How-to remove “amd unsupported hardware” without reinstalling the driver?

Question

I installed driver from Additional drivers.... AMD Radeon HD 6450

My resolution is at maximum and Catalist Control Center is working but I have AMD Unsupported hardware image on the right bottom of my screen. How can I remove it without reinstalling driver? Because the drivers from official amd site does not work.

Answer 1

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

I think this is caused by the modaliases that gets your pc to recognise your hardware.

When I have previously removed the ATI catayst application I have had to reinstall the fglrx-modaliases so that it can be installable through the additional drivers at a later stage.

So I would open a terminal up and enter

sudo apt-get remove fglrx-modaliases

This should not remove fglrx but just the modaliases

If there are problems after this obviously reinstall the modaliases

sudo apt-get install fglrx-modaliases

Answer 3

Change the path in the above to /usr/lib/fglrx/xorg/modules/drivers/fglrx_drv.so.

There are two copies.

Answer 4

Check http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx and install it manually.

I have the same problem, but the controller works properly.

Answer 5

I had the same problem, and also another one that you seem to also have at the same time: not knowing how to install the right AMD Radeon HD 6450 driver. As a consequence, when I tried to install Ubuntu 10.10, it froze just after the login screen and when I tried to install Ubuntu 11.10, it did not even arrive to the login screen.

Here is what I did, which solved the problem:

• using another computer, download the latest proprietary driver from ATI on the official site. In my case I had to download it from here.
• put the driver on a USB key
• reboot the computer we want to repair
• in the grub menu, select the recovery mode. This results in arriving at a command line interface. This is a proof that the Ubuntu operating system is functioning but that the problem is indeed the graphical card.
• uninstall all previous versions of flgrx by launching sudo apt-get remove flgrx for example
• mount the USB key with something close to mkdir /mnt/usb followed by sudo mount /dev/sdb /mnt/usb. Another way for this little step is explained here.
• use the cd command to place yourself in the folder where the downloaded driver is
• if necessary, make the driver be executable with something like chmod +x ./ati-driver-installer-11-11-x86.x86_64.run
• execute the driver using sudo ./ati-driver-installer-11-11-x86.x86_64.run
• follow the instructions given on the installer
• if this step did not work, you may want to try sudo ./ati-driver-installer-11-11-x86.x86_64.run --force instead
• reboot your computer

Then your two problems should both be solved!
