近日Debian更新贴士(fontconfig, fc-cache, 程序启动变慢)

现在程序是快了。
但是为什么屏幕上的很多字都需要用鼠标滑过或者移动窗口才能看到呢？
字体缓存有问题么？

如果用 root 权限执行 fc-cache 出现 failed to write cache 提示，原理是这样的：
新版本的 fontconfig 和 fontconfig-config 在 /etc/fonts/fonts.conf 里面
新增加了两行
<cachedir>/var/cache/fontconfig</cachedir>
<cachedir>~/.fontconfig</cachedir>
如果 upgrade 的时候没有用 apt 带的 fonts.conf ，可以手动加入这两行

来源：Debian bug report logs - #387928


另外，一个小提示：/etc/fonts/conf.d/70-no-bitmaps.conf 的存在会让文泉驿点阵
字体无法被 fc-cache 出来

补充：

<cachedir>/var/cache/fontconfig</cachedir>
<cachedir>~/.fontconfig</cachedir>

放在fonts.conf

<dir>/usr/share/fonts</dir>

上面，提供我的fonts.conf

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<!-- /etc/fonts/fonts.conf file to configure system font access -->
<fontconfig>
<!--
DO NOT EDIT THIS FILE.
IT WILL BE REPLACED WHEN FONTCONFIG IS UPDATED.
LOCAL CHANGES BELONG IN 'local.conf'.
The intent of this standard configuration file is to be adequate for
most environments. If you have a reasonably normal environment and
have found problems with this configuration, they are probably
things that others will also want fixed. Please submit any
problems to the fontconfig bugzilla system located at fontconfig.org
Note that the normal 'make install' procedure for fontconfig is to
replace any existing fonts.conf file with the new version. Place
any local customizations in local.conf which this file references.

by disabling hinting manually at smaller sizes (< 8ppem)

我试了1,19,22楼的方法，fc-cache -f -v 还是无法写入cache，系统是今天刚装的etch，也升级过了。还有什么解决的办法吗

我试了1,19,22楼的方法，fc-cache -f -v 还是无法写入cache，系统是今天刚装的etch，也升级过了。还有什么解决的办法吗

我也是刚装的etch，加了两个字体tahoma 和simsun,出现错误，用以下方法处理：
1、在fonts.conf的..................<dir>~/.fonts</dir>后加入：
        <cachedir>/var/cache/fontconfig</cachedir>
        <cachedir>~/.fontconfig</cachedir>
2、apt-get install fontconfig fontconfig-config --reinstall
3、ok!

冰封尘

只要sudo touch上边所有“failed to write cache”的路径就可以了。
sudo touch /usr/share/fonts
sudo touch /usr/share/X11
…
…
sudo touch /var/lib/defoma/fontconfig.d/u

烟雨平生

小弟用Etch，将windows下的truetype字体直接复制到/usr/share/fonts/X11/myfonts/下（myfonts是自己建立的目录），然后fc-cache -f -v 很快就搞定了，可以在“字体”中直接选windows下的字体了。

把这个帖子移出置顶吧，已经过去这么久了，现在应该很少人遇到这个问题了。
