Topic: 7850 on debian - "Your graphics adapter is not supported by this driver" (Read 1687 times)

Hi,

I've managed to get cgminer and several different cards (including this one) working on Windows, however I am now trying to get a HD 7850 working on Debian 7.3 64 bit (desktop, not headless server).

I have installed debian, and tried to install the latest drivers from AMD's website (amd-catalyst-13.12-linux-x86.x86_64.run), and got the following error:
"Your graphics adapter is not supported by this driver. Installation will not proceed"

So I took a step back and have been trying to follow the steps from this guide:

sudo nano /etc/apt/sources.list
    For each line that starts with deb, add the following to the end: contrib non-free
sudo apt-get update && apt-get upgrade
sudo apt-get install bzip2 fglrx-driver libcurl4-openssl-dev libncurses5-dev libudev-dev ntp screen unzip xdm xorg
sudo apt-get purge libfglrx
sudo apt-get install firmware-linux-nonfree
sudo apt-get clean

wget --referer=http://www2.ati.com http://www2.ati.com/drivers/linux/amd-driver-installer-12-8-x86.x86_64.zip
unzip amd-driver-installer-12-8-x86.x86_64.zip && sh amd-driver-installer-8.982-x86.x86_64.run --force
    When the installer starts, just press Enter on any screens until the driver finishes installing.
    Initial graphics card setup (also do this after adding or removing cards):
sudo rm /etc/X11/xorg.conf && aticonfig --adapter=all --initial
ENDQUOTE

so all of those steps go fine (including installation of the 12-8 version of the amd drivers), except the last command, where it complains that /etc/X11/xorg.conf doesn't exist. I deleted that part and re-ran just sudo aticonfig --adapter=all --initial, and got the error:
"aticonfig: No supported adapters detected"

sudo lspci yields:

To my untrained eye, it looks like the amd adapter isn't showing up in the list of connected hardware, so I rebooted and tried lspci again - same issue.

I tried the whole proccedure again, with a different HD 7850 (same make - MSI - and model, but different card) in a different computer, also running net-install of debian wheezy 7.3 64bit and ran into exactly the same set of issues (latest driver doesn't recognise the card and won't install; previous driver installs but card doesn't show up in lspci - or cgminer - afterwards).

I'm not sure what else to look for - I've searched around and can't seem to find any reports that the HD 7850 won't work with the latest drivers, nor reports of others having issues with the HD 7850 not showing up after successful installation of the 12-8 amd drivers.

Suggestions appreciated!
