我输入xinput list之后这是所有的显示：
alvin@alvin-Blade:~$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ COMPANY USB Device id=12 [slave pointer (2)]
⎜ ↳ COMPANY USB Device id=13 [slave pointer (2)]
⎜ ↳ Razer Razer Blade id=14 [slave pointer (2)]
⎜ ↳ Razer Razer Blade id=15 [slave pointer (2)]
⎜ ↳ Razer Razer Blade id=17 [slave pointer (2)]
⎜ ↳ ELAN Touchscreen id=18 [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=9 [slave keyboard (3)]
↳ USB Camera id=10 [slave keyboard (3)]

↳ Razer Razer Blade id=16 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=19 [slave keyboard (3)]
alvin@alvin-Blade:~$
并没有哪个显示是触摸板。。
然后我输入了下面3个sudo的命令，下面是电脑输出的：
alvin@alvin-Blade:~$ sudo trackpad show
[sudo] password for alvin:
sudo：trackpad: command not found
alvin@alvin-Blade:~$ sudo trackpad tap
sudo：trackpad: command not found
alvin@alvin-Blade:~$ sudo trackpad drag
sudo：trackpad: command not found
alvin@alvin-Blade:~$
所以我觉得电脑并没有识别出我的触摸板，或者是制造厂商改了触摸板的硬件名导致系统只能识别到改过的名字而不是触摸板原名，所以才不能使用正常驱动，有什么解决方法么？
