RT，我的电脑是synaptics的触摸板，支持多点触控，在win 8.1下支持各种多指手势。
现在转到ubuntu之后，没有了多指手势，只能点住窗口右边来滑动，非常不方便。
看了一下在系统设置-鼠标和触摸板里面也没有显示触摸板，求解怎么开启synaptics触摸板的多指触控功能？
多谢了！

man synaptics
都在这了

我输入了
cat /proc/bus/input/devices > ~/devices
xinput --list > ~/xinput
cat /var/log/Xorg.0.log > Xorg.0.log
之后一点反应也没有。。完全没有输出任何东西。。

输入xinput list之后：
alvin@alvin-Blade:~$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Razer Razer Blade id=11 [slave pointer (2)]
⎜ ↳ Razer Razer Blade id=12 [slave pointer (2)]
⎜ ↳ Razer Razer Blade id=14 [slave pointer (2)]
⎜ ↳ ELAN Touchscreen id=15 [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)]
↳ Video Bus id=8 [slave keyboard (3)]
↳ Power Button id=9 [slave keyboard (3)]
↳ USB Camera id=10 [slave keyboard (3)]
↳ Razer Razer Blade id=13 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=16 [slave keyboard (3)]
没找到我的触摸板啊，感觉像是没找到这个触摸板

看起来现在的问题是电脑没把触摸板识别出来，可能是电脑厂商给触摸板定的名字不是默认的synaptics触摸板，所以没法识别，有什么办法改一下么？看了这俩网址都是能识别到触摸板的。。现在我的是识别不出来但能使用，好不方便。。。打字的时候都影响

求解这是咩 0.0

查看 Synaptics 设置的命令啊
看看我的
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech USB Receiver id=10 [slave pointer (2)]
⎜ ↳ Logitech USB Receiver id=11 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=13 [slave pointer (2)]
⎜ ↳ TPPS/2 IBM TrackPoint id=14 [slave pointer (2)]

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)]

⎜ ↳ 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)]

↳ 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？

这是我输入xinput list之后的输出，并木有touchpad之类的。。。。求破 0.0

alvin@alvin-Blade:~$ xinput list
