我遇到了一个奇怪的问题。我意外升级到了 nvidia-driver-550，出现了严重的延迟问题。
使用键盘或计时的时候，这一点非常明显。
我怎么知道滞后与 GPU 有关？
- 我恢复了 nouveau 驱动程序，一切都运行良好，但是由于屏幕数量太多，CPU 变得疯狂，所以我想使用 GPU。
我尝试过什么？
- 我曾尝试使用 ubuntu-drivers 安装版本 525。但它认为它已经安装好了。
- 我已经使用以下方法清除了所有 nvidia
sudo apt-get --purge remove *nvidia* - 我尝试按如下方式安装 525
sudo apt install nvidia-driver-525- 然而，如果你研究软件包，只需在重新启动后重新安装 550，你就会发现它是 550 而不是 525。

nvidia-dkms-525以尝试解决最后一个问题，但没有成功。
我没主意了，唯一的解决办法是重新安装和设置我的开发机器，这很麻烦，但说实话

检查问题是否与Ubuntu 22.04.4 终端上的输入延迟
mutter如果是这样，您应该使用此 ppa 提供的方法修复滞后问题：
sudo add-apt-repository ppa:vanvugt/mutter
sudo apt update
sudo apt upgrade
