How to restart Wacom driver without restarting computer on Linux

I have a Lenovo Thinkpad Yoga 370 with the Lenovo ThinkPad Pen Pro 2.

While I’m writing using Xournal++, sometimes the pen suddenly stops working.

I find a way to make it work again without restarting my computer.

First, we have to find the device name of the wacom digitizer:

# lsmod|grep wacom
wacom                 118784  0
usbhid                 57344  2 wacom,hid_uclogic
hid                   131072  7 i2c_hid,wacom,usbhid,hid_uclogic,hid_sensor_hub,intel_ishtp_hid,hid_generic

On my computer the device is “wacom”. So I can simply restart the wacom driver like this:

sudo modprobe --remove wacom ; sudo modprobe wacom

To make that happening less often, we can configure Xournal++ like that:

We can find xinput device name with this command:

# xinput list
⎡ Virtual core pointer                     id=2 [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer               id=4 [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=11 [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard             id=12 [slave  keyboard (3)]
    ↳ ThinkPad Extra Buttons                   id=15 [slave  keyboard (3)]
    ↳ 2.4G Mouse System Control                id=17 [slave  keyboard (3)]
    ↳ 2.4G Mouse                               id=18 [slave  keyboard (3)]
    ↳ 2.4G Mouse Consumer Control              id=20 [slave  keyboard (3)]

On my computer the xinput device name is “Wacom Pen and multitouch sensor Pen stylus”. So I use these 2 commands in Xournal++ :

xinput enable "Wacom Pen and multitouch sensor Finger touch"
xinput disable "Wacom Pen and multitouch sensor Finger touch"

Hope it’ll help someone.
