I am worried I may have bricked my computer. I altered one character in the /user/share/X11/xkb/symbols/keypad to add a ] where there shouldn't be. The result is that all keyboard input does not work on my computer, even the on screen keyboard. The only thing I can do is login to guest user by clicking because no typing is necessary. How can I change this file from guest user using only copy and paste and guest permissions in terminal?
I have copied a whole list of commands into a txt file and have been copying and pasting them in to terminal, but I don't have the proper permissions.
What I wanted to do was "sudo cp -f" the correct version of the keypad xkb file but even with the sudo password I cannot do that from guest.
