[Bug 1432413] Re: Synaptic Touchpad xevents are hijacked under X

 

I have now tried to get 15.04 up and working properly on a new disk but
did not succeed and I have no intention being part of troubleshooting
problems with 15.04 since I plan on staying on 14.04 for at least two
more years.

I do want to help troubleshooting this problem and I have nothing
against applying patches or building test kernels/drivers or whatever as
long we can get the synaptic touchpad to be fully usable.

Title:
  Synaptic Touchpad xevents are hijacked under X

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  Synaptic Touchpad xevents are hijacked under X11.

  I have a problem with the synaptic touch-pad on my Acer Aspire that started around a week ago.
  The problem can be described as that there is a massive amount of xevents being generated and appearing to originate from the touch-pad even though the touch-pad is not used.
  I have tested the HW which seems to work fine.
  The test performed is to start a terminal session (Ctrl + Alt + 2) before the fault occurs and check the xevents by running
   ~$ sudo evtest /dev/input/eventX
  where the X to use is found in /proc/bus/input/devices and found by running
   ~$ cat /proc/bus/input/devices |grep mouse
  No matter how much the touch-pad is used will the console show the corresponding events which indicates that HW and driver works OK as long it is not under X

  When the problem has occurred (in Desktop mode) is it easy (but inconvenient) to get back to normal by key combo Fn+F7 twice, turn off touch-pad and then turn on again.
  And more, one can get unlucky in the sense that the generated events could click somewhere one do not want to click.
  During the problem is it impossible to use the mouse since it flies around (mostly going in a bottom to top of screen direction) but one can check the generated events using evtest again.

  How can I help troubleshooting the problem?
