When I typed "export DISPLAY=:0" it didn't display anything. Then I try aticonfig related command.. these's what I got:
username@pcname / $ aticonfig --odgc --adapter=all
No layout section was found in the file: '/etc/X11/xorg.conf'.
Please run 'aticonfig --initial' first or modify your configuration file manually and run aticonfig again.
aticonfig: parsing the command-line failed.
username@pcname / $ aticonfig --initial
Uninitialised file found, configuring.
Saving back-up to /etc/X11/xorg.conf.original-0

I think that card has 2 GPUs each.
So with 2 cards, cgminer would have to have detected 4 GPU's if that is correct?
My GPU settings (press 'G') didn't right. It only showed 2 GPUs not 4.
Yeah I'm not too sure what number of GPU's cgminer should show.
I think 4 is correct but someone else who has those cards will have to say for sure.
Edit: also you should mention which linux/version you are using and which ATI drivers you installed (the filename you got from ATI/AMD)
I used Peppermint OS
64bit on my two PCs. When I try to update one OS to Ubuntu 11.10 by it's update manager it crash (can't opened OS after that). The other one which didn't do the update is working without any problem. These problem happened on the reinstalled linux(peppermint) pc and it didn't update to Ubuntu 11.10.
Thanks for your helped!
Unless you've found a security update in 11.10 that you think you need, there is no real need to update to 11.10
If you read the script in my sig ...
You need sudo in front of all the aticonfig commands.
(my sig now points to the latest version of the script - I created a git to store just it on it's own)
To ensure proper access to the cards you need to be sure the GUI is running and that your process has access to it.
If you are running a terminal on the screen as the same user that started x then it should be fine.
If you ssh into the machine, then ensure you ssh to the same user as the GUI and then "export DISPLAY=:0"
To check that you can see the cards:
sudo aticonfig --lsa
Then to create the xorg.conf:
sudo aticonfig --adapter=all --initial
I'd suggest you reboot after this (or at the least - stop and restart x)
