Ubuntu – Proprietary drivers don’t work with AMD Radeon HD 7640G on Ubuntu 12.10


My setup

First off, my apologies if this is a duplicate but I could not find anything specific regarding my graphics card.

So as the title states, I have purchased a new laptop with an AMD Radeon HD 7640G graphics card. (detailed specifications).

I was able to install Ubuntu on the laptop without any problems whatsoever. My next step was enabling the proprietary drivers (Catalyst 12.11) from the Additional drivers menu (jockey). That's where I got stuck.

The Open Source drivers do not appear to support the graphics card mode

The problem

After installing FGLRX, my notebook now doesn't boot up properly anymore. It displays the splash screen but then gets stuck in a shell. At this point I am not able to enter any commands so I'm forced to do a hard reboot and get into recovery/low graphics mode.

Shown in this image below:

After Catalyst 12.11 driver install

I would love to make FGLRX work.

What I've tried so far

I followed the instructions provided by this Q&A and the official Ubuntu guide, but to no avail.
Both sources offer the same basic steps, which I think I took:

  • Get the latest catalyst driver from AMD website (Catalyst 12.11 beta 8),

  • Set the .run file to be able to execute (chmod etc)

  • run it in terminal

  • initialise the driver by: sudo amdconfig --initial -f or sudo aticonfig --initial -f

  • Reboot

Is there anything I'm overlooking. Any suggestion on what I might be doing wrong? Or is there maybe another way of installing FGLRX?

I might not have provided enough details in this post. So if there's any other information you need to help me with this problem, please let me know and I'll be glad to add it.

Right so an update. I have managed to install the 12.10 driver from catalyst and when I reboot, I get the login screen etc. After I log in, it loads my desktop background, but it does not appear to load unity or anything else. Literally just gets stuck on a desktop background.

Another update:

Following the 'Answer' marked below this, for both the catalyst 12.10 and 12.11 beta, the problems are still persistent:

Catalyst 12.10

It would appear that Catalyst 12.10 is consistent and can get me as far as the log in window. After logging in I get the desktop background but nothing else. From here I was able to load Terminal and run ps -ef | grep unity which confirms unity has not launched.

Catalyst 12.11

After attempting a few variations for installing this driver, it still passes the Ubuntu splash screen and then fails to progress any further. Shown in the image above.

Best Answer

I was not using the same graphics card, but I was able to install the BETA AMD drivers on 12.10.

Main Instructions

However, I had a few issues, so here were my modifications to the steps given in the 12.10 section.

  • Purge Items per instructions (from the 12.04 LTS section)
  • Install Dependencies (from the 12.04 LTS section)
    • MODIFY sudo apt-get install ia32-libs; those libs didn't exist. I went to the package manager and found ia32-libs-multiarch that are mentioned in the 64-bit section; I am 32bit. I didn't install from command line.
  • MODIFY, I didn't do the WGET or chmod on the 12.6 version shown in the steps, I went to AMD's site and downloaded the BETA drivers. (Follow link in the second COMMENT from "thelastshadow").
  • Ran commands to install/reboot.

Do everything in that second link, I rebooted with new drivers, then ran the script to uninstall the watermark. So, all the right steps are here and answered, just have to jumble them up a bit! BTW, the 12.6 and the 12.10 drivers DID NOT work for me. I had to uninstall them and follow the same steps with the beta drivers and they worked fine. I did the steps exactly as shown using the 12.6 with the wget and didn't have success.

Hope that helps!
