Newbie to linux mining.
i have 5 sapphire 7950 setup last night to mine ltc in xubuntu 12.04. After 6 hours mining, I believe one gpu gets crashed and xubuntu never gets recovered from the crash since now I can only see 4 graphic cards using command
sudo aticonfig --adapter=all --odgt
I also noticed that my xubuntu desktop is abnormal, since the color in the background looks like its in the middle of a crash.
Anyone can help me diagnose the issue??
Make sure all your physical connections are solid? PCIe risers, PSU plugs, etc? Are the fans spinning?
Do a "lspci" command to see how many GPUs the system can see. Each card should show up as a VGA device, and also a separate audio device. Do you see 4 or 5 GPUs there?
If it's seen by lspci, but not aticonfig, you'll have to delete your xorg.conf and redo the config. "sudo aticonfig --adapter=all --initial --force". Then reboot, and see what you can see then.
If you still can't see it, try upgrading to the 13.11 beta 9.5 drivers that just came out like 2 days ago, and do all the steps above. Those drivers seem to give me the least hassle.
