Title:
ideapad yoga needs psmouse reload
Status in linux package in Ubuntu:
Triaged
Bug description:
So, my often made fun of, lenovo ideapad yoga, since sometime in the
14.10 development cycle needs an extra help to get the trackpad
working.
On boot the mouse pointer is not visible.
If I open terminal and do "rmmod psmouse; modprobe psmouse" the
pointer magically appears on first touch.
Please help me as to how I can bisect / track down what the issue here
is. Sometime in the past it was working reliably.
