我的笔记本电脑 (HP Elitebook 8570w) 出现问题 - 每当我关闭屏幕时，它就会进入睡眠/挂起/休眠模式（您可以选择此功能的名称）。当我重新打开笔记本电脑盖并且会话恢复时，一切都很好除了xfce4-panel 无法正确绘制（它要么是全黑的，要么会出现之前在屏幕该区域绘制的任何内容的伪影）。
当您单击按钮时，面板仍然有效，但它们不再绘制/更新。任何其他图形元素都会“绘制”在它上面，并且面板变得非常难以使用。描述它的最好方式是“图形损坏”或者“伪影”——但到目前为止，我还没有成功地看到网上其他人描述了与我遇到的完全相同的问题。
我尝试重新启动 xfce4-panel 进程，但它再次导致同样的结果。我尝试过重新启动其他一些 xfce 进程，也尝试过xrefresh其他操作，但没有成功。我摆脱它的唯一方法是注销并重新登录，但我丢失了所有窗口和东西，这非常烦人。我运行一个 VMWare 虚拟机和一堆其他东西，我想将它们保留在内存状态中，以便在我从挂起/休眠状态回来时恢复。
是否有其他进程可以重新启动以恢复我的面板，而无需完全退出并丢失会话？
任何对此问题的见解都将非常感激，即使它是某种解决方法。谢谢！
附加信息 -
笔记：
- 发现当我使用 Printscreen 截取屏幕截图时，绘制调用会通过一次并刷新面板，并且现有的工件将被删除（因此我什至无法截取发生的工件的屏幕截图）但它仍然不会继续之后更新。只需将鼠标悬停在任何“窗口按钮”区域上，就会打开一个带有窗口全名的工具提示，该窗口将覆盖面板区域并卡在那里，直到其他图形元素覆盖它。

答案1
这是我见过的唯一一篇提到这个具体问题的帖子。我还遇到了 Xubuntu 14.04 中的 XFCE 面板损坏的问题，在关闭笔记本电脑盖子后暂停。一旦我打开盖子，面板总是被损坏 - 通常只是黑色。桌面看起来不错，但如果我打开文件，最大化等各种按钮也丢失了。
如果我通过“注销”菜单暂停笔记本电脑，则没有问题。一切都完美地回来了。
经过一番思考后，我想到了重新启用桌面的“合成”选项的想法，我已禁用该选项以节省内存。启用合成为我解决了腐败问题。简单的。
我的笔记本电脑也是惠普的（尽管型号不同），但我不确定问题是否是惠普特有的。
希望这可以帮助某人。
