Title:
Problems with Lenovo input devices (keyboard & touchpad)
Status in linux package in Ubuntu:
Incomplete
Bug description:
My Lenovo ideapad 700-15ISK repeatedly outputs the character '^@'
about twice per second while in a tty. This interferes with the
functionality of the keyboard (the "repeat keys" feature is quickly
interrupted and stopped). Though the '^@' does not print in Unity, the
effects are the same. I can login to Unity fine, but typing passwords
is impossible in a tty.
Additionally, enabled Synaptics touchpad features simply don't work,
including two-finger scrolling and tap to click.
This problem began after upgrading to the first 4.13 kernel. Reverting
to kernel 4.11 fixes these issues, and so does installing the mainline
kernel (v4.16-rc7).
