I have Lenovo Y540 which has an option to turn off intel gpu (Optimus) and 90% of the times I turn off Optimus and use the Nvidia GPU because of the performance difference but I switch on the Optimus when I need the battery life, so here's the catch:

when Optimus is switched on I get a black screen so I was trying to add a grub option to turn off or blacklist Nvidia GPU when Optimus is turned on but nothing works I still get a black screen, please help. I don't want to use windows on battery!

tried: nvidia.modeset=0 blacklist nvidia module_blacklist=nvidia

Thank you

Ok so its fixed In summary you need driver 460 or higher without anything like prime select. Set the laptop on "Optimus on" then install nvidia driver without prime-select and in this scenario everything will be fine, you can easily switch them from bios.
