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:
# rmmod wacom && modprobe wacom && dmesg | tail -n 11
