[Trisquel-users] Re : How to increase the font of the virtual console

[lcerf]

The "virtual console" (pts, not tty) controls the size of the font it shows.  
For instance, Ctrl++ (that is the "+" key pressed while pressing the "Ctrl"  
key) in the GNOME Terminal (by default in Trisquel) increases the size of its  
font. To change it more permanently, see the preferences of the profile in  
the "Edit" menu.

If you are actually talking about a "real" console (tty), then use the  
'setfont' command with the -h option. The fonts to choose from are in  
/usr/share/consolefonts (and you can install some more).
