[Linux Mint] Unable to add GPU slot

[bobmanuk]

Good Afternoon All,

I recently installed Linux Mint 18 Cinnamon on my Lenovo Ideapad 700 (i7 cpu with GTX 950m)

I have installed the client and control apps with no problem and it has automatically detected the CPU and started folding on it.

I have installed the Nvidia drivers for linux and it detects the GPU ok, lspci also detects the GPU correctly.

But as i try to add the GPU slot (everything is -1) it tells me "No GPUs Found"

trying to do FAHClient --lspci gives the following

Code: Select all

Lenovo /usr/bin $ ./FAHClient --lspci

any thoughts on what i should do?

also, apologies if i posted this in the wrong place

Cheers,

Bob

What do you mean with -1 (for GPU)? OpenCL index ? You might could try to fresh install FAH and let the installer figure out the right config.

Is the nV the only GPU or is there also an iGPU involved (via CPU)?

look here if any differences to the way you installed viewtopic.php?f=80&t=27040
Make sure to blacklist other open source drivers

It's always important to install the GPU drivers prior to installing the FAH software. Until the drivers are installed the o/s knows very little about the GPU and it's OpenCL support thus the folding software doesn't receive the information it requires.

I would set the CPU slot to Finish and then re-install the folding software.

Also, the following link will take you to a very good guide for installing the Nvidia driver:

-1 is whats listed as a default when trying to add a slot in the fahcontrol app, from what i understand from windows -1 is what is entered to allow the control app to locate the GPU itself

there is an integrated GPU, intel

its an "optimus" laptop where the intel display is used for basic display tasks and it should switch to the nvidia display when running more gpu intensive apps such as games, at least thats what happens in windows, on linux its more involved but not what this thread is about.

I will remove the fahclient and reinstall no problem, i will let you know once ive tried it.

I tried removing all FAH software and rebooting, i have just reinstalled everything again but it still wont detect the gpu.

I have the nvidia drivers already installed, if i do nvidia-smi from the terminal it gives me information about the gpu

EDIT

Also from the Nidia X server settings panel, it shows as NVIDIA (performance) is selected as the main GPU (the other option is INTEL (power saving mode))

Could you please post the folding client log? Especially the top 100 lines or so. - that might shed some more light on things.
Also check that there isn't a GPU = false flag set in the advanced configuration.

GPUs.txt contains a line:
0x10de:0x139a:2:4:GM107 [GeForce GTX 950M]
which indicates that your GPU is supported provided you've properly installed/activated the drivers as supported by NVidia. Drivers from other sources may or may not support all the features needed by FAH.

If the drivers do NOT support the necessary features, the most common error message is the one you're reporting.

There is NO support for the Intel iGPU ... GPUs from NVidia or AMD/ATI are supported.

Optimus devices are known to be problematic when folding. I don't recall the details, but there are several threads here about the issue. Also don't know if they ever found a folding solution, but you can search the forum for the answer.

I had to switch back to my windows SSD for a project I'm working on so for now I'll just stick to folding on windows, thanks for the help
