ATI CrossFire Does Not Support On This Platform When Enabling (Ubuntu Lucid)

**alteredstate** · 07-14-2010, 09:59 AM

I recently installed the ATI Catalyst Driver 8.74 and Catalyst Control Center 10.6 in Ubuntu Lucid, everything works fine so far except the CrossFire. After setting up and then enabling the CrossFire (all in sudo): "aticonfig --cf=on --adapter=0" I received this message in the terminal:
CrossFire chain(s) enabled
CrossFire does not support on this platform

When I run the command: "aticonfig --lsch" I get:
CrossFire chain for adapter 0, status: enabled
and then it lists my adapters in the CrossFire chain.

But "aticonfig --lscs" list the CrossFire status as disabled on the current device". I guess this is apparently different than the chain status “aticonfig –lsch”??

I'm confused at this point because although the terminal says my platform does not support CrossFire, I know it does. I am using an MSI K9A2 Platinum MB and two Sapphire HD3870 cards. The cards are installed in the correct slots (EX1 and EX4 with two ribbon cables joining them). According to the MB manual this is how the CrossFire is enabled as there are no settings in the BIOS to enable it. Any help will be greatly appreciated!

Also stumbled across this in terminal:

user@desktop:~$ sudo aticonfig --lsa

1. 04:00.0 ATI Radeon HD 3870

* - Default adapter
user@desktop:~$ aticonfig --lscc

user@desktop:~$ aticonfig --odgc

user@desktop:~$ aticonfig --odgc --adapter=1
ERROR - Get clocks failed for Adapter 1 - ATI Radeon HD 3870
user@desktop:~$ aticonfig --odgt --adapter=1
ERROR - Get temperature failed for Adapter 1 - ATI Radeon HD 3870

Is this a good indication that something is wrong with adapter 1 graphics card since the "aticonfig --odgt and --odgc" commands work for adapter 0 but not adapter 1? I cannot get a response from adapter 1 but yet the "aticonfig --lsa" command recognizes it as a working adapter. Has anyone had this sort of problem before? Again, I'm just trying to enable CrossFire.

Crossfire does not always work... What is the contents of the command lspci? Also, can you mention the model of motherboard, and cpu?

try this command:

Code:

aticonfig --adapter=0,1 --cfa

Then Reboot and run this command:

Code:

aticonfig --lsch

if that command does not say that crossfire is not enabled, run this command:

Code:

aticonfig --adapter=0,1 --crossfire=on

reboot again, and then run the previous step's command to verify that crossfire is working.

Here's what I got:

user@desktop:~$ aticonfig --adapter=0,1 --cfa
CrossFire chain added
Warning: X needs to be restarted before CrossFire changes take effect.

Reboot

user@desktop:~$ aticonfig --lsch
CrossFire chain for adapter 0, status: disabled
0. 01:00.0 ATI Radeon HD 3870
1. 04:00.0 ATI Radeon HD 3870

user@userdesktop:~$ aticonfig --adapter=0,1 --crossfire=on
Warning: No CrossFire chain defined for master adapter 1
CrossFire chain(s) enabled
CrossFire does not support on this platform
Warning: X needs to be restarted before CrossFire changes take effect.

Reboot

user@desktop:~$ aticonfig --lsch
CrossFire chain for adapter 0, status: enabled
0. 01:00.0 ATI Radeon HD 3870
1. 04:00.0 ATI Radeon HD 3870

However when I run the CrossFire status command I get this:

user@desktop:~$ aticonfig --lscs
Candidate Combination:
Master: 0:0:0
Slave: 0:0:0
CrossFire is disabled on current device
CrossFire Diagnostics:
CrossFire can work with P2P mapping through GART

So I'm assuming that just because the CrossFire chain is enabled doesn't mean the CrossFire is working? This is where I'm stuck as I don't understand why aticonfig would allow the chain to be enabled but not allow me to “flip the switch on” for the CrossFire. Any ideas?

**alteredstate** · 07-18-2010, 02:42 PM

I think I've exhausted all possible problems. I swapped the video cards and still have the same issue. I've also tried loading Ubuntu Karmic x86 & x64 versions and then installing the Catalyst 10.6 but still no luck. I also installed Lucid x86 and...yes you guessed it, no success. This is sucking up a lot of my freetime, why is this so difficult? I didn't have these sort of problems with Windows...I'm half tempted to go back to Windows even though I don't want to but I miss that functionality of certain programs and my hardware.

**oldskool69** · 08-04-2011, 08:41 PM

xD i have the same problem! i think its related to true pcie-express speed of the motherboards pcie slots... or support of p35 chipset... im stuck too and wasted a lot of free time!

BUT!

it can work in windows, so it can work in linux, too!

i think xorg and kms mix up and get confused...

seems to be a problem with 1 monitor / screen...

**m4rtin** · 06-18-2012, 06:16 PM

I have the very same problem as alteredstate. I have Radeon HD 5850 in first x16 PCIe slot of my motherboard(ASUS Crosshair V Formula) and Radeon HD 5870 in the third x16 PCIe slot(based on motherboard manual recommendations): http://i.imgur.com/OKQpS.png

Short system summary can be seen here:

Code:

root@debian64:~# uname -a

model name	: AMD FX(tm)-4100 Quad-Core Processor            
root@debian64:~#

As you can see from lspci(8) output, both graphics cards are detected. Same can be confirmed with aticonfig(I installed the latest AMD proprietary driver for x86-64 architecture with the amd-driver-installer-12-4-x86.x86_64.run package):

Code:

root@debian64:~# aticonfig --list-adapters
* 0. 01:00.0 ATI Radeon HD 5800 Series 
  1. 07:00.0 ATI Radeon HD 5800 Series

* - Default adapter
root@debian64:~#

I created a new CrossFire chain:

Code:

root@debian64:~# aticonfig -v --adapter=0,1 --add-crossfire-chain
CrossFire chain added
Warning: X needs to be restarted before CrossFire changes take effect.
root@debian64:~#

Then rebooted my machine and if I check the status of the CrossFire chain, it is disabled:

Code:

root@debian64:~# aticonfig -v --list-crossfire-status
    Candidate Combination: 
    Master: 0:0:0 
    Slave: 0:0:0 
    CrossFire is disabled on current device
    CrossFire Diagnostics:
    CrossFire can work with P2P mapping through GART

root@debian64:~#

Well I should be easily able to turn this on using following command:

Code:

root@debian64:~# aticonfig --adapter=0,1 --crossfire=on
Warning: No CrossFire chain defined for master adapter 1
CrossFire chain(s) enabled
CrossFire does not support on this platform
Warning: X needs to be restarted before CrossFire changes take effect.
root@debian64:~#

I quite don't understand the error complaining about no CrossFire chain defined for adapter 1- this was done with the "aticonfig -v --adapter=0,1 --add-crossfire-chain" command, wasn't it? I reloaded the machine once again and checked back for CrossFire status, but it's still disabled:

Code:

root@debian64:~# aticonfig -v --list-crossfire-status
    Candidate Combination: 
    Master: 0:0:0 
    Slave: 0:0:0 
    CrossFire is disabled on current device
    CrossFire Diagnostics:
    CrossFire can work with P2P mapping through GART

root@debian64:~#
