Being new is no inhibition. It's very easy stuff.
You can open a terminal with the keyboard shortcut ctrl+alt+t
Now that it is open, enter in
sudo apt install inxi
Inxi is a great hardware reporting software. It will always come in handy, so recommend keeping it.
Once installed, ask what your graphics card identifiers are:
inxi -G
Now it wants you to edit a file. You can do this in terminal with:
sudo touch /usr/share/X11/xorg.conf.d/10-intel.conf
Or graphically. (GUI)
To use the GUI:
sudo -i
enter your password to elevate to Root. Now, launch yuor file manager:
thunar
It will launch in root. Hit the Up Arrow on the Toolbar, upper left side to the top Level Directory which is simply /
You will see the all the directories that tree your system here. Including /usr. So open that and follow the parh: /share/X11/ until you see the folder named xorg.conf.d which can be opened with double click.
Right click an open area and choose to create a new document.
