Bug Description

I have a Lenovo x220i tablet with the same wacom lsusb device id running Natty similar to another bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/746652. I've opened a new bug under request in case it is a different issue.

Basic pen functionality works, but single touch finger touch does not.

When touching with the finger, the pointer follows the finger, but upon release the pointer goes to the top left.

The effect is:

Touching icons in the launcher:
* does not launch, instead "scrolls" the launcher when releasing
Dragging a window
* ends up always dragging the window to the top left
Using gimp to draw a circle
* canvas correctly paints until releasing the finger, at which
point a line is drawn to the top left

I am using Natty, updated, and using the latest proposed kernel
* Linux thinktablet 2.6.38-9-generic #43-Ubuntu SMP Thu Apr 28 15:23:06 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

I will attach an image I produced in The Gimp, one with the pen drawing shapes (bottom row) and another with my finger drawing the same shapes (top row). As you can see, the mouse even "drags" toward the the top left corned (0,0) of the screen before recognizing the finger has been removed.

Using Multi-touch lets the coursor jump between the two positions, while clicking ist active.
This may be a problem of x11, to handle multiple cursors the same time.

Bug is partly solved in Kernel 2.6.39.1. The curser wont jump to the upper left corner, but it doesn't fit the finger movement anymore.

Bryce Harrington (bryce) wrote on 2011-06-22:

@David, does 2.6.39.1 fix the jumping to 0,0 for you as well?

@Christian, the finger movement issue should be filed as a separate bug.

Could be kernel bugs in both cases.

@Bryce, I no longer have my x220i, but I'll ask someone that might have access to one.

We can re-open the bug if it is not fixed.

Thanks.

Hi, I just tested the x220t with the 2.6.39-3 kernel.
The result isn't what I expected. The curser doesn't jump to the 0,0 position anymore. But the mouse is not moving to the absolute finger position. You can move it by sliding with your finger over the screen (like the touchpad).
Clicking works also (but on the positon where the mouse is and not at the position of the finger).

In short: The screen works like a huge touchpad.

I just installed Oneiric with todays latest updates on my x220 tablet, as well as the utouch related packages. The touchscreen worked fine with the pen device, but acted like a large touchpad when using my finger. I followed the steps in entry #29 in this ubuntu forum thread:
http://www.ubuntuforums.org/showthread.php?t=1785015&page=3
and now it works. The summary of steps is:
1) downloaded xf86-input-wacom-0.11.1.tar.bz2 (the latest)
2) run `./configure --prefix=/usr` to make sure things are installed in the right places
3) modify "conf/50-wacom.conf" according to the forum entry to include "ISD-V4" in the "MatchProduct" line
4) ran a make/make install, and rebooted.

Before trying this, I simply tried adding "ISD-V4" to 50-wacom.conf in /usr/share/X11/xorg.conf.d and copying over to /etc/X11/xorg.conf.d, and that didn't do anything. I'm thinking, but can't confirm, that we may just need to update our version to match upstream.

On Natty I had the same issue (cursor jumps to corner upon finger-tip, worked with pen) and I applied the steps above (wacom), but NOW I have the "huge-touchpad feeling" actually described in the bug. Has this bug been resolved for you?

@SL: No, with the workaround, I can touch icons to start and move windows as well. I'm also able to do two-finger zoom with Firefox..so I **think* it's working, but still need to do a bit of testing. I'm also using Oneiric, so different version of the kernel and other related packages I'm sure.

https://launchpad.net/~bryce/+archive/lp787781/ has the fix, but someone with the hardware needs to test it to verify. Once that's done I can try getting it into Ubuntu.

David, ok thanks.

I'm going to go ahead and upload it since I'm 99% sure this fixes it, but I really wish someone would test it to be sure.
