When I booted my laptop today, something strange happened. It seams as if the font size of the System is changed to a extremely small one.
Titles of windows, the browser bar in Firefox, Terminal, just every thing is affected by this. I almost can't read anything anymore (fortunately the websites are displayed as usual).
I haven't changed any settings, but had some updates yesterday (just the normal Ubuntu update stuff).
Any idea what happened and how I can get my System back to normal?
