正如标题所述，我的 Kubuntu 12.04 遇到了这个问题。
起初我以为是整个系统死机了，但 5 分钟前又发生了这种情况，虽然键盘和触摸板停止工作，但音乐仍在播放，所以我猜这只是一个“输入”问题，因为系统仍在运行！
有什么解决办法吗？
您需要了解有关我的设置的一些数据吗？

答案1
创建一个文件 psmouse.conf，使用以下文本选项psmouse proto=imps
保存为 root 权限，/etc/modprobe.d/
这样鼠标问题就解决了
答案2
我的 ASUS EEEPC 1015B（12.04x64）上遇到了这个问题，这纯粹是内核问题，因为新的 12.10 Quantal 在同一台机器上运行良好。
