Giving as much information as I can, please ask if missed anything as first bug submission.
Symptoms: trackpad 'locks' in scrolling mode (cannot move mouse cursor, track-pad presumes scrolling gesture). No pattern to the cause can yet be identified.
Syslog reveals:
kernel: [19127.694447] thinkpad_acpi: unknown possible thermal alarm or keyboard event received
kernel: [19127.694454] thinkpad_acpi: unhandled HKEY event 0x6060
kernel: [19127.694456] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx
acpid: client 1124[0:0] has disconnected
acpid: client connected from 1124[0:0]
acpid: 1 client rule loaded
Temporal fix:
Switching to another terminal via Ctrl+Alt+F1 and back to graphical mode returns the trackpad to normal operation.
The system model is 'Lenovo E520 1143'. Please find lshw attached if helpful.
Kind regards,
Chris
