First error is that by default the shebang at /usr/bin/FAHControl is using python which is by defaut pointing (to Fedora 31 system and most other systems) to python3. As a result I am getting:

$ FAHControl
File "/usr/bin/FAHControl", line 57
if sock.recv(1024).strip() == 'OK': print 'Ok'
^
SyntaxError: invalid syntax

Manually editing the file and changing:

Code: Select all

- #!/usr/bin/python
+ #!/usr/bin/python2

seems to be starting although I am getting this error from the command-line:

Code: Select all

$ FAHControl

Another problem I have is that the GUI opens, when I go to the System Info tab, at the System Section I see:

Code: Select all

GPUs:1
GPU 0: Bus:1 Slot:0 Func:0 NVIDIA:7 GPI104 [GeForce GTX 1070] 6463
CUDA Device 0 Platform: 0 Device:0 Bus:1 Slot:0 Compute:6.1 Driver:10.2
OpenCL: Not detected: clGetDeviceIDs() return -1

From the Logs tab I see:

Code: Select all

13:39:11:ERROR:WU00:FS00:Failed to start core: OpenCL device matching slot 0 not found, try setting 'opencl-index' manually

I have installed:

Code: Select all

sudo dnf install mesa-libOpenCL clinfo ocl-icd-devel

Please help

To get OpenCL ready for FAH try:
sudo apt-get install ocl-icd-libopencl1
sudo apt-get install ocl-icd-opencl-dev

Hi,
I just setup a GTX 1070 system on Fedora 31 with NVIDIA driver 440.64 and it's working fine.

Your 2nd error looks to simply be that the client selected the wrong GPU. Your log shows that GPU 0 is the GTX 1070, so edit /etc/fahclient/config.xml and look for the GPU slot and change the index to 0. Should look something like:

Code: Select all

  <slot id='0' type='GPU'>
    <client-type v='advanced'/>
    <gpu-index v='0'/>
    <verbosity v='5'/>
  </slot>

Then, restart the client.

good luck!

Just leave the verbosity at the default value of 3, higher values do not currently provide any useful information in the log file.
