Conky

Conky

Conky is een desktop applet die oa een aantal systeem monitors kan tonen. De configuratie gaat via een vrij eenvoudig te begrijpen tekstbestand.
Ik gebruik daar een paar speciale fonts voor, om symbolen te tonen. Zoek daarvoor op Google naar Conky fonts. http://youfont.com is ook een goede plaats om fonts te zoeken.
Voor de installatie, zie http://www.ubuntumini.com/2008/12/install-ttf-font-microsoft-core-fonts....
$ unzip ~/downloads/Conky\ Fonts.zip
$ cp ~/downloads/Conky\ Fonts/*.zip ~/.fonts
$ sudo fc-cache -f -v
Met fc-cache wordt de cache met geïnstalleerde lettertypen opnieuw aangemaakt. De Conky fonts zijn lokaal geïnstalleerd in ~/.fonts.

Daarna moet Conky geconfigureerd worden. Dit is de inhoud van mijn ~/.conkyrc:
