HOWTO Wacom bamboo CTL-460 in Lucid Lynx

[Favux]

Hi [mag],

Welcome to Ubuntu forums!

My guess is that you had a kernel update. That will knock out a compiled wacom.ko because the new kernel has a new modules directory that the compiled wacom.ko isn't in. So you can first try copying the compiled wacom.ko from the unpacked linuxwacom tar you used into place and if that fails recompile. To tell what kernel you have in a terminal enter:

cat /proc/version_signature

That will get the last little suffix which can distinguish versions.

I'm not sure why your compiles aren't working. Any errors? Since 0.8.6-1 isn't available any longer you should be using 0.8.6-2, which was also the first version to be Xserver version aware. In other words you no longer have to do the extra directory change with 0.8.6-2 (and up) like you did with 0.8.6-1. Could that be why it isn't working? Maybe if you aren't doing the extra directory change you're still using the modified copy command for the extra directory change instead of the normal one?:

sudo cp ./src/2.6.30/wacom.ko /lib/modules/`uname -r`/kernel/drivers/input/tablet/wacom.ko

Update: I got it working! See below.

Welcome to Ubuntu forums!

Thanks

My version signature is "Ubuntu 2.6.32-22.36-generic 2.6.32.11+drm33.2". Also, my architecture is x86-64.

I'm not sure why your compiles aren't working. Any errors?

No errors, as far as I can tell. For all I know, this might not be a problem with wacom.ko at all.

sudo cp ./src/2.6.30/wacom.ko /lib/modules/`uname -r`/kernel/drivers/input/tablet/wacom.ko

So... is that the cp-command I am supposed to use? In that case I am using the correct one.

I've attached a dump of the terminal with the whole procedure. Maybe there's something there.

I do, however, get some errors in my /var/log/Xorg.0.log when plugging the Bamboo:

I don't understand why there is a problem, though. My wacom_drv should be up to date, since I just did:

sudo apt-get purge xserver-xorg-input-wacom
sudo apt-get install xserver-xorg-input-wacom xserver-xorg-input-all

Update: Apparently, this reinstall of xserver-xorg-input-wacom was exactly what I needed. But I also needed to restart X afterwards to get it working. I have no idea what messed up my wacom_drv.so, though.

Outstanding!

I have no idea what messed up my wacom_drv.so, though.

Probably will remain a mystery. Presumably something to do with the update, hopefully not a disk or RAM problem.

But I also needed to restart X afterwards to get it working.

Right, that's why after copying the wacom.ko into place and doing:

sudo depmod -a

I recommend rebooting. I know you shouldn't have to but for whatever reason it seems to work better. Otherwise there's a few that don't get the driver working.

Thank you for your quick responses! Keep up the good work

Yeah, hi guys. The above method works, but after installing the driver, the pen acted weird. The mouse moves when I move my pen across the tablet, but would suddenly stop whenever I click something on the screen. Then it takes a while for it to be working again, and same thing happens every time I click on the screen. Anyone know what's wrong?

Hi opensource-for-all,

Check that the wacom drivers actually have your tablet by checking Xorg.0.log in /var/log. It may be another driver like evdev.


Hi thunderdan,

Linuxwacom 0.8.6 is no longer posted at the LWP site. You want 0.8.6-2. See post #1077 abstracted from the linuxwacom HOW TO.

[thunderdan]

Thanks, Favux. I got 0.8.6-2. Now I'm to this part:

daniel@daniel-desktop:~/linuxwacom-0.8.6-2/src/2.6.30$ sudo cp wacom.ko /lib/modules/'uname -r'/kernel/drivers/input/tablet
[sudo] password for daniel: 
cp: cannot create regular file `/lib/modules/uname -r/kernel/drivers/input/tablet': No such file or directory

Hi thunderdan,

Can you tell me a little more about your system? What release/kernel are you on, etc.? And why did you make the directory change to /src/2.6.30? Did you compile in that directory?

Hi thunderdan,

Can you tell me a little more about your system? What release/kernel are you on, etc.? And why did you make the directory change to /src/2.6.30? Did you compile in that directory?

The release is lucid. The kernel is 2.6.32-22-generic. I changed directory to /src/2.6.30 because the first post of this thread said:

tar -xf linuxwacom-0.8.6.tar.bz2
cd linuxwacom-0.8.6
./configure --enable-wacom
cd src/2.6.30/

I'm not sure if I compiled in that directory or not. "make" is the command to compile, right? If so, then yes, I did compile in that directory.

But I noticed one thing I did wrong. I used ' instead of ` when typing `uname -r`. I just tried it with the correct ` and got no error message. Now when I moved on to the next line:

daniel@daniel-desktop:~/linuxwacom-0.8.6-2/src/2.6.30$ sudo rmmod wacom
ERROR: Module wacom does not exist in /proc/modules
