我最近在我的笔记本电脑 Dell Inspiron 1520 上安装了 Ubuntu 14.04。安装后，可以检测到触摸板，但垂直和水平滚动以及左键和右键单击不起作用。因此，我使用以下命令调整了 synclient 配置
synclient -l
发现滚动功能被禁用了，所以启用了它。我尝试了很多次，但还是找不到启用右键和左键的方法。我的笔记本电脑的触摸板与 url 中的图像相同。

请帮我解决这个问题。

没有保证，但通过网络搜索，你的问题看起来与 xorg.conf 有关。
我将尝试：
sudo apt-get install xserver-xorg-input-synaptics
sudo gedit /etc/X11/xorg.conf
然后加：
# **********************************************************************
# Modules section. This allows modules to be specified
# **********************************************************************
Section "Module"
Load "synaptics"
EndSection
# ******************************
# Files section
# ******************************

# ******************************
# Core Pointer's InputDevice section

然后重新启动 X（最后一个命令将带您进入登录 gdm，因此保存您之前所做的事情！）：
sudo restart lightdm
