Xubuntu - Disable Mouse's Right Click

To disable right click for just desktop :

xmodmap -e "pointer = 1 2 99"

To apply for system wide:

xmodmap -e 'pointer = 1 2 0 4 5 6 7 8 9'

If you want to reverse it:

xmodmap -e 'pointer = default'

But, notice that it will restore to defaults upon rebooting.So, create an autostart script as following in ~/.config/autostart/disablerightclick.desktop:

[Desktop Entry]
Encoding=UTF-8
Version=0.9.4
Type=Application
Name=Disable Right Click
Comment=Disable Right Click
Exec=xmodmap -e "pointer = 1 2 99"
StartupNotify=false
Terminal=false
Hidden=false


Restart and log-in again to see it work.
