Title:
'SynPS/2 Synaptics TouchPad' doesn't work 'Lenovo Thinkpad T440p'
after the kernel upgrade
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hi all,
I have been using Xubuntu 16.04 since June 2016 on my Lenovo Thinkpad T440p
(i5-4210M, 16GB RAM, NVIDIA 730M). However since last year (probably after a
kernel upgrade), my touchpad has stopped working (I always keep the system
upgraded via apt update/upgrade. It doesn't work at all, and I have to use an
external mouse. As per the description at
https://wiki.ubuntu.com/DebuggingTouchpadDetection,
Only very rarely, it somehow works as well (by rare I mean twice in the last
two years), but as soon as I reboot, the state is back to non-working at all.
I attach an archive touchpad_debug.tar.gz containing two sub-folders
working_state and nonworking_state. Each folder contains the dmesg
output, my /proc/bus/input/devices, and my /var/log/Xorg.0.log when
the touchpad was working and not working. In working_state, I
additionally have the outputs to "xmodmap -pp", "xinput --list ", and
"xinput --list-props <id>".
Regards,
Omer
