I discovered the fatdog 610 distro has wacom already pre-installed.

The applications just have to be set for pressure in their preferences Laughing

Porteus linux and Ubuntu are the same .

Don570 and Charlie6,

Puppy 5.2.8 uses the 2.6.33.2 kernel and the 1.7.6 X server which turns out to be an in-between combination relating to the Linux Wacom project and its support for stand-alone serial tablets, specifically the Protocol 4 models. By 'in-between' I mean that their Xorg driver for v1.7.6 does not work with their kernel driver for v2.6.33.2 if the tablet is serial.

My first concern was trying to edit the Xorg.conf file. If deleted and Puppy rebooted or X restarted, Xorgwizard will always recreate the Xorg.conf file exactly as it was initially installed. The edit suggestions scattered through this 19-page thread will not "take" either. When those edits are put in exactly as given, X will fail and xorgwizard is necessary to get it going again. However, through much trial and error and by editing one line at a time and testing I have created a decent Xorg.conf that will persist through restarts and reboots. It contains the server section and the input device sections.

The Xorg portion of linuxwacom-0.8.8-11-k2.6.32.28-w5.tar.gz found in this thread seems to be what is needed for Puppy 5.2.8. Wacdump , xsetwacom and xidump all yield their expected results. The Xorg driver may be good to go. The kernel driver section is for a different kernel and does not work. The result is an "invalid module" error.

User Tokenrove from the Ubuntu forum http://ubuntuforums.org/showthread.php?t=1780154 has created a patched version of the Linux Wacom Project's kernel driver. It needs to be compiled against the 2.6.33.2 kernel and then have the patches applied. My attempts at compiling have been disappointing. I have worked with FORTRAN but never C. I'm so far behind the curve that it looks straight from here!

The combination of those two software items just mentioned plus the modified edits in the xorg.conf will probably yield a satisfactory solution to getting the Wacom Digitizer 2 and the Wacom Artz 2 serial tablets working in Puppy Linux 5.2.8.

Hi,
here is xf86-input-wacom-0.17.0 for k3.2.29 driver
enjoy

Charlie6,

Thanks for the reply. Your suggestions apply to the xorg portion which as I posted is already working as expected. The current need is for a kernel module compiled against the 2.6.33.2 kernel and patched appropriately for the protocol 4 serial wacom tablets.

I would be overjoyed if you would like to attempt the compile just to see if you get the same errors that I get here. That would help show what I may be doing wrong. Can you compile against the 2.6.33.2 kernel?

Hotdog,
are you serial tablets in the following list (picked up from linuxwacom «old» or «legacy» website)

charlie6 · Joined: 30 Jun 2008 Posts: 812 Location: South of Belgium

Hi hotdog,
all these written on lupu-528 + USB wacom volito tablet + 0.15.0 wacom.ko + xf-86-input-wacom_k2.6.33.2

hmm..given without warranty

attached pieces: just drop the .gz extension as also the «-0.15.0» version to read them as text files, and to get the .ko drivers.

I compiled the input-wacom-0.15.0 driver just to see ... what could happen as the linuxwacom-project website tells it is an USB-driver (...and i have here only USB-wacom tabets...i am not interested at all, am i Wink

? ).
IMHO, the drivers present with the lupu-5.2.8.iso might work with your serial tablets, if these have been included in the development of the driver.
So go to step 2. hereunder; for using the latest input-wacom-0.15.0 driver go to step 1. hereunder;
1. Compile went good and i found 2 drivers:
- wacom.ko driver compiled for USB use (42K against 32K for the one in lupu528's iso)
and something that mightinterest you ...
- wacom_w8001.ko driver compiled for SERIAL use (8492B against 6469B for the one in lupu528's iso)
Read «how to» in the attached piece «wacomdotko_readme.txt»
which are instructions for use of the driver, which come at the end of the make step.
2. I believe you should do in a console

Charlie6,

And you said that you did not know anything about compiling kernel modules! I'm impressed, not only with your success but your helpfulness, too. I appreciate being able to compare our Xorg configurations. That may be a big help when the kernel module is working. Unfortunately, the wacom_w8001-0.15.0.ko is for a touchscreen PC-type device and not related to the serial-connected Digitizer 2 (mine) or the Artz 2 (also called the UD series or protocol 4 series). However, I still tested it. The good news is that what you compiled was accepted without error on my machine.

Would you be so kind as to attempt compiling the attached file. Even if it did not compile, I would like to compare the errors it produces when you attempt compiling it against the 2.6.33.2 kernel. It has a short makefile included.

Thanks for your help!

Hi hotdog,
I believe one should here ask for help to C programmers.

...in attachment the comments of a compilation attempt using the wacom_serial.c and makefile from your last post.; attempt performed on the same system as the driver compile above.

I am far from being a C programmer. I even had to google around to find out how to compile a C file ... as i ignore all about C programming language and the way compiling it...

The attached files might give you a rough idea about the kinds of errors encountered.

So, at this point, i am sorry not being in the possibility to help you more.

Chers, Charlie

Load devx sfs and kernel source sfs. Extract the content of tarball for example to the /usr/src/linux/drivers/input/touchscreen ie Makefile over existing one and wacom_serial.c

Cd to that directory and run in console:
make -C /lib/modules/`uname -r`/build M=`pwd` wacom_serial.ko

If the compile is succesfull, copy the created kernel module to appropriate directory in /lib/modules/....
Run depmod and load the module.
Might even work.

This kernel driver module was test compiled in dpup exprimo 3.4.2 kernel version

Hi pemasu!
thanks for helpîng !
i believe i have had a wrong understanding of how to understand 'uname -r' and 'pwd', as also having misinterpreted spaces. So have made a few cut-and-try replacing
'uname -r' by 2.6.33.2
and
'pwd' by
/usr/src/linux/drivers/input/touchscreen

Have also placed the Makefile and the wacom_serial.c in
/usr/src/linux/drivers/input/touchscreen.

here is what i get (an error...) doing:

Charlie6. You dont have to even replace them. They are picked up, but I suppose it wont hurt to give exact kernel name and location of source directory.

But....It looks like the source is not compatible with 2.6.33.2 kernel. It probably is just too old.

I meant the driver source, lol. Not the kernel source. The Lucid Puppy kernel source is couple of years old, it sounds right. There has not been reason to update the source because there has not been any changes in the kernel. It has been the same all the time. But the problem is not the kernel source, it is incompatible driver source for that kernel version.

kernel_src_L4-2.6.33.2-patched.sfs is the one I seem to have in my own hdd repo.

EDIT. You can always make the safe side and prepare the kernel sources for module compiling.
in /usr/src/linux....type in console: make clean and.... make prepare

Charlie6,

Thanks for doing the compile. The information that you returned is exactly what I am interested in. This bit of code came from one of the developers of the Linux Wacom Project. Once compiled it has to have patches applied. But it must be successfully compiled first. Your efforts yielded the same error that happened here. Now I know that it is not an anomaly in my setup and I can work on fixing the code.

Pemasu,

Thanks for joining in. I tested your compiled driver. Since I'm using Puppy 5.2.8 with the 2.6.33.2 kernel the versionmagic string mismatches and I get the "invalid module" error. However, your successful compile on the 3.4.2 kernel may mean that the driver code is intended for a newer kernel than mine. It may also be expecting a newer compiler. What version of gcc are you running? I have gcc 4.4.3 here.
