While I was playing with Cinnamon settings I set the font size to 990 from the font icon available in cinnamon settings. Now I can't use any applications because of the font. It garbles the whole screen. I cannot redo it because when I somehow manage to open Cinnamon settings, I can't see the font icon, because of the font size, even if I maximize that window. I can see up to icon themes, that's it. Now what to do, Is there any way of setting things to normal? I tried setting Cinnamon settings to default but did not work. Now what to do? Is it possible from a terminal?
Open a terminal and enter:
gsettings set org.gnome.desktop.interface font-name 'Sans 10'
You may have to go to Cinnamon Settings after this and reset the font as well.
