fanhe 写了：你改改次像素顺序看看，在我这里如果微调不为轻微的话都会偏色的
不关顺序的事，那样只是 横着偏色或竖着偏色而已。

我感觉还是 libcairo2的版本问题。。
我用libcairo2－1.2.4就不偏色 用1.4.2高版本就偏色，其他配置都不动。
但是用1.2.4 一些程序不能运行，如beryl。

我发现，如果关闭rgba，就不会产生偏色现象了。

代码： 全选

 <match target="font">
 <edit mode="assign" name="rgba">
 <const>none</const>
</edit>
</match>
我在fluxbox中关闭了rgba以后，字体正常，并使用最新的cairo，但是GNOME下，我不知道如何关闭次像素LCD的RGBA，请赐教！

rgba 用 none 就变成灰度平滑了，当然字体不会偏色。关键是关了次像素平滑字体会难看很多。

gnome 在字体渲染细节里面修改。

但是打开了 次像素，始终是偏色，不知道怎么搞的。
关闭了RGBA 字体边缘稍微有一点模糊，不太明显。

那怎么搞？ 开了 次像素，就偏色。。。我都找不到原因了。。。

看了下，的确模糊很多。开始不觉得。看着看着就觉得模糊很多了。。。。

大家都一样，我看到开次像素的都偏色，不过有的不是很明显而已。
我现在就不是很明显。
自我安慰，我看不见 :twisted: :twisted:

用caior2_1.2.4-2 freetype6_2.2.1-3 xft2_2.1.8.2-9
用这3个版本的包，就不会偏色。。。

但是这3个包版本太低了。用新版本的就偏色。

你Xorg 的 Module 加载了啥？？？我的如下。。。 不知道XFF会不会比freetype好。看的说freetype比xff高级。。。

和xorg无关吧
主要是看/etc/fonts/conf.d和/etc/fonts/conf.avail里有无支持LCD的
