Right click doesn't work on HP mini 210 touchpad

is that i'm going to input:

sudo su (Enter your password)

echo options psmouse proto=exps > /etc/modprobe.d/psmouse.modprobe
reboot

p/s: since i'm a newbie, i need to confirm the command to solve my problem at hp mini 210-1073TU.

You may also be interested in installing gpointing-device-settings package, which will provide more configuration options for your touchpad.

sudo apt-get install gpointing-device-settings

Once installed you find it under System -> Preferences -> Pointing Devices.

try TAPPING the lower right corner of the touchpad instead of clicking the button

I've found a workaround which worked with my Lenovo Edge E320 with a clickpad.

Just create /usr/share/X11/xorg.conf.d/51.clickpad.conf and paste the following content:

Section "InputClass" 

Identifier "Default clickpad buttons"
MatchDriver "synaptics" 
Option "SoftButtonAreas" "50% 0 82% 0 0 0 0 0"

EndSection

After a restart of the xserver the clickpad worked just fine and the mulitouch features are now operational.
