Screen flickering

My laptop screen has been flickering making it difficult to work with it

Gday @kowalski21 ,
Can i ask which Zorin Pro Edition your referring too (Core or Lite)?
Can you please provide your machine Spec's.
Is this "Dual boot" or Zorin OS only?

I use to have a Lenovo laptop with that used to have this issue. Its actually an issue in the grub configuration. And this issue for me personally I had for any Linux distro I used not just Zorin OS.

in the terminal type
sudo nano /etc/default/grub

you are looking for a line that says this

replace it instead with this
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0"

then save the configuration file

type this into the terminal
sudo update-grub

make sure to reboot and the issue should be fixed. As mention this goes for any Linux distro you use as well. Not every distro uses the same update grub command though.
