Hello,
 
I have been on the web site: https://fedoraproject.org/wiki/Bumblebee
However,
lspci |grep VGA
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
 
The /sys/kernel/debug/vgaswitcheroo/switch file does not exist.
 
Hence, it seems that I do not have an optimus notebook computer

I will have to disagree with you, what is the output of 

lspci | egrep 'VGA|3D'
