Ubuntu – restarting thesterious touchpad driver in 19.10

19.10driversmousetouchpad

I got a new laptop for Christmas, and it's full of new hardware, so my only option was to install ubuntu 19.10, but among the bugs I've been facing, my touchpad seems to 'freeze up' whenever I have to wake my computer up from sleep, but I still can't figure out how to restart my mouse pad driver, I followed several different sets of instructions from Is there a way to "restart" the touchpad driver? but to no avail

I'm sure the sudo modprobe -r drivername && sudo modprobe drivername would work, but I can't seem to find the driver for my touchpad.

using xinput --list returns

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Logitech Wireless Mouse                   id=9    [slave  pointer  (2)]
⎜   ↳ ELAN Touchscreen                          id=10   [slave  pointer  (2)]
⎜   ↳ MSFT0002:01 04F3:304B Touchpad            id=12   [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)]
    ↳ Power Button                              id=8    [slave  keyboard (3)]
    ↳ Integrated Camera: Integrated C           id=11   [slave  keyboard (3)]
    ↳ Ideapad extra buttons                     id=13   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=14   [slave  keyboard (3)]

using xinput disable 12 && xinput enable 12 yields no help.

using grep -iA2 touchpad /proc/bus/input/devices yields:

N: Name="MSFT0002:01 04F3:304B Touchpad"
P: Phys=i2c-MSFT0002:01
S: Sysfs=/devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-1/i2c-MSFT0002:01/0018:04F3:304B.0001/input/input23

which indicates that designware is the driver? But using ls $(find /lib/modules/$(uname -r) -type d -name mouse) doesn't show any such driver name:

appletouch.ko  bcm5974.ko  cyapatp.ko  elan_i2c.ko  gpio_mouse.ko  psmouse.ko  sermouse.ko  synaptics_i2c.ko  synaptics_usb.ko  vsxxxaa.ko

I've gone through and systematically restarted each one and none of them seem to be helping, is there somewhere else that a mouse driver would be located that I can look in?

The laptop model I'm using is:

Lenovo IdeaPad S340


Edit

I found a different question from a different forum https://unix.stackexchange.com/questions/423797/how-do-i-disable-i2c-designware-support-when-its-not-built-as-a-module that seems to address a similar issue concerning the built-in designware driver, how do I restart the designware driver, if as the link says, "It's not built as a module"?

Best Answer

Assuming you have these:

xserver-xorg-input-libinput 
xserver-xorg-input-evdev 
xserver-xorg-input-mouse

(if you don't sudo apt install xserver-xorg-input-libinput xserver-xorg-input-evdev xserver-xorg-input-mouse) You might have to install this: xserver-xorg-input-synaptics
sudo apt install xserver-xorg-input-synaptics
