I found a solution on this site: https://joshtronic.com/2017/07/26/hide-title-bars-in-gnome-shell/
Copy this code from site and paste in ~/.config/gtk-3.0/gtk.css (open this with gedit or nano (I used gedit)).
After that save and you can close that windows (gedit) and I prefer you open new terminal. After you done that part, in shell (terminal) paste this code:
gsettings set org.gnome.Terminal.Legacy.Settings headerbar "@mb false"
(this command is on that site too), after that do ALT + F2 and put latter "r" in command line, click ENTER. This fixed my problem.
You just need to open new terminal and see if that worked.
^ If this doesnt work than open terminal and paste those commands:
sudo apt install gnome-shell-extension-pixelsaver
gnome-extensions enable [email protected]
gsettings set org.gnome.Terminal.Legacy.Settings headerbar false
-and after that go to ~/.config/gtk-3.0/gtk.css if code you paste that disapear copy it and paste it again. Again, run command line:
gsettings set org.gnome.Terminal.Legacy.Settings headerbar "@mb false"
And after that do ALT+F2 and in command line put latter r and click ENTER.
You just need to open new terminal and see if that worked.
I hope this helped some. Nice day to all of you guys! :)
