Public bug reported:
While I was trying to install Ubuntu 16.04 LTS, the grub-installer-amd64
crushed
ProblemType: Bug
DistroRelease: Ubuntu 16.04
Package: ubiquity 2.21.63.4 [modified:
lib/partman/automatically_partition/question]
ProcVersionSignature: Ubuntu 4.10.0-28.32~16.04.2-generic 4.10.1
I got it to work on thinkpad T420 by using
sudo xinput set-int-prop 11 "Synaptics Off" 8 0
the bug happens because there are two properties governing the touchpad "on"
status "device Enabled" and "Synaptics Off" and they must be set to 1 and 0
respectively if the touchpad is to work the problem
