升级到 20.04 后，Ubuntu 上的锁定屏幕不起作用。我已在调整中将其打开，但它不起作用。当我单击“锁定”时，屏幕只会重新加载并在此过程中禁用一些扩展。它根本不起作用。我该如何解决这个问题？

天哪！@#$% 蝙蝠侠！你的 GNOME Shell 扩展实在是太多了，而且很多扩展的功能都存在重叠。
第一步...
去https://extensions.gnome.org/local/并禁用全部扩展，然后使用ALT+ F2，然后r，然后重新启动 GNOME Shell ENTER。然后重新测试锁定屏幕，看看它是否正常工作。
第二步...
让我们先清理一下您的/usr/share/gnome-shell/extensions...
sudo rm -r /usr/share/gnome-shell/extensions/*gcampax.github.com
使用前面的说明重新启动 GNOME Shell。
这应该会让你在/usr/share/gnome-shell/extensions...中得到这些扩展。

使用我之前提供的相同网址，删除任何剩余的扩展，这些扩展要么 1) 不是真正需要的，要么 2) 功能重叠。然后逐个重新启用剩余的扩展，看看其中一个扩展是否会导致锁屏问题。每次禁用/启用/删除更改后，重新启动 GNOME Shell。
