These are screenshot of the screens
I have been using zorin os from last 2 years. Now recently I had experienced these problems. Sometimes screen just works fine and sometimes the screen starts flickering. I have double monitor setup and I'm experiencing this issue in both screens.
To solve this issue I have reinstalled the zorin os on my laptop but the issue is still happening.
Below is the full report of my laptop
