昨晚断电了，我进入了登录循环，然后屏幕缩放就开始了。经过大量搜索和尝试，我发现这
并尝试使用创建一个新用户sudo adduser test，sudo systemctl reboot我能够登录，并且它也被放大了。我关闭了缩放功能，ctrl + windows/super + 8但没有用。我还检查了缩放功能是否被禁用，结果是禁用了。之后，我回到 tty 并从上面的链接尝试了这个，并且能够登录我的真实帐户，但找不到 ~/.nvidia-setting-rc 和 ~/.nv：
mv ~/.config ~/.config.old mv ~/.local ~/.local.old mv ~/.cache ~/.cache.old mv ~/.nvidia-settings-rc ~/.nvidia-settings-rc.old mv ~/.nv ~/.nv.old sudo systemctl reboot
和：
sudo apt install --reinstall gdm3 pop-desktop gnome-shell sudo systemctl reboot
当我重新登录时，我得到了一个来自 Ubuntu 的欢迎窗口，就像我刚刚安装它一样，我侧面的工具栏恢复为默认设置，屏幕仍然放大，但我仍然保留了之前的所有文件和软件。据我所知，这个缩放问题是我现在遇到的唯一问题。其他一切似乎都运行良好，我现在登录了。
任何帮助都将不胜感激。谢谢。
