ubuntu上多种软件都可能出现的,libgtk-x11-2.0.so.0库文件找不到

这个问题的产生,可能是因为在 64位系统上 ,缺少对32位的元兼容。 网络上的某些教程中,甚至建议了,在64位的系统刚装好的时候,就先把sudo apt-get install ia32-libs ia32-libs-gtk装上。 解决办法: sudo apt-get install ia32-libs ia32-libs-gtk

linux 屏幕录像软件 Kazam 1.4.2 发布

中文输入法消失 ubuntu

Ubuntu12.04下ibus輸入法的圖標經常消失,輸入中文時很不方便,從測試版開始就有這個問題。如果實在需要,可以手動重啓一下ibus進程。

按Ctrl+ALT+T 快捷鍵打開終端,

輸入: killall ibus-daemon (結束進程)

ibus-daemon -d (重啓ibus) 因爲fcitx目前無法在dash窗口裏輸入漢字,於是準備退回到ibus,那還用上面的手工辦法就太費事了。做個腳本吧。

1、建立一個名叫:reset-ibus的文件,輸入如下內容 點擊(此處)摺疊或打開 #! /bin/sh killall ibus-daemon && ibus-daemon -d 2、給他賦予執行權限後扔到/usr/bin/目錄 點擊(此處)摺疊或打開 chmod a+x reset-ibus sudo mv reset-ibus /usr/bin 3、現在你在終端裏就能夠輸入reset-ibus來重新啓動ibus進程了。 4、進入系統後自動執行reset-ibus 5、還可以做一個快捷鍵,以避免意外要用到 如果建立腳本繁瑣,也可以直接採用如下方法: ibus圖標通知欄不顯示了。解決方法:打開“啓動應用程序”,打開添加一個啓動項,名稱和註釋隨意寫,命令裏面輸入ibus-daemon -d -x -r,保存。重啓。
