我从联想带来了Thinkpad T440，并在上面安装了Ubuntu 13.10。它运作良好，但存在一个大问题：单击几秒钟后鼠标通常会冻结，有时鼠标会永久冻结，直到我删除psmouse模块并重新添加它：
sudo modprobe -r psmouse
sudo modprobe psmouse
之后，触摸板将再次正常工作，如果仍然冻结，则必须重新启动笔记本电脑。我不确定，但是驾驶员可能会遇到问题吗？这是dmesg输出的有趣部分：

有人可以帮我吗？
这是硬件问题，应该可以在其他操作系统（例如Windows 7）中重现。Windows 8驱动程序显然具有某种解决方法（也许可以更快地重新连接或忽略这些错误情况）。该问题（至少就我而言）很容易解决-触摸板电缆会四处移动并在我按触摸板按钮时断开连接-您应该能够通过确定是否仅在按下按钮时看到上面显示的错误来确认这一点。触摸板向下。
解决方案是让联想更换触摸板，或者自己修复触摸板。就我而言，我将触摸板电缆重新布线到电池下方，这样当我推动触摸板时电缆不会松动。这仅花费了几分钟，因此，如果您已经打开笔记本电脑的底部，则可能不会有任何损失。
