如何禁止我的系统进入睡眠状态？

Question 1

在 Ubuntu 16.04 LTS 上，我成功使用以下命令禁用挂起：

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

重新启用它：

sudo systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target

从man systemctl：

mask NAME...  
           Mask one or more units, as specified on the command line. This
           will link these unit files to /dev/null, making it impossible to
           start them. This is a stronger version of disable, since it
           prohibits all kinds of activation of the unit, including
           enablement and manual activation. Use this option with care. This
           honors the --runtime option to only mask temporarily until the
           next reboot of the system. The --now option may be used to ensure
           that the units are also stopped. This command expects valid unit
           names only, it does not accept unit file paths.

 unmask NAME...
           Unmask one or more unit files, as specified on the command line.
           This will undo the effect of mask. This command expects valid
           unit names only, it does not accept unit file paths.

Question 2

图形用户界面

你看过吗：

系统 -> 偏好设置 -> 电源管理

在交流电源选项卡上，将计算机在不活动时置于睡眠状态：“从不”

终端

你能打开“gconf-editor”吗？

在看：/apps/gnome-power-manager/timeout

尝试设置sleep_computer_ac为0

我不确定是否还需要进行其他更改。
