I've got a machine running Kubuntu 18.04 64 bit. When I log out and log
in or press ctrl alt backspace; beginning at the login screen the text
is much smaller. The first time this happened, I reset the text to make
everything the size I wanted. When I rebooted the machine, the text was
too big, so I made it smaller. It wasn't doing this when I first
installed the OS on this dinosaur. Any idea what happened, or more
importantly, how I fix it?
