056a:00d6 [Asus V-P5G45] Bamboo Pen and Touch - Buttons not working and Touch Unusable

Bug #1181166 reported by Phill on 2013-05-17

Bug Description

Clean installation of Ubuntu 13.04 with latest updates. I'm sure that this all worked perfectly under 12.04 without any tweaks. I'm not sure which package this is in as the code is spread between kernel modules and an X11 driver.

Using Wacom Bamboo Pen and Touch, the buttons don't work and the touch motion is so excessive that it goes from edge-to-edge over about a third of the touch area. Note that touch motion is independent of settings for the pen, it is always relative in recent releases.

Pointer movement is unpredictable with small movements producing both large 10+pixel step changes and small 5-pixel step changes for no apparent reason. Buttons work on the log-in page only.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.10 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Noticed that the buttons work on the log-in page, but not once you're logged in. I've updated the description to include this and to clarify the pointer movement issue.

I done a little more testing. If you "cat /dev/input/wacom-touch" clicking the buttons does dump some output to the console, so it's getting that far. Hope that helps. Let me know if I can do anything productive to help fix this.

I just updated the BIOS and it had no effect, the behaviour is the same.

Phill (phill.l) wrote :

Just to help confirm/refute the BIOS/motherboard hypothesis I tried the device on my laptop also running 13.04. Exactly same faults (unusable precision using touch and buttons not working, the pen works fine). If you like I could boot 12.04 to re-confirm it's a regression and try 12.10 to help narrow it down?

Here's the command output from my desktop that you asked for:

I don't understand what "Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful" means.

Thanks for looking into it. Sorry about multiple posts, kept forgetting things.

Phill, thank you for updating the BIOS, and checking against another hardware platform. BIOS updates are requested, both to rule out fault of outdated and buggy BIOS, and collateral damage avoidance.

>"If you like I could boot 12.04 to re-confirm it's a regression and try 12.10 to help narrow it down?"

That would be very helpful. Could you please re-test Precise and Quantal and advise on the results via http://releases.ubuntu.com/ ?

>"I don't understand what "Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful" means."

This was put into my request statement because too many folks who didn't read carefully/understand would just post the information on the old BIOS, and I would have to send another follow e-mail advising on this.

>"Thanks for looking into it. Sorry about multiple posts, kept forgetting things."

Thank you for your patience and understanding.

I can confirm that the device works perfectly on 12.10 (live usb).

Sorry for the delay, I thought I'd updated this. Just re-ran the test to be sure too.

Phill, thank you for testing Quantal. Could you please test Trusty, and advise if this is still reproducible via http://cdimage.ubuntu.com/daily-live/current/ ?

Phill (phill.l) wrote :

Just tried Trusty.

The pen seemed to work as it does in other version (including the rocker button on the pen - thought I'd clarify as I don't think I have before, it's only the buttons on the pad that don't work).

Touch movement appears to have improved, but it's still not as good as the precision that I used to get or what you'd expect on a touch pad - it's not jumping 10-20 pixels like in previous versions but you don't get that pixel precision you'd normally get by rolling your finger slightly.

The on-pad buttons still don't work, however, I noticed that they did work on the start-up screen of the live USB when choosing between Try Ubuntu and Install Ubuntu (or whatever those options are), but when you click Try Ubuntu and get the normal desktop the buttons stop working.

This bug is fixed in the 3.17 upstream kernel.

I installed the latest upstream kernel to check on another issue, but gave this a try at the same time and it works fine.

Wasn't sure if I should change the tags as it already had an upstream related tag on there.

I used http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17-rc1-utopic/

Phill, the next step is to fully reverse commit bisect the kernel in order to identify the fix commit. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

I hope I've done this right as it's taken ages.
Of the re-built kernels I narrowed it down to 3.16.3 which didn't work and 3.17-rc1 which worked.

Here's the git bisect log, good and bad being reversed as in the instructions. The final commit has working buttons, however, on many of the builds between 3.16 and 3.17-rc1 the desktop failed to show, but it was still possible to test the buttons working. , On some the tablet didn't work at all, but I just marked these as 'good' (meaning bad) and continued. This is the case for the winning commit at the end.
