I had to switch to Xubuntu 12.04 and 12.8 Catalyst drivers.
You could try just the 12.8 Catalyst drivers if you don't want to reinstall.
Topic: Unable to detect second GPU in Ubuntu.... tried a dummy plug (Read 2545 times)
What do you get with:
Code:
aticonfig --adapter=all --lsa
I tried
Quote
sudo aticonfig --adapter=all --initial -f
not sure the differences using initial and f but that did the trick, so basically what you posted.
Unfortunately now... I get GPU 1 failure within 2 secs of connecting to a pool.
Error -5: enqueueing kernel onto command queue
then gpu failure and disabling

Not sure whats going on.... 1 card works fine, yet the second I add another 7950 I get this readout from CGminer:
[2013-05-17 16:46:01] ADL found less devices than opencl!
[2013-05-17 16:46:01] There is possibly more than one display attached to a GPU
[2013-05-17 16:46:01] Use the gpu map feature to reliably map OpenCL to ADL
[2013-05-17 16:46:01] WARNING: Number of OpenCL and ADL devices did not match!
[2013-05-17 16:46:01] Hardware monitoring may NOT match up with devices!
and can't get any temp/speed monitoring. I've tried this dummy plug guide here http://blog.zorinaq.com/?e=11 yet still have no luck.... frustrating.
Any ideas?
I have export display=:0, gpu_max_alloc_percent =100, and gpu_sync_objects =1 before my cgminer input.
