    Ubuntu touchpad only works when pressing down

    HP Envy laptop with Ubuntu 18 BUT the touchpad has stopped working... not sure, probably something I did somewhere.

    The pointer doesn't move at all unless you press down on the pad then drag the pointer - no pressing on the touchpad. Just sliding your finger on the touchpad doesn't seem to work anymore.

    I installed xserver-xorg-input-synaptics but nothing...

    Anyone else seen this? It works fine with a mouse plugged into it, but, I can't stand when something doesn't work right.

    Re: Touchpad only wor

    To list all device's use:
    This is how mine shows:
    xinput list
    ⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
    ⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
    ⎜   ↳ Logitech K780                           	id=9	[slave  pointer  (2)]
    ⎜   ↳ SynPS/2 Synaptics TouchPad              	id=12	[slave  pointer  (2)]
    ⎜   ↳ TPPS/2 IBM TrackPoint                   	id=13	[slave  pointer  (2)]
    ⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
        ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
        ↳ Power Button                            	id=6	[slave  keyboard (3)]
        ↳ Video Bus                               	id=7	[slave  keyboard (3)]
        ↳ Sleep Button                            	id=8	[slave  keyboard (3)]
        ↳ Integrated Camera: Integrated C         	id=10	[slave  keyboard (3)]
        ↳ AT Translated Set 2 keyboard            	id=11	[slave  keyboard (3)]
        ↳ ThinkPad Extra Buttons                  	id=14	[slave  keyboard (3)]
        ↳ Logitech K780                           	id=15	[slave  keyboard (3)]
    Ubuntu 18.04 comes with libinput touchpad driver by default and the OS is missing Synaptics touchpad driver.
    To see if installed use:
    apt policy xserver-xorg-input-synaptics
    if it shows as not installed use:
    sudo apt install xserver-xorg-input-synaptics
    EDIT: Sorry I just flat missed this: "I installed xserver-xorg-input-synaptics but nothing...

    Sorry if this sounds strange, but there is a keyboard combination to turn the touchpad off.
    Happened to me as well haha
