X Error: BadDevice, invalid or uninitialized input device 168

[sup]

sometimes, when I start applications from terminal (opera, for example), I got this:

X Error: BadDevice, invalid or uninitialized input device 168
  Major opcode:  148
  Minor opcode:  3
  Resource id:  0x0
Failed to open device
X Error: BadDevice, invalid or uninitialized input device 168
  Major opcode:  148
  Minor opcode:  3
  Resource id:  0x0
Failed to open device

it does not seem to cause any troubles, but I wonder, what it means, any ideas? I tried to google it but without much succes

I just got it loading kcmshell fonts.

I figured out on some other threads that this is most likely due to some "wacom" devices in your xorg.conf. Be sure to comment them out in your xorg.conf (there were three such devices in mine). Also be sure to comment out the references to them in the ServerLayout section (one reference to each), otherwise X won't start up again. Here are the sections commented out:

# 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

. . . and much farther down:

Section "ServerLayout"
        Identifier      "Default Layout"
        Screen          "Default Screen"
        InputDevice     "Generic Keyboard"
        InputDevice     "Configured Mouse"
#       InputDevice     "stylus" "SendCoreEvents"
#       InputDevice     "cursor" "SendCoreEvents"
#       InputDevice     "eraser" "SendCoreEvents"
EndSection

I see that did the trick, thanks.

Thanks! I was having the same problem, and this fixed it. Much obliged!

Regarding the wacom thing, any reason why they are enabled by default in Xorg.conf?
These errors confused the hell out of me, I wonder what they would have done to a new user.
Surely it isn't too much to ask to confirm during installation if the user has any wacom tablets or what not?

Sorry i'm new to kubuntu and need some help.

i used kate /etc/X11/xorg.conf to open the file and make the changes. however, it won't let me save, something about write privileges i think.

i type su to login as root, and to my surprise i don't even have the password to root. i thought that the default login i make was the root.
what do i do now? i still have this problem, and its stopping me from using automatix and other programs.

You need to use sudo, i.e. sudo kate /etc/X11/xorg.conf, it will prompt you for YOUR (not root's) password and then it will be possible to save it.
If you want to make graphical launcher, use gksudo, if you want to havbe root's terminal, type sudo su (Et least I think it is this command)... there is a way to enable root's account (su passwd maybe, i do not remember, search wiki for root account or something and you should find your way, this is very common question to newbies), but it is not recommended - and I think it is right since sudo works so nicely.

[rand0m3r]

this is a bit weird.

i thought sudo was just su but only applied for a single command. hence the password for sudo and su should be the same. anyway i did sudo kate /etc/X11/xorg.conf and made those changes. the error msgs still pop-up, but everything seems to work now.

Make sence to disable the Tablet things in the conf file. didn't think of that before.
