Just install Manjaro xfe with proprietary driver, my touchpad not working (SOLVED)

Hey guys, i am new with manjaro so i kindly need some help
so i just install it using open source driver, after installing the nvidia driver from hardware configuration i restart it and then it won’t start showing the screen just blank. So i re-install it but now i choose proprietary driver, everything seems okey the nvidia installed with the hybrid driver because my laptop have intel and nvidia mx150. but then the touchpad not working at all. i need help so i can use my touchpad. thanks guys. oh yeah i am still new so i am not familiar with manjaro commands

Problem solved, turn out i accidentally pressed F7 on my keyboard which is turn on/off my touchpad
