This is my first time using Ubuntu from Windows and I have just installed Ubuntu 14.04, which I think is excellent.

The only problem is my ATI Radeon 3800 HD Graphics Card that I cannot get installed. I have tried everything I can think off for instance I have downloaded the driver from the AMD website and when I tried to install it AMD says I don't have any supported drivers.

After restarting my computer the screen then goes into big mode and I can't change it back to the original screen setting. I even tried using the terminal, but this does not even appear/open. I have to keep putting in the recovery disc and change back to VGA mode.

I just wonder if Ubuntu does not support this graphics card at all. I have also tried updating the additional drivers.


Didn't know they where worse than AMD. im really stuck when i downgrade. Please see the output below:

    Welcome to Ask Ubuntu! Did you check if all the system requirements mentioned in the release notes of the driver were met? And also did you completely update your PC before attempting to install the driver?

  • Sorry, when i said the screen goes big what i meant to say was that the screen was big that i could not see the top menu or the side bar. When i even pressed for the shortcut to terminal ctl alt t that wouldn't even come up. May 18, 2014 at 13:31

    Hmm... maybe it means your graphic card ain't supported by the driver you installed. Check out my answer below..

So far as I know, your graphic card is not supported my AMD. So installing the proprietary driver would not work. Therefore you need to downgrade your X server and install the Legacy driver.(See this)

But I would suggest you use the open source drivers itself. If your Ubuntu install is not detecting your maximum screen resolution with open source driver(and that is why you are trying to install the driver from AMD site)then follow this answer.

  • Ive started using the opensource driver as AMD did not support the driver yet. Dec 16, 2018 at 9:09
