Applications which use the legacy X11 core fonts system for font access and rendering do not have antialiasing features. Only applications which use the Xft client side font access library along with fontconfig benefit from antialiasing and subpixel rendering.

In >gnome-font-properites I have to set the subpixel order to "VRGB" (which >is rather strange since the article you pointed me at says that there >are no LCD displays with vertical sub-pixels, but perhaps times have >changed) and the hinting to "Full". You can look at your screen with a magnifying glass, or drip of water and see the subpixels and their orientation and order. The settings can be changed per-user via config files, but I don't recall offhand where, as I don't have/use LCD displays, and never have to change such settings for any reason. A quick googling may yield the answer though. >There's one last problem remaining. The effect of this is only >temporary. If I log out and log back in, I have to re-run >gnome-font-properites again.
