Flo's questions

我想将辅助显示器的刷新率降低到非常小的水平，这样我的 GPU 就不必做太多的工作了。但是在默认的“显示”设置中，没有选项可以更改我的第二台显示器的刷新率。它似乎固定在 60 Hz。

如何将第二台显示器的刷新率限制为仅，例如每秒 10 帧？...释放我的 GPU 上的一些资源。

这是我的显示设置：

我在 NVIDIA X 服务器设置中也找不到选项：

的输出xrandr是

因为 emojis 没有在 Chromium 中显示，所以我必须fonts-noto-color-emoji通过以下方式安装：

sudo apt reinstall fonts-noto-color-emoji

然后表情符号工作得很好。

但是重新启动我的机器后，表情符号再次停止工作。

有什么东西，我必须配置在启动时引导包吗？或者出了什么问题？

我在 Linux 安装程序的帮助下安装了 Davinci Resolve 16。当我启动程序时，什么也没有发生。所以我决定检查日志输出。因此，当我跑步时

/opt/resolve/bin/resolve

开始解决，我得到这个输出：

可能出现问题是因为我没有 NVIDIA GPU（我有 Intel Iris Plus Graphics）。在我的另一台配备 NVIDIA GPU 的机器上，它工作正常。

也许我需要为英特尔显卡安装驱动程序？

我的系统：

我在一个文件夹中有很多视频，我想用一个命令将它们全部压缩。

要压缩我使用的一个视频：

sudo apt-get install ffmpeg
ffmpeg -i input.mp4 output.mp4

但是，如果我有很多要压缩的视频怎么办？我尝试了以下方法：

ffmpeg -i ./videos ./compressed-videos

但后来我得到这个错误：

./videos: Is a directory

我已经nvidia-driver-415为我的 Dual GTX 970s 安装了通过软件和更新。重新启动后，我的屏幕分辨率现在停留在 1024x 768 像素。我有两台显示器，现在只有一台在工作。

我还注意到我的电脑现在发出更多的噪音。重叠窗口也有一些奇怪的故障。

这是我的系统规格：

我将衷心感谢您的帮助！我厌倦了重新安装 Ubuntu 只是为了解决这个愚蠢的问题。

顺便说一句：即使将驱动程序设置回 X.org S 服务器，问题仍然存在 - 来自 xserver-xorg-vidoe-nouveau（开源）的 Nouveau 显示驱动程序。
