锁定屏幕在 Ubuntu 20.04 上不起作用

Question

升级到 20.04 后，锁定屏幕在 Ubuntu 上不起作用。我在调整中打开了它，但它不起作用。当我单击“锁定”时，屏幕会重新加载并在此过程中禁用一些扩展。它根本不起作用。我怎样才能解决这个问题？

Answer 1

天啊！@#$% 蝙蝠侠！您已经拥有太多的 GNOME Shell 扩展，而且其中许多扩展在功能上是重叠的。

第一步...

转至https://extensions.gnome.org/local/并禁用所有ALT扩展，然后使用+ F2、然后r、然后重新启动 GNOME Shell ENTER。然后重新测试锁屏，看看是否正常。

第二步...

让我们从清理你的/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。

/usr/share/gnome-shell/extensions这应该会让你在...中留下这些扩展。

drwxr-xr-x  3 root root 4096 May  9 18:04 ubuntu-dock@ubuntu.com

使用我之前提供的相同 Web 位置，删除您 1) 并不真正需要或 2) 功能重叠的任何剩余扩展。然后一次重新启用其余的扩展程序，看看其中一个扩展程序是否会导致您的锁定屏幕问题。每次禁用/启用/删除更改后重新启动 GNOME Shell。
