[SOLVED] Cinnamon screensaver fails to update screen upon wake-up

I am getting a strange intermittent issue with Cinnamon-screensaver in that when opening the lid of my laptop it will display my desktop , with mouse pointer moving, but not the dimmed screen and login box you’d expect, and no other interactions. This occurs 90% of the time now. If I type my password in and enter, regardless, then everything comes to life, and I see the apps I had open previously.

Fix for my problem:
add this to my kernel parameters: intel_pstate=disable
like this:

sudo nano /etc/default/grub
changed to GRUB_CMDLINE_LINUX_DEFAULT="quiet irqpoll intel_pstate=disable loglevel=3 "
ctrl-x, y
sudo grub-mkconfig -o /boot/grub/grub.cfg

Then reboot, and test lid close , pause, reopen. Lo and behold, a lock screen!
