Strange behaviour

[Renaud (Ron) Olgiati]

On a freshly installed 6.06 Kubuntu:

When I start a graphical app from the konsole, I get the following error 
messages in the console before the prog starts:

X Error: BadDevice, invalid or uninitialized input device 166
  Major opcode:  144
  Minor opcode:  3
  Resource id:  0x0
Failed to open device
X Error: BadDevice, invalid or uninitialized input device 166
  Major opcode:  144
  Minor opcode:  3
  Resource id:  0x0
Failed to open device

I had a look in /etc/X11/xorg.conf where I was surprised to fid the following, 
given I have a bog-standard keyboard and (serial) mouse, but nothing like 
those:

Section "InputDevice"
  Driver "wacom"
  Identifier "stylus"
  option "Device" "/dev/wacom"# Change to 
  option "Type" "stylus"
  option "ForceDevice" "ISDV4"# Tablet PC ONLY
  # /dev/input/event
  # for USB
EndSection

Section "InputDevice"
  Driver "wacom"
  Identifier "eraser"
  option "Device" "/dev/wacom"# Change to 
  option "Type" "eraser"
  option "ForceDevice" "ISDV4"# Tablet PC ONLY
  # /dev/input/event
  # for USB
EndSection

Section "InputDevice"
  Driver "wacom"
  Identifier "cursor"
  option "Device" "/dev/wacom"# Change to 
  option "Type" "cursor"
  option "ForceDevice" "ISDV4"# Tablet PC ONLY
  # /dev/input/event
  # for USB
EndSection

Would these devices be the cause of the error messages I am getting ?

Can I remove those entries, or is there a risk of finding myself without X11 ?

TIA,
 
Ron.
