三,没有休眠(hibernate)选项
ubuntu 12.04 因为某些程序的bug,所以禁用的hibernate选项。
First, test hibernation works on yoursystem by running command:
sudo pm-hibernate
If everything is fine,you can continue to use this command to hibernate your system.
To get started, press Ctrl – Alt – Ton your keyboard to open Terminal. When it opens, run the commandsbelow to create a hibernate policy file.sudo gedit /var/lib/polkit-1/localauthority/50-local.d/hibernate.pkla
Then copy and paste the lines below into the file and save it.
[Re-enable Hibernate] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yesRestart your computer and you should see it.
