Hey guys, very new to linux. Have a acer c7 chromebook running ubuntu 12.04. Wacom graphics tablet in settings shows "tablet not detected". Any help will be greatly appreciated.

Hi gnr609,

Welcome to Ubuntu forums!


So you installed Ubuntu Precise 12.04 on your Chromebook?

Run the following commands in a terminal with the Intuos4 plugged in and post the output.

lsusb
and
xinput list

Hey Favux, thx for the quick reply. Yeah followed some instructions from google and installed ubuntu.
Everything seems to be running fine but this is the first problem I ran into. This is what I get:

Alright, it is showing up in lsusb but not xinput list. Let's check if the Wacom usb kernel driver/module wacom.ko is auto-loading.

lsmod | grep [Ww]acom

What's the output?

[gnr609]

I don't seem to be getting anything

user@ChrUbuntu:~$ lsmod | grep [Ww]acom
user@ChrUbuntu:~$ lsmod | grep wacom
user@ChrUbuntu:~$ lsmod | grep Wacom
user@ChrUbuntu:~$

[Favux]

To "force" the module to auto-load add wacom to the bottom of the list of modules in the modules file at /etc/modules.

gksudo gedit /etc/modules

Should end up looking something like:

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

lp
rtc
wacom

[gnr609]

Ok, after running gksudo gedit /etc/modules, a modules(/etc)-gedit window opens up showing

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.


lp
rtc

do I just type wacom on the bottom and save?
sorry for the newbness, its my first experience with linux.

[Favux]

do I just type wacom on the bottom and save?

Yes.

Then restart.

[gnr609]

Ok, saved and restarted. Im still not getting any output when I run "lsmod | grep [Ww]acom"
wacom does show on the bottom of the list when I run " gksudo gedit /etc/modules"

[Favux]

OK, now we need to check if wacom.ko is present on your system. It should be located in this directory:

/lib/modules/`uname -r`/kernel/drivers/input/tablet/wacom.ko

Where `uname -r` is kernel version you are running currently. There should be other modules in the tablet directory other than wacom.ko. Is it there?
