Wacom Device falsely detected in xorg.conf

[Stéphane Marguet]

Binary package hint: xorg

On Edgy, a lot of xorg.conf files include wacom device that doesn't exist.
In my xorg.conf (ati 9600) :

Section "InputDevice"
  Driver "wacom"
  Identifier "stylus"
  Option "Device" "/dev/wacom"
  Option "Type" "stylus"
  Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection
Section "InputDevice"
  Driver "wacom"
  Identifier "eraser"
  Option "Device" "/dev/wacom"
  Option "Type" "eraser"
  Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection
Section "InputDevice"
  Driver "wacom"
  Identifier "cursor"
  Option "Device" "/dev/wacom"
  Option "Type" "cursor"
  Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection

It's not very important as it is working anyway but it's creating errors in log files.

See Bug https://launchpad.net/bugs/73572 for the xorg.conf generated by Xorg -configure.
No wacom devices detected.

same issue in feisty herd 4. must we punish the masses whilst we work out the wacom stuff? not only is it cluttering up local log files, but it's also cluttering up other bug reports, forums and google searches with lines such as

X Error: BadDevice, invalid or uninitialized input device 167
  Major opcode: 144
  Minor opcode: 3
  Resource id: 0x0
Failed to open device
X Error: BadDevice, invalid or uninitialized input device 167
  Major opcode: 144
  Minor opcode: 3
  Resource id: 0x0
Failed to open device

since Xorg -configure finds no wacom devices this appears to be a fault in the installation scripts that generate the initial xorg.conf.

is this just a k/ubuntu deal or does it need to go upstream?

attached is more info and a workaround for those without wacom devices

[Stéphane Marguet (stemp)]

Fuggum, the upstream bug was rejected because Xorg -configure work well.
It's a K/Ubuntu script problem.
From Daniel Stone :
«This is part of the xorg.conf generator in Ubuntu; please file a bug in
Launchpad. It will likely get rejected, however, if the only reasoning is
cosmetic ...»

maybe we can do something about it for feisty, no guarantees though..

mind you, the entries are totally harmless even if you don't have (a) wacom device(s)
