A few years back, Ubuntu started to play around with different fonts and different settings for antialiasing and hinting, making the desktop look boldish, and fonts bigger than they should be. This was not too much of a problem because old versions of Gnome (2.x) had a great tool for changing the font settings, however, since Unity interface came along, these options disappeared from GUI. Nowdays, Gnome3 is getting popular and since Unity uses the same settings manager, we’re left out of options.
Although there’s no graphical tool anymore to set this in an easy way, there’s an interface tool called ‘gsettings’ which can be used to accomplish the same goal. Basically, everything that Gnome team decided that is not ‘simple enough for users’ is removed from GUI tools. And there goes our favorite font configuration GUI :(
To get back that fine, slick look of your fonts that don’t make you feel like a half blind person, open up your terminal and try out these commands:
gsettings set org.gnome.settings-daemon.plugins.xsettings hinting 'medium' gsettings set org.gnome.settings-daemon.plugins.xsettings antialiasing 'grayscale' gsettings set org.gnome.desktop.interface document-font-name 'Arial 10' gsettings set org.gnome.desktop.interface font-name 'Arial 10' gsettings set org.gnome.desktop.interface monospace-font-name 'Monospace 10'
Hope your desktop looks sane again :)
