[Bug 1156314] Re: Lenovo U300s Trackpad detected as PS/2 Generic Mouse

 

Tim Pennucci, as per
http://support.lenovo.com/en_US/downloads/default.page? an update is
available for your BIOS (56cn38ww). If you update to this, does it
change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

Title:
  [Lenovo IdeaPad U300s] Trackpad detected as PS/2 Generic Mouse

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  My Lenovo U300s Trackpad usually does not work (anymore).  Sometimes it has full functionality, and all of a sudden it will not cease responding to any input, and I cannot correlate these events to anything.  I see that the trackpad is detected as a PS/2 Generic Mouse in these cases.  The problem does not solve itself on reboot, but seems to solve itself at random.  The duty cycle of the problem's occurance has increased from maybe 10% to 80% of the time I use the laptop.  Using an external mouse is a hassle.   Attached are outputs and files from:
  dmesg
  /proc/bus/input/devices
  /var/log/Xorg.0.log
  /proc/version_signature
  lspci -vnvn
  lsb_release -rd
  apt-cache policy linux

  Please, please advise.  Thank you.
