这是我的系统规格，我感觉这是 System76 或 Nvidia GTX 970M 特有的：
- System76-Serval WS（serw8）
- Ubuntu 16.04.1 LTS（64 位）
- 6 GB GeForce GTX 970M – 1280 CUDA 核心
- 3.6 GHz i7-4790（8MB 缓存 – 4 核 – 8 线程）
- 16 GB HyperX 双通道 DDR3，1866MHz（2× 8GB）
- PCIe (M.2)、SSD、HDD
我遇到了不一致的暂停问题，当从暂停状态唤醒时，它有时但频繁地醒来后发现屏幕变黑。
在 systemd suspend 和 suspend 中都发生过这种情况pm-suspend。
当屏幕变黑时，按下电源按钮、按下睡眠按钮、尝试任何组合键以及关闭并重新打开盖子都不起作用。我唯一能做的就是硬关机或Alt+ SysRq+ ( RIESUB) 进行硬重置。
我尝试了一些不同的 Nvidia 驱动程序，但都无济于事。我尝试使用开源 nouveau 驱动程序，但它们的分辨率不佳，而且非常坏的。
这是我当前的驱动程序版本（通过system76-driver-nvidia包提供）：367.27 from nvidia-367 (open source)
我曾就此问题咨询过 System76，但很遗憾，他们也束手无策。他们认为这与 systemd 有关，但我不确定，他们也不确定。
/var/log/pm-suspend我在崩溃后检查过，它是空的。这是它正常工作时显示的内容：

所以这是一个非常棘手的问题，我愿意尝试任何方法（在合理范围内），所以如果你有任何想法，请告诉我。我真的很想解决这个问题，因为我在大学使用我的笔记本电脑，当从挂起状态唤醒时，必须随机进行硬重置，就像掷骰子一样，这非常令人失望和危险。
