[Bug 46854] Re: KDE mouse control fails to set touchpad for left-handed operation

[Chip Rosenthal]

** Description changed:

  Binary package hint: kcontrol
  
  Environment is:
  * Dell Inspiron 600m
  * AlpsPS/2 Glidepoint touchpad
  * Ubuntu Dapper
  * KDE desktop
  * kcontrol 3.5.2-0ubuntu26
  
  Perform: System Settings -> Mouse -> Left handed -> apply
  
  This does not have any effect on the touchpad button order (i.e. button
- 1 remains the right button).
+ 1 remains the left button).
  
  The Gnome control panel works correctly, the touchpad buttons can be
  remapped.
  
  Also ... in previous versions of Ubuntu, the Alps Glidepoint appeared as
  a 12-button mouse to X, and I could remap the touchpad for left-handed
  use by saying:
  
  xmodmap -e 'pointer = 3 2 1 4 5 6 7 8 9 10 11 12'
  
  Now when I try that I get an error:
  
  xmodmap:  commandline:1:  bad number of buttons, must have 9 instead of 12
  xmodmap:  1 error encountered, aborting.
  
  I have a guess at what is causing the xmodmap behavior ... in previous
  releases I set touchpad as my CorePointer and did not configure any
  other pointing devices.
  
  In the default Dapper installation the PS/2 port (currently empty) is
  set as the CorePointer, and I suspect xmodmap may be trying to
  reconfigure that.  Maybe kcontrol is doing the same???
