Gnome font size

My personal hint for this one: just log out and log back in and your old font size will be back or so. Just don’t start editing your font config in the gnome-control-center (Desktop >Theme Selector > Use custom font) because this will screw up everything later on and change only the font sizes of some gnome apps while it will leave the panels, mozilla and most everything you really want back untouched.

And by the way change your X-resolution with CTRL-ALT-+/- I had forgotten the command because it’s been ages I used it.
