为什么我的鼠标指针老是跳到屏幕右侧？

我的鼠标指针大约每分钟一次跳到显示器的右侧。我禁用了psmouse，并且usbhid发生了同样的事情，所以这可能不是鼠标/触摸板硬件/驱动程序问题。两者都没有Xorg.0.log。

我在运行 Debian Jessie 和 XFCE 的 Lenovo W541 上设置了两台显示器，如下所示：

知道什么会导致这种情况以及如何解决它吗？

答案1

我意识到只有当我进行 Webex 会话时才会发生这种情况。我使用 IceWeasel 和 OpenJDK 7（NPJP2 插件是/usr/lib/jvm/java-1.7.0-openjdk-i386/jre/lib/i386/IcedTeaPlugin.so）。我只是为了 Webex 安装了 Firefox 41 和 Oracle Java 7，光标不再跳跃。
