dreading amd/ati watermark which was a pretty upsetting feeling but this easy script fixed the issue thank you bud oh yeah! dont run in x server run in terminal keep it up ill bookmark this blog and you should take a look at mine also Computer Repair in San Antonio Blog

  2. For 64 bit versions, change the following line for your lib64 (confirmed on Fedora 17 and Ubuntu 12.04):


  3. Titan, you are correct. In fact I first got this script from a Fedora user. So I can confirm for Fedora (idk about ubuntu) that you do have to s/lib/lib64. According to otto (see below) the script works as is for ubuntu 12.04.

    So, please note the original script I posted is for 64-bit Debian Wheezy where the 64bit lib dir is simply lib and not lib64.

  4. Good post, the fix/hack works. I tried in ubuntu 12.04 (64bits) with out changing anything to the script and it works.

    Your script didn’t work for me (Ubuntu 12.04, AMD64). This one, from, worked:

    for x in $(objdump -d $DRIVER|awk ‘/call/&&/EnableLogo/{print “\\x”$2″\\x”$3″\\x”$4″\\x”$5″\\x”$6}’Smilie: ;); do
    sed -i “s/$x/\x90\x90\x90\x90\x90/g” $DRIVER

  5. Thanks, really useful!

    About the lib/lib64 problem, why not changing the script like that so we don’t have to bother :

    instead of : DRIVER=/usr/lib/xorg/modules/drivers/
    this : DRIVER=`find /usr -name ‘’ 2> /dev/null`

    like that would be found wherever it is within /usr i think.

  6. I’m getting this error:

    objdump: ‘/usr/lib64/xorg/modules/drivers/’: No such file

    Using ubuntu 12.04 x64, any ideas?

  7. Wow,
    thank you all, it worked like a charm!
    Smilie: :) I have fedora 17 64bit and the file was indeed in lib64, not lib Smilie: :)

  8. Check /usr/lib/ or /lib. Poke around. Each distro is a little different.

  9. Hello guys,

    It works on me. I change the lib to lib64, my OS is Ubuntu 12.10. Maybe the important is the file because when I browse the root folder through /usr the lib64 folder is just a link. I think both ways will work if not thats the time you have to change. Anyway thank you guys for this script, it helps me get rid the AMD watermark.
