gnome-panel 一直死机

我在 Ubuntu 21.10 上。我将 gnome-flashback 与 Compiz 结合使用。gnome-panel（版本：3.41.2）不知为何一直崩溃。这是日志文件，但我似乎找不到问题所在。

答案1

让我们尝试逐步修复每个警告或错误。

  1. 以下消息

    Gtk-Message: 14:07:17.772: Failed to load module "xapp-gtk3-module"

    可以通过安装对应包经过：

    sudo apt-get update
sudo apt-get install --reinstall xapps-common libxapp1

  2. 然后留言

    (gnome-panel:202571): Indicator-Appmenu-CRITICAL **: 14:07:18.369: Unable to register the object to DBus: An object is already exported for the interface com.canonical.AppMenu.Registrar at /com/canonical/AppMenu/Registrar

    应该通过安装来修复对应包经过

    sudo apt-get install --reinstall plasma-workspace-dev appmenu-registrar

然后重新启动并再次登录 GNOME FlashBack（Compiz）会话。

以下是一些个人看法。GNOME
FlashBack（无论是 Metacity 还是 Compiz）从长远来看都无法解决 GNOME Shell 可用性的下降。所以欢迎你去掉它并正常安装完全传统的稳定桌面名为伴侣这是 GNOME 2 的一个分支。请参阅这个答案.
MATE 的安装非常简单sudo apt-get install ubuntu-mate-desktop^。

答案2

答案似乎是从旧的 gnome-panel（Gnome2）转移到更受支持的东西，如 Mate 和 mate-panel。
