[Bug 1437755] Re: Touchpad incorrectly detected as PS/2 mouse in 'ASUS PU551L'


David Zafra Gómez, thank you for reporting this and helping make Ubuntu
better. As per
an update to your computer's buggy and outdated BIOS is available (208).
If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, 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

For more on BIOS updates and linux, please see

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then
please mark this report Status Confirmed.

Thank you for your understanding.

   Touchpad incorrectly detected as PS/2 mouse in 'ASUS PU551L'

Status in linux package in Ubuntu:

Bug description:
  As I've just red here
  https://wiki.ubuntu.com/DebuggingTouchpadDetection, I'm sending you
  this information. My case fits with what is described in "In case
  Touchpad features like scrolling, tapping, etc. do not work at all.",
  that is, I can't find the 'Touchpad' tab in System -> Preferences ->
  Mouse. Also, the touchpad acts just like a mouse, and I can't disable

  I've attached devices text file as suggested in the link above, but I
  haven't been able to attach xinput and Xorg.0.log files because I just
  can't attach one file.

  Thanks for dealing with my case.
