Guys is there any way to change a particular file in the / usr directory?
I need to comment on the “modifier_map Mod3 {Scroll_Lock};” in the file “/ usr / share / X11 / xkb / symbols / br”, but I can’t find the directory read only.
Which is why I need to make this change and the lag that is occurring when pressing hotkeys on the keyboard “Increase volume, billiard, play / pouse … etc” the gnome shell interface crashes and after a few seconds comes back. The problem only occurs using xorg server.
