SETI MB CUDA for Linux
sunu:
What are you trying to do with X? Do you have 1 or 2 monitors? Your xorg.conf is like you want to run two X screens in one X server, while your xorg.0.log says that you have only one monitor connected and then it proceeds to unload the nvidia kernel module :-\
(II) UnloadModule: "nvidia"
Running
lsmod | grep nvidia
what does it give you?
Also, What does
ls /dev/nv*
give you?
I edited your xorg.conf commenting out the double device, screen and monitor sections and changing some other minor stuff.
I see at mandriva's site that they have released 2011 RC1. Why don't you try something newer?

Hi Sunu
A quick explanation and time line,
Built machine and installed OS and BOINC - latest available updates applied - Started machine with only one monitor connected - When BOINC running noticed only one GPU was being used - searched web for answers - one answer was to make 2nd card think it had a monitor connected - Even with a 2nd monitor physically connected 2nd card still not crunching - tried several more of the "fixes" found on the web - still no joy - checked hardware by installing different OS - AOK - help sought from Lunatics.
SETI is down atm and the box is out of work, I'll try your xorg file when the project is back up and report back then.
I find this really intriguing, BOINC recognises both cards and runs 2 instances of the crunching app - it's just that both run on the card in PCIE slot 1 - Using one card only, in either slot it, works properly - Even setting the BIOS to boot using PCIE slot 2 makes no difference. What I haven't done is try a different project to see if that works, I'll try that tonight.
One positive thing to come out of this, my vi skills have definitely improved :)
Thanks for your help
T.A.

This is/was for windows. Doesn't matter in linux. Unless you want to run multiple X screens or servers.

You still owe me many things:
- A proper ps... when seti is running (supposedly or not) in two GPUs.
- A proper nvidia-smi output with and without seti running, current and new xorg.conf.
- Those two above lsmod... and ls... with your current and new xorg.conf.
- A xorg.0.log with the new xorg.conf.

No - both were installed

I don't - I just happened to be root in the console when I ran those commands
--- Quote ---2) There is no "--device x" flag on the running app. Is this because of small terminal window? Make it bigger and recheck.

Pardon my ignorance but where should that line be ?

That's all that came up. (Is this a clue to the problem ?)

It shows only one instance running.

Maximize your terminal window and rerun it. Alternatively rerun it with > ps.txt at the end and post the file.

No, it is a clue that you need to update kernel, driver, distro, everything ;D
Also, how is boinc installed? From repositories or from berkeley? In root or your home directory? I always keep everything boinc/seti related in my home directory and far away from root.
