在 gnome classic 上显示日期

打开 terminal, 运行以下指令 

# 0：00 AM/PM
gsettings set com.canonical.indicator.datetime show-clock true
# Mon - Sun
gsettings set com.canonical.indicator.datetime show-day true
# 1 Jan - 31 Dec 
gsettings set com.canonical.indicator.datetime show-date true

也可以安装 dconf-editor 工具来设置

sudo apt-get install dconf-tools
