Does this help to fix the glitch ?

Looks like you are running optimus technology; therefore, you might want to
look at [0] configuring Bumblebee on your laptop if you will like to use
your NVIDIA Graphic card.

Of you can append the following lines to the kernel argument
nouveau.modeset=0 rd.driver.blacklist=nouveau

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

lspci | egrep 'VGA|3D'

Think the document need to be updated, my 2012 Optimus laptop has what is
in the document but my 2015 laptop doesn't, so were you able boot without
the locks?

Nvidia), you will still have full access to the Intel driver; therefore
your boot will not lock up.
