Ubuntu 22.04 driver problems

The product code on behind is P751DM2-G . Please tell if this enough or I have to add something else ?

That’s just the model code of your notebook, not the panel. Should look like
“AUO B089AW01”

Maybe on of these…

You just opened the bottom cover. The top with the panel. The sticker is on the back of the panel. Rather don’t do it.

Oh I got it. Probably I’ll pass on doing it… this is enough though. Many thanks to you!! That is a great success after a month !!
