I ran optirun glxgears command after installing Bumblebee and Primus. And it run without a problem. At the end of the documentation they mentioned a steps related to adding some more script and editing some file to prevent screen tearing or something like that and I followed that steps too.
After restarting when I run theit gives me below error in terminal as the image attached to this post shows.

What version of Parrot are you running? (include version (e.g. 4.6), edition(e.g. Home//KDE/OVA, etc.), and architecture (currently we only support amd64)
64 BIT SYSTEM
Configured to multiboot with other systems? (yes / no)
Yes. with windows 10. But I think that had nothing to do with my problem. Since problem started after following last steps mentioned in the official documentation which I linked at the beginning of this post.
Actually I think that nvidia+Dell doesn’t work properly on Linux, not sure why !
I ran into same problem today, that I ended up with broken nvidia driver and I couldnt avail it. I did everything from documentation again and couldn’t even do the test runs(Because of broken package I guess). So basically getting nowhere, I guess from constant re-installation, some packages must have got busted.
So if that happens to you even after reinstalling the drivers(Using apt command as shown in documentation) and removing files you have created from documentation. I suggest you to do what I did.
Error was this with broken nvidia-driver:
______$ lspci -v
01:00.0 3D controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Ti Mobile] (rev ff) (prog-if ff)
!!! Unknown header type 7f
Kernel modules: nvidia
And this is my optirun error:

Make sure you have nothing installed related to nvidia(from apt or anything that case) before installing downloadednvidia.run file . If you have then you must delete/remove them. undo everything from documentation as well… except removing this file /etc/modprobe.d/blacklist-nouveau.conf do not delete it because its necessary in future.
Then I logout of the system and went to login screen pressed alt+ctrl+f1 .
Login again as user. and stopped lightdm service that is necessary for installation using sudo service lightdm stop
Next thing I did was installing the driver as root.
When the installation was success, reboot the system. Now see if the driver is there using lspci -v , if it is then uninstall the driver and follow the documentation again and Now doing the test run, it works fine.
