那些遇到过的问题

Ubuntu 18.04 不会停止黑屏

Rou*_*tor 7 lock-screen

这是 17.10 中的一个问题，它一直延续到 18.04，此时它让我发疯。

闲置一分钟后，我的屏幕一直黑屏。我什至无法阅读文章。

在 Gnome 设置中，Privacy > Lock screen关闭，我已经设置Power > Blank Screen为Never并且Automatic Suspend设置为Off

我还需要禁用什么？我会决定何时锁定屏幕。我只想把这一切都关掉。

更新

我检查并排除的其他事项：

我已经安装了 Dconf Editor 并检查了那里的设置，但我找不到任何改变行为的东西。我尝试禁用下的idle-dim设置/org/gnome/settings-daemon/plugins/power并尝试禁用整个电源插件，这两种更改都没有对行为产生影响。

我还梳理了该nvidia-settings应用程序，在那里找不到与电源或屏幕消隐相关的任何内容。我的 xorg 服务器正在使用开箱即用的自动检测进行启动，并且我的系统上没有 xorg.conf 设置任何内容。这对我来说只是默认的 18.04 行为。

发现这个问题并检查xset q输出，添加它。你会注意到我的timeout和cycle设置是0那里的解决方案，但是我的已经设置为 0 并且我的屏幕仍然是空白的。无论如何，这个问题是针对 Unity 的，而我的是针对 Gnome3

根据@WinEunuuchs2Unix，我已经检查、更改并重新检查了此问题中的设置，但问题仍然存在。

另一方面，这些需要像这样手动更改的设置似乎是 Ubuntu 早就应该修复的一个长期存在的错误，因为这些是我认为我在上面的电源设置中关闭的确切设置。

我遇到了类似的问题，直到我通过软件应用程序安装了一个名为“caffeine”的 gnome 扩展。

此问答似乎描述了您的情况：即使禁用电源设置，屏幕也会在空闲时关闭

总结一下答案，首先发现您的选择：

gsettings get org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout
gsettings get org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout
gsettings get org.gnome.desktop.screensaver idle-activation-enabled
gsettings get org.gnome.settings-daemon.plugins.power idle-dim

然后设置它们：

gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout 0
gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 0
gsettings set org.gnome.desktop.screensaver idle-activation-enabled false
gsettings set org.gnome.settings-daemon.plugins.power idle-dim false
