Zorin 16 keeps on locking the screen everytime

I've disabled automatic suspend, Dim screen when inactive, and set blank screen to never. What could be the problem?

Hi, and welcome to the forums.

Just to clarify, this happens when you close the lid on your laptop? Or is it at some time intervals when you walk away from the computer?

Also, are you using the Pro Core or Pro Lite version of ZorinOS? If you are on Core, which uses the Gnome desktop environment, then you can try following this thread:

Unable to Disable Screen Lock

Hello. In the Privacy section of the Settings menu, I have "Screen Lock" toggled to Off. I walk away, and after 15 minutes, the screen blanks, and then after 30 minutes, my computer puts itself to sleep as I have set it up to do. When I come back and tap a button on the keyboard to wake it back up, I would expect, since I have "Screen Lock" toggled off, that my computer would resume at the same screen that it was showing when I walked away. Instead, I am presented with a lock screen that requir…

In terminal, try

xset -s 0 0

If that does not work, try

xset -dpms

If that works, you can set it permanently by elevating to root

sudo -i

Navigate to /usr/share/x11/xorg.conf.d and create a new file. Name it
90-disable-dpms.conf
Copy and paste the below into it:

# Disable DPMS
Section "Extensions"
        Option "DPMS" "Disable"
EndSection
Section "ServerFlags"
        Option "BlankTime" "0"
EndSection
EOF

Save and close.

Am using Zorin 16 Pro, and it happens while am using my PC not necessarily when i close the lid. It is so annoying especially when am coding with Vscode

By this do you mean that it's happening more often while you're using VSCode, or it's just more annoying because you're in the middle of some work? Which leads to another interesting question: does this happen while you're using the computer?

Have you tried any of the suggestions from the previous posts?

This is also a little concerning. I can see the lockscreen being activated while watching a video or playing media like music. Due to a lack of mouse movement or keypresses.
But actively coding? Many of us know full well that is constant mouse clicks and movement and constant keypresses.

I would also add another suggestion: Thoroughly clean your keyboard. Blow any dust and debris out from under the keys - check for any sticking or gummy keys.
