Hi
I have 2 mining rigs, one which is just an older computer I had that I stuck two new 7950s in and installed Xubuntu on a usb drive, setting it all up was relatively straightforward for me, and it's now happily mining.
My second rig is totally new, has a low end mobo and celeron cpu, with 4x7970s connected through riser cables. I have had a lot of problems setting this up. First of all, I tried many times to get it working on Xubuntu with lots of different sets of drivers and doing things differently. Currently, the problem is, xorg hangs/crashed when more than one card is plugged in, and there is no real information as to what causes it;
Xorg log:

I installed windows 7 on a spare HD I had, got all the drivers for everything from the mobo manufacturer, got the latest amd drivers, tried to mind - but it didn't work. Every time, any miner I use says no graphics cards detected, and it boils down to opencl giving "Error: -1 getting device ID". So if I do cgminer -n, it will list opencl vendor as AMD, it will give the right APP SDK version (2.8) - everything seems fine, but then it reports that error: -1 getting device IDs. All my cards come up fine in device manager and in the catalyst control panel. I have tried 13.4 and 12.10 drivers, uninstalling everything and reinstalling them and the app sdk in between attempts. I really thought that windows would be much easier, but apparently not so.
I have both windows and xubuntu installed on that machine and can easily swap between booting either, so if anyone has any advice relating to any OS, please give it to me :P I want to try the most things in the hopes of getting something working. I've been trying to get it working for weeks now, I'm just really stumped at why this is so difficult and why I'm having so many problems.
Thanks
