KeePassX Global Autotype 与 VMware 一起使用时会损坏密钥

Question

我在 Arch Linux 上运行 VMWare Workstation，并将 KeePassX 设置为使用 ALT +“A”作为全局自动类型键绑定。

在运行 VMware 之前，KeePassX 运行良好。当 VMware 将键盘从来宾操作系统释放到主机时，“a”键完全停止工作（KeePassX gui 中和 VMware 中的来宾操作系统内部除外）。我向 xev 确认“a”键没有按应有的方式传递给 X，但似乎被另一个程序拦截（我猜测是 keepassx，因为它是“A”键工作的唯一应用程序）。

在主机上运行 $ showkey --keycodes 表明扫描码（0x1e 向下，0x9e 向上）仍在按预期生成。在第一次 VMware 键盘捕获之前，在主机上运行 xev 表明按键检测和映射正确（按“a”，然后按“shift + a”）：

$ xev

第一次 VMware 键盘捕获后，xev 不再检测到“A”按键，而是生成以下输出（按“a”，然后按“shift + a”）：

即使终止 VMware 服务后，问题仍然存在。通过注销/登录重新启动 X 会话可以纠正该问题。

我不确定是否要研究 VMware、KeePassX 还是我的桌面环境。
