久沒有更新Ubuntu裡的Beryl，今天想試一試svn最新的Beryl環形視窗切換器(Ring Window Switcher), 就出了事。整個Beryl都crash了，出了：

libberylsettings: Couldn't get vtable from '/usr/lib/beryl/libdbus.so' plugin
libberylsettings: Couldn't get vtable from '/usr/lib/beryl/libcrashhandler.so' plugin
libberylsettings: Couldn't get vtable from '/usr/lib/beryl/libdecoration.so' plugin
libberylsettings: Couldn't get vtable from '/usr/lib/beryl/libwobbly.so' plugin
libberylsettings: Couldn't get vtable from '/usr/lib/beryl/libanimation.so' plugin

用apt-get --purge remove ......拆除Beryl再重新安裝都沒有。結果在Beryl Forum找到gourdin提無的解決方法，就是除了 purge 外，還要來個徹底大清洗。方法如下：

先拆除所舊版本Beryl的套件及其有關檔案：

apt-get remove --purge beryl beryl-core beryl-dev beryl-manager beryl-plugins beryl-plugins-data beryl-settings beryl-settings-bindings emerald libberyldecoration0 libberylsettings0 libemeraldengine0

找出所有殘餘的檔案 (除了在用戶home directory中個別用戶的設定檔外) 並放入檔案 /tmp/beryl.list

find / -iname '*bery*' | grep -v "^/home" > /tmp/beryl.list

你最好人手檢查一下 /tmp/beryl.list 有沒有你不想刪除的檔案，然後把裡面提給的檔案全部刪除：

xargs sudo rm -rf </tmp/beryl.list
sync

重新安裝beryl：

apt-get install beryl beryl-core beryl-manager beryl-plugins beryl-plugins-data beryl-settings beryl-settings-bindings emerald libberyldecoration0 libberylsettings0 libemeraldengine0

搞定後，你可以享受最新最酷的Beryl了!!! \(^O^)/
