刚开始到网上下载了一个font.ini文件覆盖到/usr/share/opera/defaults/目录中，却发现并不那么完美。于是自己改动了下那个文件

也就是把所有字体去掉，只留下WenQuanYi Micro Hei，这下痛快了……

接着在“工具”→“首选项”→“高级”→“字体”中的“浏览器菜单”和“网页字体”都用上“文泉驿微米黑”，“网页<pre>”上选择“文泉驿等宽微米黑”。“国际字体”中选择“简体中文”。

效果如下：

最大的问题是我的blog正文怎么像是楷书而不是黑体字，那这是什么字体呢？

输入法嘛，还算简单，先安装scim-qtimm

sudo apt-get install scim-qtimm

接着

sudo gedit /usr/bin/opera

在

OPERA_BINARYDIR=/usr/lib/opera

之后加入

export export QT_IM_MODULE=SCIM

最后把Ctrl+Space打开主页的快捷键删除即可。

这里说一下，字体的更换。

为了照顾所有登录用户，把字体文件复制到/usr/share/fonts/目录下，如果是自己使用只要~/.fonts就可以了。

1、使用文泉驿微米黑作为演示，发行版为ubuntu9.04（因为该版本软件仓库中没有微米黑的软件包，只能自己复制）。复制字体到/usr/share/fonts/下的一个新目录里（为了方便管理），例如我的字体位置是：/usr/share/fonts/wenquanyi/wqy-microhei.ttc。

2、给予字体权限：sudo chmod 755 /usr/share/fonts/wenquanyi/wqy-microhei.ttc

3、进入字体目录，并刷新字体缓存

cd /usr/share/fonts/wenquanyi/

sudo mkfontscale

sudo mkfontdir

sudo fc-cache -fv

4、接着编辑配置文件：sudo gedit /etc/fonts/conf.d/69-language-selector-zh-cn.conf

我的配置文件如下：

<fontconfig>

<match target=”pattern”>

<test qual=”any” name=”family”>

<string>serif</string>

</test>

<edit name=”family” mode=”prepend” binding=”strong”>

<string>WenQuanYi Micro Hei</string>

<string>AR PL UMing CN</string>

<string>AR PL ShanHeiSun Uni</string>

<string>WenQuanYi Bitmap Song</string>

<string>Bitstream Vera Serif</string>

<string>DejaVu Serif</string>

<string>AR PL UKai CN</string>

<string>AR PL ZenKai Uni</string>

</edit>

</match>

<match target=”pattern”>

<test qual=”any” name=”family”>

<string>sans-serif</string>

</test>

<edit name=”family” mode=”prepend” binding=”strong”>

<string>WenQuanYi Micro Hei</string>

<string>Bitstream Vera Sans</string>

<string>DejaVu Sans</string>

<string>WenQuanYi Zen Hei</string>

<string>AR PL UMing CN</string>

<string>AR PL ShanHeiSun Uni</string>

<string>WenQuanYi Bitmap Song</string>

<string>AR PL UKai CN</string>

<string>AR PL ZenKai Uni</string>

</edit>

</match>

<match target=”pattern”>

<test qual=”any” name=”family”>

<string>monospace</string>

</test>

<edit name=”family” mode=”prepend” binding=”strong”>

<string>WenQuanYi Micro Hei Mono</string>

<string>Bitstream Vera Sans Mono</string>

<string>DejaVu Sans Mono</string>

<string>WenQuanYi Zen Hei</string>

<string>AR PL UMing CN</string>

<string>AR PL ShanHeiSun Uni</string>

<string>WenQuanYi Bitmap Song</string>

<string>AR PL UKai CN</string>

<string>AR PL ZenKai Uni</string>

</edit>

</match>

</fontconfig>

就是在serif、sans-serif、monospace 的字体的最前方分别加上：<string>WenQuanYi Micro Hei</string>、<string>WenQuanYi Micro Hei</string>、<string>WenQuanYi Micro Hei Mono</string>

其中最后一项是等宽字体，应该填入文泉驿等宽微米黑。修改配置文件的好处是不要再去修改应用软件的字体，达到系统的字体统一（Flash和JAVA除外）。

其中JAVA字体的更改：

在ubuntu下安装sun Java 6后发现中文字体有“口口”出现，解决办法如下：
sudo /usr/lib/jvm/java-6-sun/jre/lib/fontconfig.properties
在文件中加入：
filename.-misc-文泉驿微米黑-medium-r-normal–0-0-0-0-p-0-iso10646-1=字体文件的完整目录
allfonts.chinese-arphic1=-misc-文泉驿微米黑-medium-r-normal–0-0-0-0-p-0-iso10646-1
把文件中其余的allfonts.chinese-arphic……注释掉，保存即可。

Flash字体更改：

sudo gedit /etc/fonts/conf.d/49-sansserif.conf

我的文件如下

<?xml version=”1.0″?>

<!DOCTYPE fontconfig SYSTEM “fonts.dtd”>

<fontconfig>

<!–

If the font still has no generic name, add sans-serif

–>

<match target=”pattern”>

<test qual=”all” name=”family” compare=”not_eq”>

<string>文泉驿微米黑</string>

</test>

<test qual=”all” name=”family” compare=”not_eq”>

<string>文泉驿微米黑</string>

</test>

<test qual=”all” name=”family” compare=”not_eq”>

<string>monospace</string>

</test>

<edit name=”family” mode=”append_last”>

<string>文泉驿微米黑</string>

</edit>

</match>

</fontconfig>

其中的文泉驿微米黑可以改为你喜欢的字体。

如果不更改配置文件，那只有手动更改每个应用程序的字体了

1、系统字体（以Gnome为例）：系统→首选项→外观→字体。选择文泉驿微米黑。有些可以自定义字体的应用程序还需要另外调整，例如Firefox。
