@prudhivisekhar - We can work this out together! There are multiple ways if I remember the Manjaro forum threads correctly, I myself use dual graphics w/ NVIDIA. I might be able to help solve your issues
No one should be avoiding Manjaro just because you couldn't figure out Nvidia probs
Are you facing the issue while trying to install the Manjaro system or are you facing the issue after it got installed?
What did you try in the Bumblebee page? And which bumblebee page are you talking about? is it this one Bumblebee - NVIDIA Optimus support for Linux! ?
