I tried following this Wiki guide about it:
But it clearly says that you have to disble/uninstall Bumblebee to be able to run it. I've tried the later, uninstalling bumblebee and all related packages. However, when I install optmus-manager and restart the system, it completely freezes. I had to reinstall the whole OS again (not a very big deal since I just switched to Manjaro a couple hours ago) so here I am in the same place.
Also, this may be important: in Manjaro Settings Manager I've got video-hybrid-intel-nvidia-bumblebee installed for my card. Is that the correct driver I need to use? I tried switching to video-nvidia but with that one I wasn't even able to log in to my session because I was getting a black screen after booting (had to reinstall the first one through a TTY).
Any help is appreciated!
