Ok, so I finally seem to have gotten my graphics drivers installed and running correctly, but now I'm facing an issue with getting Crossfire enabled.
My laptop has 2x 5870 graphics cards in it and I'm trying to enable both for Crossfire, but I don't believe anything I'm trying is working. The in-game performance I'm getting seems to indicate that crossfire definitely isn't working, along with checking some of the settings that I know of/can find.
If I open the AMD Catalyst Control Center GUI, Crossfire shows as disabled. If I enable it I get told to reboot in order for the settings to take effect. When I do reboot and go back into AMD Catalyst Control Center, it's still disabled.
If I run,
Then I get the following output,
Multiple GPU chain for adapter 0, status: Crossfire is enabled
0. 02:00.0 AMD Mobility Radeon HD 5800 Series
1. 03:00.0 AMD Mobility Radeon HD 5800 Series
This was from following a tutorial I found about setting up a GPU chain. Whilst that seems to say that Crossfire is enabled (Though I think that might just mean the chain is capable of Crossfire rather than Crossfire itself being enabled), if I run
Then I get,
CrossFire is disabled on current device
CrossFire can work with P2P mapping through GART
Dongle Capabilities: support PASSTHROUGH |INTERLINK_SW_AFR | INTERLINK_AUTO_AFR | INTERLINK_BLACKING | INTERLINK_SUPERAA
Which says that Crossfire is disabled.
It should be doable I believe, as listing my candidates shows,
Master adapter: 0. 02:00.0 AMD Mobility Radeon HD 5800 Series
Candidates: 1. 03:00.0 AMD Mobility Radeon HD 5800 Series
I don't have any secondary displays connected to the laptop, just the built-in display.
From looking at the aticonfig help, I think I need to do something involving the following commands,
But I don't quite know what parameters I should be using with them.
Incase it's needed, I'm running the latest version of Debian.
