如何修复Fontconfig错误

Question

每当Fontconfig由应用程序运行(在我的具体情况下，是蒸汽中的Civ )，它就会输出这个错误：

Fontconfig error: "/usr/local/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70: non-double matrix element
Fontconfig error: "/usr/local/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70: non-double matrix element
Fontconfig warning: "/usr/local/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 78: saw unknown, expected number

虽然应用程序并没有完全崩溃，但是当这个错误被打印并且音频继续运行时，视频就会冻结。

• Fontconfig错误是否导致了问题？
• 我该怎么解决呢？

编辑：

计算机为Ubuntu 14.04 32位。我怀疑这个问题与fontconfig有关，因为视频(Aspyr )在打印此错误时会结冰，就在shift选项卡蒸汽社区消息显示的时候。那篇文章格式错误、臃肿，而不是不显眼。下面是由steam 2> error.txt创建的文件，我在问题发生后将其杀死。

Answer 1

fc-cache -v | grep -i err

也会在第78行给你一个错误(对我来说)。结果是，<matrix>元素在/etc/fonts/conf.d/10-scale-bitmap-fonts.conf中只有两个<name>元素，而它应该只有一个。做：

sudo nano "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf"

并删除另一行内容如下：

<name>pixelsizefixupfactor</name>

使fc-缓存查询不再返回错误，并且当加载蒸汽(和随后的游戏)时，Fontconfig error:行不再存在。

根据http://linux.die.net/man/5/fonts-conf，我想我们需要<matrix>中的4个<double>元素，但似乎没有必要。

Answer 2

试着关掉蒸汽覆盖层。右击游戏库中的游戏，选择“属性”，并取消选中“启用蒸汽覆盖在游戏中”。这个帮我修好了。

Answer 3

有人提到了这里这个解决方案：

只需删除/usr/local/etc/fonts/fonts.conf文件中的fontconfig即可。

你能试试吗？

要找出导致视频冻结问题的真正原因，请执行以下操作：

• 在一个终端的命令行中启动steam .
• 在另一个终端的命令行中启动Civ。find蒸汽目录中的可执行文件(Ubuntu上的~/.local/share/Steam)，如下所示：find ~/.local/share/Steam/ -executable -type f | grep -i civ
• 好玩的时候！播放Civ V，直到您体验到错误。快杀了Civ。
• 查看steam和civ二进制文件的输出，并将其张贴在这里或Google以获得如下错误信息：" Error : Term"，使用双引号。
