[2013-05-15 22:53:05] ADL found less devices than opencl!
[2013-05-15 22:53:05] There is possibly more than one display attached to a GPU
[2013-05-15 22:53:05] Use the gpu map feature to reliably map OpenCL to ADL
[2013-05-15 22:53:05] WARNING: Number of OpenCL and ADL devices did not match!
[2013-05-15 22:53:05] Hardware monitoring may NOT match up with devices!
Check this thread and see if its the same or similar problem.
https://bitcointalksearch.org/topic/m.1857068Thank you for the link. I came across this before but it isn't the problem. I tried it with real screens attached (and powered on) and that didn't change anything. The issue is not getting a nagging message, it's ADL not working with that "Failed to ADL_Adapter_ID_Get. Error -1" message.
...
The only thing I want to keep is Linux, I really don't want to switch to windows on these boxes if I can avoid it. What kind of Linux, I don't really care as long as I get the temperature, fanspeed and gpu settings to work.
If there is any more data I can deliver, please let me know.
ADL requires correct X access.
Here's something to try see if X access is correct:
DISPLAY=:0 xlsfonts(of course you need xlsfonts installed - use some other X program if you don't - xlsfonts doesn't open a window - just reports information)
Maybe gpu map is your solution (as it says to use)
Otherwise ... at a guess ... ADL version?
Edit: oh forgot, also on the 2 rig machine, you need to have done (in case you missed it)
sudo aticonfig --adapter=all -f --initial as per GPU-README
Thank you Kano.
DISPLAY=:0 xlsfonts did not work at first as the package was missing as you said. "aptitude install x11-utils" took care of that. Now the result is this:
# DISPLAY=:0 xlsfonts
xlsfonts: unable to open display ':0'
So there seems to be something not working right here. Any ideas on how to fix this?
I'm certain I did sudo aticonfig --adapter=all -f --initial (tried with one card, then the second) after each install, but just to be sure I did it again and rebooted the machine, with the same results still.
