current mouse/touchpad settings dialog
Description of problem:
I am not sure if the libtpms or tpm_crb is the right component or not.
When booting my Fedora 23 Workstation client, the touchpad works but lacks the necessary settings to control sensitivity, scrolling, or any other features.
My laptop is a (new) Dell Inspiron 13-7353.
Processor: Intel® Core™ i7-6500U CPU @ 2.50GHz × 4
Graphics: Gallium 0.4 on llvmpipe (LLVM 3.7, 256 bits)
Linux mali 4.2.6-301.fc23.x86_64 #1 SMP Fri Nov 20 22:22:41 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Version-Release number of selected component (if applicable):
Booting up my laptop.
Steps to Reproduce:
Touchpad works, but touch to click is turned on making typing a pain since the sensitivity is set rather high. No options for disabling this, two finger scrolling, etc.

I doubt that either libtpms (TPM emulator) or the TPM CRQ driver have any influence on the sensitivity of the touch pad. I am removing libtpms as being a source of the error.
can i provide any more data that might be the answer to this?

This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
