I have installed Ubuntu 12.04.1 on my new Lenovo IdeaPad Y580 M772DGE. Unfortunately the right mouse button of the touchpad is not working correctly. Every mouse button click is interpreted as a left mouse button click. I tried to uninstall and reinstall the synaptics (xserver-xorg-input-synaptics) drivers, but the problem is still present.

What else can I do? Any other suggestions? Is it possible to emulate a right mouse click event with a keyboard key?

I think I can give you the answer

Open a terminal, then type:

echo "options psmouse proto=exps" | sudo tee /etc/modprobe.d/psmouse.conf

Enter your password when prompted and then press Enter.

Now, while your right mouse click should be working after a reboot, you can try doing it without a reboot, but it might crash your desktop. It didn't for me, so here it is, type in the same terminal as root:

sudo modprobe -r psmouse; sudo modprobe psmouse

hope that helps!

edit: ok, so now that the right button works, the touchpad section of the mouse settings disappeared, and so did my custom settings and the multitouch capability, which resulted in a slow mouse pointer and no ability to scroll. I think I'll write a bug report on this one.

edit2: I searched through the web, and apparently, there is some obscure way to fix this problem, but it relies on ressources and patches that aren't available so easily anymore. I fixed this problem for me by upgrading to quantal quetzal, which includes adequate (albeit not great) support for multitouch clickpads by default

The top answer by @elpollodiablo did not work for me on Ubuntu 18.1 on a Dell Inspiron 15 5000 series. As for the second answer, I do not have a file /usr/share/X11/xorg.conf.d/50-synaptics.conf to edit.

Instead I found this link instructing me to install Gnome Tweaks -> Keyboard -> Touchpad -> Mouse Click Emulation. http://ubuntuhandbook.org/index.php/2018/07/touchpad-right-click-not-working-in-ubuntu-18-04/

That worked.

Find and open the file: /usr/share/X11/xorg.conf.d/50-synaptics.conf

Find the paragraph : 

# This option enables the bottom right corner to be a right button on clickpads
# and the right and middle top areas to be right / middle buttons on clickpads
# with a top button area.
# This option is only interpreted by clickpads.
Section "InputClass"
        Identifier "Default clickpad buttons"
        MatchDriver "synaptics"
        Option "SoftButtonAreas" "50% 0 82% 0 0 0 0 0"
        Option "SecondarySoftButtonAreas" "58% 0 0 15% 42% 58% 0 15%"

Add 2 line before Option "SoftButtonAreas" "50% 0 82% 0 0 0 0 0"

Option "ClickPad"         "true"
Option "EmulateMidButtonTime" "0"
