I had nvidia gtx 1060 and kabylake igpu working fine with bumblebee until the the cuda driver rollback or something and ended up with nvidia-384 which started showing nvidia-persistance demon issues and to fix it I almost reinstalled ubuntu 16.04.3 + intel microcode + nvidia 384/375. None of the combination generated successful prime-select(along with prime select I have to work with secure boot too).
Is there any way it can be fixed?
All I need is to have nvidia for cuda(tensorflow/keras) and igpu for everything else
I cant switch between nvidia and intel using prime. Choosing intel kills nvidia persistence demon and stucks until forced reboot. But it seems like enabling secure boot I can use intel using prime .yet to switch back to nvidia I have to disable secure boot which is annoying and I want to configure bumblebee. I can switch between nvidia/intel by adding and removing nogpumanager too.
I hope it could help. I installed all firmware patches before intel/nviidia installation. I installed ubuntu having secure boot disabled
Ok, this clarifies it a bit. I presume by ‘firmware patches’, you’re talking of an uefi aka bios update? Telling by the symptoms you might have run into this:

Please check if the workaround, using kernel parameters
acpi_osi=! acpi_osi=“Windows 2009”
works for you. Please run acpidump and attach the output file to your post so I can have a look at it.
Hi,
Thanks man. That works. but yet I am getting the same nvidia persistence demon error. It creates error pop ups too when i am logged in. can you explain what the demon do and how this error can be fixed?
