Multi monitor setup Optimus/Bumblebee with Cinnamon Desktop Environment about bumblebee

[srosano]

Fixed this by using the modesetting driver instead of "intel" as I didn't have the intel drivers installed - this is as recommended by the Debian wiki. However it is personal preference what drivers you choose to use - note to use intel drivers they must be installed.

You will also need to do the following as per the multi-monitor bumblebee wiki:
xrandr --listproviders (don't need to do this one but makes more sense to work out which monitors are in which order)
xrandr --setprovideroutputsource 1 0
xrandr --output eDP-1-1 --mode 1920x1080 --primary --preferred --output HDMI-0 --right-of eDP-1-1

You will also need to find the ModulePath "/usr/lib/x86_64-linux-gnu/" to libGL.so directory (not sure if directory has changed since new updates and thus hasn't been updated in the bumblebee multi-monitor wiki).
