Understand since I've never seen anything in this life I cannot state what I'm about to from personal experience. However while I worked for the Navy, one day the building in which I worked had a short meeting and it was recommended by management that everybody switch over to Lucida Bright font since it was the most readable font available within windows at that time. If anyone needs an alternative and this font is available it may be worth a try.

It looks like you're right--getting this changed sounds like paddling upstream against a fairly high current!

That means that when 50% intensity is wanted, it produces 22% intensity instead: black-on-white is too thick, white-on-black is too thin.Thank you for confirming something I suspected for a long time. Do you know what program(s) is responsibe for the anti-aliasing, against which a bug might be filed (or maybe a bug has already been filed)?It is hard to tell, there are several components working together, and they all will try to shift the blame to each other. I tried filling it years ago, and it gave me that: http://bugs.freedesktop.org/show_bug.cgi?id=13431 If somebody dares tell me that the way of reading text that I chose is "wrong", I think it is worthless to try to discuss. The components in play are: - fontconfig: at some point, the user needs to be able to tell that gamma correction must be taken into account and what the gamma value should be. Despite what kp wrote, it belongs in fontconfig, just as much as lcdfilter or rgba. - Freetype: it is the component that rasterizes the vector fonts, including anti-aliasing, so it would be an easy place to adjust for gamma. Unfortunately, Freetype does not know the color of the text and background, its output could be considered an alpha map. - The X11 RENDER extension: it is the component that performs the alpha blending. It would be the correct place to implement the gamma adjustment. Unfortunately, it has no provisions to do so. - Xft: it is the glue that holds everything together. I do not think it needs any work for this issue. Good luck if you want to get things moving. Regards,
