我在一台配备 AMD A6-7310 处理器的华硕设备上运行 xUbuntu 16.04。问题是我无法暂停计算机。当我将屏幕放在键盘上时，屏幕变黑，但风扇仍在运转，背光也是如此。当我打开屏幕时，屏幕仍然是黑色的，背光停止，风扇仍在运转。然后，我需要按下一个按钮才能返回到一秒钟后出现的登录屏幕。
你知道我该如何解决我的问题吗？我尝试在启动时设置选项“nomodeset”，但问题仍然相同。
谢谢你！
以下是一些有用的命令：

我尝试着/etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'"
然后我运行sudo update-grub并重新启动，但问题仍然存在......

嗯，我觉得自己太蠢了。我不知道为什么，但是 xubuntu 被设置为在我关闭灯时锁定屏幕，而不是暂停它。这就是为什么它sudo pm-suspend毫无问题地工作了...我只是在System Preference/中更改了它Energy saving，现在一切都正常了。
