自从更新到 Ubuntu 21.10 后，我的锁屏就不再起作用了。我正在使用 budgie 桌面，按Super+L锁定屏幕，系统日志中发生了这种情况：

在这里找到了解决方案：
https://discourse.ubuntubudgie.org/t/lockscreen-not-working-after-update-to-21-10/5394/20
正确 - 所以 gnome-shell 在这里搞砸了 budgie。
这有用吗？
pkill -9 -f /usr/bin/gjs /usr/share/gnome-shell/org.gnome.ScreenSaver 等待几秒钟，然后尝试运行
gnome 屏幕保护程序

谢谢你的想法！我从 Ubuntu Budgie 20.04 升级到 22.04 时也遇到了同样的问题，“锁定”按钮停止工作。删除 gnome-shell 后它又开始工作了：sudo apt-get remove gnome-shell。
但是 (!) 不幸的是，结果是我桌面上的所有图标都停止了工作，并且即使重新安装了 gnome-shell 后单击任何图标也没有任何反应。
