Hver eneste gang, jeg starter en grafisk applikation i KDE fra et terminal-vindue, får jeg denne fejl:
<pre>
X Error: BadDevice, invalid or uninitialized input device 166
Major opcode: 144
Minor opcode: 3
Resource id: 0x0
Failed to open device
</pre>
Det viser sig, at fejlen er relateret til et eller andet apparat som er på nogle tablet-pc'ere. Af en eller anden grund, er @/etc/X11/xorg.conf@ i Kubuntu som standard sat op så denne dims skal bruges, hvis den findes. Man får så fejlen, hvis den ikke findes.
En løsning på problemet er at udkommentere de linier i @/etc/X11/xorg.conf@ som nævner udstyr til tablet-pc'ere, hvis du ikke bruger en tablet-pc.
Ã…bn @/etc/X11/xorg.conf@ og find linierne:
<pre>
Section "InputDevice"
Driver "wacom"
Identifier "stylus"
Option "Device" "/dev/wacom" # Change to
# /dev/input/event
# for USB
Option "Type" "stylus"
Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection
Section "InputDevice"
Driver "wacom"
Identifier "eraser"
Option "Device" "/dev/wacom" # Change to
# /dev/input/event
# for USB
Option "Type" "eraser"
Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection
Section "InputDevice"
Driver "wacom"
Identifier "cursor"
Option "Device" "/dev/wacom" # Change to
# /dev/input/event
# for USB
Option "Type" "cursor"
Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection
</pre>
og erstat dem med:
<pre>
#Section "InputDevice"
# Driver "wacom"
# Identifier "stylus"
# Option "Device" "/dev/wacom" # Change to
# # /dev/input/event
# # for USB
# Option "Type" "stylus"
# Option "ForceDevice" "ISDV4" # Tablet PC ONLY
#EndSection
#
#Section "InputDevice"
# Driver "wacom"
# Identifier "eraser"
# Option "Device" "/dev/wacom" # Change to
# # /dev/input/event
# # for USB
# Option "Type" "eraser"
# Option "ForceDevice" "ISDV4" # Tablet PC ONLY
#EndSection
#
#Section "InputDevice"
# Driver "wacom"
# Identifier "cursor"
# Option "Device" "/dev/wacom" # Change to
# # /dev/input/event
# # for USB
# Option "Type" "cursor"
# Option "ForceDevice" "ISDV4" # Tablet PC ONLY
#EndSection
</pre>
Find derefter sektionen @ServerLayout@ og fjern dem derfra.
<pre>
Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "Generic Keyboard"
InputDevice "Configured Mouse"
InputDevice "stylus" "SendCoreEvents"
InputDevice "cursor" "SendCoreEvents"
InputDevice "eraser" "SendCoreEvents"
InputDevice "Synaptics Touchpad"
EndSection
</pre>
bliver til:
<pre>
Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "Generic Keyboard"
InputDevice "Configured Mouse"
#InputDevice "stylus" "SendCoreEvents"
#InputDevice "cursor" "SendCoreEvents"
#InputDevice "eraser" "SendCoreEvents"
InputDevice "Synaptics Touchpad"
EndSection
</pre>
Det gjorde i hvert fald tricket for mig. Nu får jeg ikke den grimme fejlbesked mere. :)
