#221 Bamboo pen raise not detected every time


Eevery now and then (I'd say a minute or two of usage) when I use my Bamboo CTH-670 in Ubuntu, it happens that when I raise my pen from a press the "release" isn't recognised. Instead, the pen stays in this continuous drag'n'drop mode while I'm moving it (without me doing any more pressing, just moving) which is very problematic - it rearanges my windows, changes the objects I am working on and it's not that easy to get it back to normal. Usually after I press the pen down a couple more times it does return to a normal state, but this recurrent behaviour is very unfortunate.

Expected behaviour
Whenever the pen is raised, no matter what I was doing or how high or fast I raise it - it must switch into a "non-pressed" mode.

I am using Ubuntu 12.04.1 LTS and the wacom drivers I acquired through the normal instructions (though they weren't in the repo, I think I had to add some PPA).

$ dpkg -s xserver-xorg-input-wacom | grep Version
Version: 1:0.14.0-0ubuntu2

If you require some additional information or some log files, just let me know.

    @favux - you're right, I don't have any wacom-related PPAs. I just checked my /etc/apt/sources.list. I don't know why I remembered that. Maybe I had to do install a PPA back in Ubuntu 11.10.

    Anyway, thanks for the advice. First, though, I will upgrade to 12.10 which just came out and see if that changes anything. If the bug still persists, I will try the PPA you mentioned to get version 0.17 or compiling from source.

    Will keep you posted.

    BTW, I found a similar bug-thread (though tied to Lenovo tablets) on Launchpad:

    OK, I have Ubuntu 12.10 and I got the newer version:

    kermit@Glamdring:~$ dpkg -s xserver-xorg-input-wacom | grep Version
    Version: 1:0.17.0-0ubuntu2

    I am still experiencing this bug, but I have noticed something that might be a clue, though. When I hold the pen at the very top, keeping my fingers away from the surface, the erratic behaviour seems to stop. I suspect that somehow when my fingers hover close above the surface, the tablet thinks I am still keeping pressure (maybe I accidentally brush it once in a while), even though I raise the tip of my pen from the surface.

    What is the proper way to completely remove touch input and only leave the pen?

    I was doing that using my own script, which I now believe might have left "some parts" of the touch input still going through and confusing the driver. The script basically finds the xinput id of the Wacom Bamboo Finger input and calls `xinput -set-prop 12 "Device Enabled" 0` on it (where 12 is the xinput id).
