Tutorials & Guides

If you are installing Zorin OS on a dell laptop, you might need to boot into graphics safe installer or you will experience severe lag and lack of mouse/keyboard support. Once installed you will also have too disable PSR otherwise you will get the same lag and the OS will be unusable. The following is from gemini which helped fix the problem:
Fix 1: Disable Intel Panel Self Refresh (PSR)

Intel PSR attempts to save power by idling the screen refresh when the image is static, but on Linux, it frequently gets confused, causing severe UI lag, mouse freezing, or stuttering. [1, 2]

  1. Open your terminal and open the GRUB bootloader configuration file:

bash

sudo nano /etc/default/grub

Use code with caution.

  1. Find the line that looks like this:

text

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Use code with caution.

  1. Change it to append i915.enable_psr=0 inside the quotes:

text

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0"

Use code with caution.

  1. Save and exit (Ctrl + O, Enter, then Ctrl + X).
  2. Update your system to register the changes:

bash

sudo update-grub

Use code with caution.

  1. Reboot your computer. [1]

Welcome to the Forum!

I have changed the Thread Category to Tutorials & Guides because this is not a Help Request. So, it fits better in the Guide Section.
