Nvidia Laptop users using NVSlimmer beware - Hell Corner

So this fine day I woke up to my laptop's second GPU being recognized as not working 3D Video Card , everything surrounding the case seemed like it went busted , it wouldn't update driver , attempting to remove the driver worked , but re-installing it using official stock package failed , attempting to uninstalling it via DDU seemed useless since even DDU wouldn't recognize it as an NVIDIA GPU .

So to cut it short after further tinkering it turns out that since I have been using NVSlimmer for a while now (a bloatware remover for NVIDIA drivers) I was accustomed to using it in its most default settings (Core Display Driver / Install Core / PhysX) so I noticed that there was an option I always overlooked which was "Optimus Support" , I added it to the defaults and to my surprise the driver managed to install smoothly and GPU went back online while the stock package wouldn't .

So I've always known that "Optimus" technology was essential for laptops to allow "Dual GPU Setups" where if absent it may be required to turn off the Intel GPU from desktop's motherboard bios to allow the NVIDIA to enable . But I never even bothered paying attention to what NVSlimmer does I just had it do what it do in defaults for well over a year of use now .

What I still can't find an answer to yet is why did windows allow me for this whole time to work in "Dual GPU Setup" in absence of "Optimus" but yet waking up this fine day to "Hey , this doesn't seem right !" ...

So anyways this is a heads up solution if it ever came up to this to any of you .

Cheers

Good day.

Thanks for the information. I also use nvSlimmer, but I usually tick some more options than defaults (which are rather minimalistic in my opinion).
