HP Touchsmart tm2 requires newer wacom driver

That happens on HP Touchsmart Tx2 too!

The only way to get it working is that: http://ubuntuforums.org/showthread.php?t=1252492
but, multi-touch is not working!

Thiago,
     Please open a separate bug for this new hardware.

Thanks!

Generally speaking, Ubuntu includes sources directly from upstream with individual fixes only where necessary for bugs that cause severe issues (such as kernel crashes). Exceptions are made from time to time, but this is the preferred flow of sources into Ubuntu for many reasons.

As such, the preferred route for the fix for your issue is to have the changes percolate up from the beta sources of the linux wacom project to the stable sources of the project to the mainline linux kernel. Once it reaches the mainline linux kernel we prefer to have the fixes come through the -stable series that are separately maintained for back versions of the kernel, which is usually what the Ubuntu development distribution is based on. Our Lucid kernels are based directly off of the -stable series, so changes there likely will be incorporated into our kernels automatically.

Unfortunately, that means a bit of waiting for end users of new hardware that does not work out of the box. There are a few options that can ease the situation though:

1. Build the updated modules personally
2. Create a dkms package to build the modules for you each time the kernel is updated (and potentially host the packages in a launchpad personal package archive for others to use)
3. Work to incorporate the newer modules into the Ubuntu linux-backports-modules package
4. Inclusion as an "ubuntu" driver in linux-image

Note that option 3 is fairly heavyweight and would necessitate extra work not only to develop the new modules within linux-backports-modules, but also to ensure all the process requirements are met. Option 4 is probably similar in amount of work.

Both options 3 and 4 would still likely require the source to at least become stable in the linux wacom project, and also be an issue for a large amount of end users to be considered.

As such, I am marking this bug as 'Won't Fix'. If the upstream sources become stable and you believe there are a reasonable amount of affected users to pursue options 3 or 4 you may reopen the bug.

Setting back to Triaged.

Brian,
      When you built from the source, did it create one driver or many? If many, which one did you load? We'd like to compare versus what is available in the kernel.

Thanks!

The only driver I built and loaded was wacom.ko.

I've built a test module of wacom.ko. It's based on the latest lucid kernel sources tip + two git commits from 2.6.33 [1] [2]. Please download and test this module in lucid to see if it works (Note: this is very frankensteined and may be unstable!):

http://people.canonical.com/~cndougla/516777/wacom.ko

[1] http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=ee54500d7b960984df125bdd0cd2105d6150e8f1
[2] http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=ec67bbedcf290ef182a897017f65a2707106c7f8

I forgot to build an i386 version. I've swizzled the locations:

http://people.canonical.com/~cndougla/516777/amd64/wacom.ko
http://people.canonical.com/~cndougla/516777/i386/wacom.ko

When I try to insert the module I receive the following error message:

insmod: error inserting 'wacom.ko': -1 Invalid module format

I checked to see if perhaps there was a new version of linux wacom and there is, 0.8.5-10. However, I downloaded that and compiled the kernel driver myself and was able to load it without any problems.

@Brian Murray:

When you see insmod errors, the best thing to do is to check dmesg. Usually more info is available in the dmesg than is given by insmod. Can you post any relevant information from your dmesg? Relevant info should be near the end.

The problem is that the driver from the linuxwacom website is a stand alone package. It is not integrated into the linux kernel tree. The module I built is taken from upstream commits to the 2.6.33 kernel tree. We can't integrate the linuxwacom package into the Ubuntu kernel. The best we can do is create a dkms package for it or put it into lbm if the test module I built won't work.

wacom: no symbol version for module_layout

When I first built the modules I didn't build the entire kernel, just the drivers/input/tablet directory. This didn't allow for the proper modpost run which fixes things up in the module so it can load properly. I've since rebuilt the modules and reuploaded them. The previous urls now have the corrected modules to test with.

Tried it with an Intuos4L to see if anything would break, and nothing did. Tried suspend/resume too with it attached.

Tested i386 module on my Netbook with a Wacom Bamboo MTE-450 (0x056a:0x0065). xev seems to produce events for all its buttons and the pen area and the jog dial (touchpad) work. Same after suspend/resume with the tablet attached.

The corrected modules loaded properly and worked great on my system. Both the pen and the touchscreen work including after suspend and resume.

I have sent an email to the maintainer of the driver, Ping Cheng <email address hidden>, asking for his support in trying to get this into -stable for .32. We will make a decision as to how these changes can be brought into lucid based on the timeframe and nature of his response.

The patches have been committed to the lucid kernel tree. Please make sure to test the next kernel that comes out to ensure that everything is working properly, both with new hardware and old. We need to be sure it works. If we find any issues, we can still pull out the patch before general release.

Also, I've sent the patches upstream to -stable. I doubt they will be accepted, but it's worth a shot. I've been communicating with the maintainer of the driver, and he is supporting the effort.

This bug was fixed in the package linux - 2.6.32-15.21
