2 X 5870 problem

[smracer]

Hello all!

I am new to bitcoin mining and I bought a 890FXA-GD70, 2X5870's, sempron cpu, 4gb ram, USB Drive.

I am running Xubuntu and cgminer.

When I start it up I type ./cgminer -n and it says 1 GPU Detected.

I then run ./cgminer and get 410mh/s

Then I quit cgminer and type export DISLPAY=:0

Then when I type ./cgminer -n it says 2 GPU Detected.

Then I run cgminer and each GPU gets 200mh/s and GPU1 is 20c cooler than GPU0

It seems to me that GPU1 isn't really running even though it shows it is in cgminer.

any ideas?

I have done aticonfig --adapter=all --initial -f

crossfire cable not installed.

thank you.

I reinstalled 11.04 and it worked fine now.

thanks!
