PART 1解決failed to write cache的問題
最近發神經把linux給格了，重裝，裝完中文支持，問題就來了，系統干什麼都變得奇慢，並且在APT－GET的時候出現了如下的顯示
Updating fontconfig cache...
/usr/share/fonts/X11: failed to write cache
/usr/share/fonts/X11/100dpi: failed to write cache
/usr/share/fonts/X11/75dpi: failed to write cache
/usr/share/fonts/X11/Type1: failed to write cache
/usr/share/fonts/X11/encodings: failed to write cache
。。
如果你的系統在APT的過程中也出現了這種情況，請繼續往下看。
我在網上搜到了個腳本，用來解決這個問題，把下面的做成腳本運行或者直接復制到終端中運行，然後就搞定了。
#!/bin/bash

PART 2啟動系統後無法自動進行pppoe撥號 解決的問題
一般情況下，在使用sudo pppoeconf中選擇自動撥號就應該好用，但偶這回就不好用了。。。
解決方法如下
在終端執行
sudo gedit /etc/network/interfaces
對配置文件進行編輯
然後把下面的文字添加到這個配置文件的結尾。
# added by pppoeconf
auto eth0
iface eth0 inet manual
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
auto dsl-provider
iface dsl-provider inet ppp
provider dsl-provider
