[Request] thinkfan nv_thermal compatibility

[Nitrooo]

I use thinkfan on my ThinkPad. You can configure it to read the NVIDIA GPU temperature using the nv_thermal entry in its config file. The problem is that optimus-manager doesn't work properly with that configuration because it can't unload the nvidia module when thinkfan is running in that mode. I would need two scripts like /etc/optimus-manager/nvidia-enable.sh and /etc/optimus-manager/nvidia-disable.sh, but prior to disabling and after enabling the nvidia module (switch from/to nvidia AND hybrid), to reload thinkfan with the proper configuration (with or without the nv_thermal entry).

Can you add such additional scripts? What could I do otherwise?

Hello @Nitrooo .

While we would love to see a feature that would integrate thinkfan with optimus-manager but I think this would be better suited for thinkfan to deal with, and not "hold" the module making the unload operation to fail, the same way there is a issue on that repo to deal with the fact hosts can miss one GPU that is being pci disabled for power

• Failed to initialize NVML driver. If gpu is disabled

Also, this case is really a corner-case for optimus-manager and it will require someone with a Thinkpad laptop to develop it so, while this community is open for pull requests that would implement those nvidia module load/unload hooks, we'll keep this case closed until someone comes with a PR to implement this.

We suggest you to also open a case on thinkfan repo for them to create a mechanism that nv_thermal will not hold module unload and deal with the fact that this module might be missing, specially on laptop environments.

Have a nice week ahead.
