Hi gabryzen,

Welcom to Ubuntu forums!

What release of Ubuntu are you using? In other words what is the kernel?

uname -r

[taeksosin]

If it's necessary to split off into a new thread, someone just let me know. Have a Dell Mini 10v running Ubuntu 10.04 LTS. Current version of kernel is 2.6.32-33-generic. I've followed the guide in appendix 3 from http://ubuntuforums.org/showthread.php?t=1515562 . I get the following output when I attempt to make the file.

I'm a linux newb, completely at a loss to figure out exactly what it's saying. Near as I can tell, I'm missing lunix/input/mt.h, but I'd figured that'd be covered by running the updates/upgrades and what not. Anyone have any recommendations?

Hi taeksosin,

You're fine on this thread. You have that right, the mt.h (multi-touch header) is missing. Lucid's (10.04) 2.6.32 kernel doesn't have it. As far as I know Natty's 2.6.38 kernel is the first to have it. Maybe it appears in .37 or something but I know Maverick's 2.6.35 doesn't have it either.

If you have a Pen/Connect (the DD, lsusb in a terminal) then all you need is the stylus working. We can probably do that by patching input-wacom. If you have one of the other models with touch, you won't be able to get touch working without 2.6.38 or higher.

[taeksosin]

Favux,

You're right on the money with the Bamboo type. It's the Bamboo Connect CTL 470/k, and all I care about is pen functionality. How would I go about patching input-wacom?

Just a wee bit of background, I have 30 some odd units in a school computer lab that this is for. Infecting 450ish K-8 kids per year with opensource as best as I can, and GIMP + Bamboo I think is going to be a winning combination.

Nice project. Sounds like a good way to expose the students to OSS.

The line #'s in the following assume your cloning input-wacom (appendix 2) but it should work with input-wacom-0.11.1 also. Either way once you have the uncompressed input-wacom source code folder you're set. In the wacom_wac.c file in the 2.6.30 folder in the input-wacom folder add:

static const struct wacom_features wacom_features_0xDD =
        { "Wacom Bamboo Connect", WACOM_PKGLEN_BBFUN,     14720,  9200, 1023, 63, BAMBOO_PT };

between:

static const struct wacom_features wacom_features_0xDB =
	{ "Wacom Bamboo 2FG 6x8 SE", WACOM_PKGLEN_BBFUN,  21648, 13700, 1023, 63, BAMBOO_PT };
static const struct wacom_features wacom_features_0x20 =
	{ "Wacom Intuos 4x5",     WACOM_PKGLEN_INTUOS,    12700, 10600, 1023, 31, INTUOS };

At about line #1342 so it looks like:

static const struct wacom_features wacom_features_0xDB =
	{ "Wacom Bamboo 2FG 6x8 SE", WACOM_PKGLEN_BBFUN,  21648, 13700, 1023, 63, BAMBOO_PT };
static const struct wacom_features wacom_features_0xDD =
        { "Wacom Bamboo Connect", WACOM_PKGLEN_BBFUN,     14720,  9200, 1023, 63, BAMBOO_PT };
static const struct wacom_features wacom_features_0x20 =
	{ "Wacom Intuos 4x5",     WACOM_PKGLEN_INTUOS,    12700, 10600, 1023, 31, INTUOS };

And add:

	{ USB_DEVICE_WACOM(0xDD) },

between:

	{ USB_DEVICE_WACOM(0xDB) },
	{ USB_DEVICE_WACOM(0x41) },

At about line #1512 so it looks like:

	{ USB_DEVICE_WACOM(0xDB) },
	{ USB_DEVICE_WACOM(0xDD) },
	{ USB_DEVICE_WACOM(0x41) },

Then go on to compile as instructed.

To avoid patching xf86-input-wacom's wcmUSB.c if you have the Lucid default xf86-input-wacom-0.10.5 go ahead and update that as in part II.

Sorry about the delay on trying this, hadn't had time to play with it. Getting an error when I attempt to compile after following the steps in Appendix 2. I made the changes to the necessary file, get the following when I go and try to run autogen.sh. It LOOKS like it has an issue with the second bit of code you had me add in, is there something additional I need to change? Output from autogen.sh below.

Hi Favux,

Thank you very much for your help, I have learned much from your posts. However I have the exact same problem as taeksosin. I have a CTL-470/K an I am in 2.6.32 for reasons out of my control. I undertand the mt.h is designed for a more advanced kernerl but this tablet is very simplistic and doesn't have touch functions or anything fancy, just need the stylus working.

I tried changing the lines of the wacom_wac.c as you suggested. I did it in input-wacom-0.11.1 AND in the version from git in appendix #2 and got the same error when configuring :

/home/teacher/Desktop/input-wacom/2.6.30/wacom_wac.c:1343: error: 'WACOM_PKGLEN_BBPEN' undeclared here (not in a function)

I went to the file wacom_wac.h and added the line "#define WACOM_PKGLEN_BBPEN 10" to define BBPEN just on top of the stylus ang it finally compiled.I copied de wacom.ko and everything else you mentioned in the appendix.

After trying all this , the tablet doesn't want to work.

Any thoughts? Am I doing something wrong with this patch?

Thanks in advance Favux...

Hi taeksosin and thrischan,

Sorry my mistake. I used the wrong variable. It should have been WACOM_PKGLEN_BBFUN and not the more recent WACOM_PKGLEN_BBPEN. I'll fix the instructions in post #15.

[thrischan]

Hi Favux,

Thank you for you quick response. I fixed the file but still, the CTL-470/K is not working.

I also tried PART II to manually compile xf86-input-wacom-0.11.x and nothing.

My Xorg information is the following, ( I updated Xorg from a untable repository for no reason other than just than trying to solve this problem ) so I don't know if the problem could be this :

X.Org X Server 1.11.1.902 (1.11.2 RC 2)

xorg-server 2:1.11.1.902-1 (Cyril Brulebois <kibi@debian.org>)

Should I install a fresh copy of my system to get rid of this unstable Xorg that is spread all over my system? and try again? Or is there something I am not aware of?

Thanks in advance!

[Favux]

Hi thrischan,

So this time it compiled without an error?

My inclination is to blame the problem on your new Xorg. But before you nuke it what configuration file are you using? I imagine instead of 10-wacom.conf in /usr/lib/X11/xorg.conf.d for that X server you would need a 50-wacom.conf located in /usr/share/X11/xorg.conf.d. Is that what you have?
