[SOLVED] Touch screen stopped working on Thinkapd X1 Yoga 4th gen

Few days ago I noticed that the touch screen stopped working. The Stylus pen works fine.
Actions I tried and didn't solve the issue:

  • Checked on both kernel ver 6.5.7 and LTS 6.1.58

  • Added user to input and plugdev groups (wasn't required before but /dev/hidraw* belongs to plugdev and /dev/input/event* belogns to input)

  • Updated using libwacom-update-db

  • Loaded input-wacom-dkms driver instead

The only hint I can see occasionally in dmesg is:

wacom_idleprox_timeout: tool appears to be hung in-prox. forcing it out.

Device seems discovered:

# libwacom-list-local-devices                                                                                                                                                  [0]
devices:
- name: 'ISDv4 51B7'
  bus: 'usb'
  vid: '0x056a'
  pid: '0x51b7'
  nodes: 
  - /dev/input/event6: 'Wacom Pen and multitouch sensor Pen'
  - /dev/input/event5: 'Wacom Pen and multitouch sensor Finger'

Module seems to load fine:

It's started to work again without any known change I made.
