Ubuntu 14.04 在我的 Dell Inspiron 14 3000 笔记本电脑上完全看不到触摸板及其按钮。重新安装 Ubuntu - 结果相同 - 没有触摸板。我运行了一些诊断程序,结果如下:

如需更多信息,请要求您对触摸板进行帮助,否则将恢复默认设置。
这个问题很容易解决,只要你知道答案!单击“添加”按钮以将某个飞行员的配置文件添加到“黑名单”,然后与触摸板侦测发生冲突。该过程很简单,只需打开终端(从 Unity 菜单开始,单击“终端”以返回应用程序和扫描器)并复印下一个命令(显示,在相应的入口处应用)
在终端中运行:
echo "blacklist i2c_hid" | sudo tee -a /etc/modprobe.d/blacklist.conf
然后重新启动,触摸板就应该正常工作了。
