升级到 14.04 后，向下箭头不起作用/操作似乎在 Xserver 上分配错误

升级到 14.04（从 12.04）后，图形系统上的向下箭头不再正常工作。在控制台上，该键可以正常工作，但在终端上（在 X 内）则不行。不幸的是，我在互联网上搜索时没有找到答案，也许我找错了标签/关键词。不过，我找到了一些提示来检查按钮行为xev。左、上、右和下的键序列结果显示如下：

如您所见，向下箭头的行为不同，但有人知道如何修复它吗？

答案1

不知何故，向下的箭头键被设置为“显示桌面”。

弄清楚了这一点后，我就可以取消它了。

对于那些遇到类似问题的人来说，你可能会发现这个页面很有帮助：https://wiki.ubuntu.com/Keybindings。至少它解决了我的问题。
