12.10 x64 ati proprietary drivers hd 6 series

[paridoth]

I am trying to get the proprietary drivers for my radeon hd6850 to work but am having some problems, when I use update manager to switch to either of the two proprietary drivers, after I reboot, my computer is slow to scroll windows in nautilus or even windows on the desktop. running fglrxinfo gives me errors. I was wondering if there a a special method I am supposed to use to get the proprietary drivers working?

paridoth@basement-ubuntu:~$ fglrxinfo

  Minor opcode of failed request:  66 ()

I am still on 12.04, since my last attempt on getting my 6850 working in 12.10 wasn't so great.

That being said, did you check out the wiki? https://help.ubuntu.com/community/BinaryDriverHowto/ATI

The isntructions there are pretty much complete. Make sure you remove all old fglrx drivers before installing the new ones, especially if you installed from the AMD website.

Hi again,

I finished installing 12.10 finally, but I had to use the drivers included in the ubuntu repos. I could not use the latest driver on the AMD website.

What I did to make it work:

Uninstall any AMD driver I had installed up to now.

Install the kernel headers.

sudo apt-get install linux-headers-generic

Install the driver from the Software Sources app. (Search for 'soft' in the Unity Lens). Under the Additional Drivers tab, select the 'fglrx-updates' (last one) driver.

Reboot and everything was working for me.

For good measure I also installed the VAAPI for video acceleration.

sudo apt-get install xvba-va-driver libva-glx1 libva-egl1 vainfo

Hope this helps.
