我在我的新 Latitude E5570 上全新安装了 ubuntu 16.04。鼠标/触摸板设置只有“常规”和“鼠标”部分,无法更改触摸板选项(如反向滚动)。xinput 命令返回:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ImPS/2 Generic Wheel Mouse id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ Integrated_Webcam_HD id=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
↳ Dell WMI hotkeys id=13 [slave keyboard (3)]
↳ DELL Wireless hotkeys id=14 [slave keyboard (3)]
看来它无法识别触摸板。如何让 ubuntu 加载正确的驱动程序?
