How can I turn off font-antialiasing only for gnome-terminal, but not for other applications?
Solution 1:
Not sure if this actually works, but you could try to use .Xdefaults to configure this. Make a file named .Xdefaults in your home dir. Put in the following:
Xft*antialias: false
Effects everything!!! Just find the right name, and it should work.
Solution 2:
Why not try using a decent anti-aliased TrueType monotype font, a la terminus? It looks great at nearly any size. On Ubuntu/Debian the package is named xfonts-terminus.
