Title: Setting fan speed in Ubuntu 12.04 Post by: walruscode on March 12, 2013, 09:44:46 PM Hello. I have a multi-card mining rig with a 7970 (reference) and a 5870 (dual-fan Gigabyte) that I am trying to switch over to Ubuntu. I get good hashing speeds with cgminer for my 7970 (~625KH/s), but cgminer doesn't seem to recognize my 5870. Here is the error I encounter:
Code: ADL found more devices than opencl! It would be nice to at least get the 5870 working with cgminer, even though I don't intend to use cgminer to mine on the 5870. I'm now having trouble with AMDOverdriveCtrl. I need to set the clocks/fan speed of my 5870 using aticonfig (clocks) and AMDOverdriveCtrl (fan speed) because reaper will not do this for me. While AMDOverdriveCtrl recognizes both my 7970 and my 5870, it will only use the adapter for my 7970. Here is the output of "AMDOverdriveCtrl -h": Code: $ AMDOverdriveCtrl -h Code: $ AMDOverdriveCtrl -i 6 EDIT: In addition, Reaper does not recognize my 5870.

My 5870 just got back from warranty work today, so the bios should be set to factory settings.Title: Re: Setting fan speed in Ubuntu 12.04 Post by: -ck on March 13, 2013, 05:10:38 AM Did you do a proper reconfigure of xorg.conf?
Code: sudo aticonfig --adapter=all -f --initial Did you export your display variable after xorg is started before mining? Code: export DISPLAY=:0 Title: Re: Setting fan speed in Ubuntu 12.04 Post by: walruscode on March 13, 2013, 05:19:45 AM Did you do a proper reconfigure of xorg.conf? I could have sworn I did the first command, but I went ahead and did it again and rebooted. I was forgetting to export the display variable; after doing so, everything (except for AMDOverdriveCtrl) is working wonderfully! Thank you!Code: sudo aticonfig --adapter=all -f --initial Did you export your display variable after xorg is started before mining?

Never been keen on software solutions.
