FGLRX detecting one of two GPUs
 
Hello everyone!

I have two ATI graphics cards running in crossfire and three monitors. I am using the latest version of Linux Mint and all packages are up to date.

GPU one is a HD6950 and is properly running the single monitor connected to it.
GPU two is a HD6800 and is not functioning. It has two monitors connected to it.

My issue is that FGLRX only detects the primary graphics card however LSPCI indicates that all is well with both devices.

What should I do?

Thanks in advance!

You cant run crossfire with a 69XX + 68XX as far as I know.

What are the system requirements for AMD CrossFire™?

The minimum requirements to run AMD CrossFire are:

2x or more AMD Radeon™ HD2000 series or greater graphics cards that are within the same family model number. E.g. 2 x AMD Radeon HD6770
http://support.amd.com/us/kbarticles...ssFireFAQ.aspx

'Family model' basicly means 'the cards need to start with the same 2 digits' (so crossfire 6870 + 6850 is possible, 6870 + 6950 isnt)

The same configuration worked perfectly for windows XP and 7. Crossfire appeared to be working properly on those OSes.

I will remove the crossfire link and provide a update in a few minutes.

No change after removing the crossfire link. Device is still listed in lspci.

No obvious issues that I can see with the exception that my displays are not being detected/working.

Any other ideas?

I dont think you had crossfire running in XP or 7.

Thats besides the point, the second graphics card is not functioning. At this point I don't care about crossfire, I just need my other monitors online.

Still attempting various things and I have busted my distro twice now. Any ideas would be helpful.

Could you give us the output from
Code:
lspci -vn | grep  VGA
aticonfig  --list-adapters
Cheers

anon019 04-03-2013 04:26 PM
Here is the output from those commands.

As I said, lspci lists it but I can not get the driver to output.

Code:
longbow12 wyatt # lspci -vn | grep  VGA
        Flags: bus master, VGA palette snoop, 66MHz, medium devsel, latency 64
01:00.0 0300: 1002:6719 (prog-if 00 [VGA controller])
07:00.0 0300: 1002:6738 (prog-if 00 [VGA controller])

longbow12 wyatt # aticonfig  --list-adapters
* 0. 01:00.0 AMD Radeon HD 6900 Series
  1. 07:00.0 AMD Radeon HD 6800 Series

* - Default adapter

Use a service like http://pastebin.com/ to show us your /var/log/Xorg.0.log file.

Well your xorg.conf makes no reference to a second GPU, so of course nothing is going to get output. Pastebin the config file. How did you create the file?

gdejonge 04-03-2013 09:51 PM
You should be able to configure both cards with aticonfig.
Code:
aticonfig --adapters=all --original
It should create a xorg.conf for both cards.

I thought the same but apparently the aticonfig does not reconize "--adapters=all".
Code:
longbow12 wyatt # aticonfig --adapters=all --original
aticonfig: unrecognized option '--adapters=all'
aticonfig: parsing the command-line failed.

anon019 04-04-2013 12:14 AM
Played around with various settings and managed to break the system again. Thank god for backups.

Toying with any option that would make sense with aticonfig is returning with no avail.

gdejonge 04-04-2013 10:46 PM
Sorry, my bad.
Should be --adapter=all without the 's'.
And the --original should be --initial.

Cheers.
