ubuntu systray(系统托盘)图标问题--systray上应用程序的图标无法显示:1, install dconf-tools, and run "dconf editor".2, add your application(want to show in systray) to Desktop -> Unity -> Panel.e.g.-systray-whitelist ['JavaEmbeddedFrame', 'Wine', 'Update-notifier']+systray-whitelist ['JavaEmbeddedFrame', 'Wine', 'Update-notifier', 'skype']3, then logout and try again.--安装早期ubuntu版本里,系统负载小控件:1, sudo apt-get install indicator-multiload2, run "system load indicator"
