To be clear, nvidia users need to enable both foldingathome.service and foldingathome-nvidia.service.

@keithy can you get the full log of foldingathome-nvidia with journalctl? And what does foldingathome say? There's really no reason why even CPU folding wouldn't work after these changes.

@Buddlespit: don't know what to say, it works on both my 1050 and my 1080Ti, well enjoy giving root access to your whole system to some closed proprietary code then

@alucryd: No change with 7.6.9-4. Neither CPU nor GPU fold until I restart foldingathome.service

This is the status of the foldingathome-nvidia service in case it sheds some light!

To be clear, nvidia users need to enable both foldingathome.service and foldingathome-nvidia.service.

@keithy: the latest foldingathome-nvidia service consistently works for me on my desktop

@Buddlespit: Did you read the latest install notes and enable foldingathome-nvidia? Did you try restarting the service like others do?

@alucryd:

Sorry, 7.6.9-3 is a backward step for me.

Now neither CPU nor GPU fold until I restart foldingathome.service.

After restart only CPU folds :(

Edit: GPU does fold as well after service restart - it was just trying to download another WU

@xuanruiqi: Awesome, we're getting there.

@Pezlu @keithy: I can't find confirmation in the systemd documentation, but I believe ReadWritePaths is evaluated before ExecStartPre, so the first time those paths don't exist so systemd doesn't give you access to them.

I've added a new service named foldingathome-nvidia.service, if you enable both this one and foldingathome.service, the nvidia service should run first, and by the time foldingathome starts, the paths should be there. Please let me know how it goes.

@alucryd: OK, my GPU is working again...

@alucryd: I just updated to 7.6.9-2 and the client behaviour didn't change, I still have to restart the service. I'm on a desktop.
