我的 xset 设置不断被重置。这导致我的显示器永远不会休眠。即使当我尝试使用该命令强制显示器进入睡眠状态时，xset dpms force off显示器也几乎立即重新打开。
我尝试拔掉鼠标以确保它不会导致鼠标事件触发显示。我也没有无线卡，所以我知道这不可能是此线程中讨论的 wifi 事件：

我没有安装 gnome-screensaver（它在上面的线程中被讨论为可能的罪魁祸首）。
我的命令的输出xset -q如下。我使用的是 Ubuntu 18.04 LTS。

我知道这表明我的显示器永远不应进入待机、暂停或关闭状态。然而，这是因为这些值不断被设置回 0。
我想知道这是否与我的 nvidia 驱动程序有关？这是 nvidia-smi 的输出：
