Hello, frequently when I use my laptop, the screen becomes gray (shades of gray, the bottom is lighter than the top).
In the last few days I have been writing down what I spank when it happens to me. Each time I was connected on the internet. On firefox, on sites or in jupyter notebook hosted locally.
When I'm at school, I'm not connected to the internet, and that never happens to me.
I'm on ubuntu mate 22.04 LTS
I have an HP elitebook 820 laptop
if you want more information, you can ask me
thanks for reading, I'm sorry, my English is not perfect, ask me if you didn't understand something.
