Re: [Bug 626769] Re: Work around possible touch hardware issues in Lenovo T410s
bzr branch lp:~rafi-seas/+junk/ntrig_calib Calibration should take less than 1 minute to run. If it doesn't improve the first time, try once or twice more. If that still sucks, the windows ntrig control panel has another calibration routine that actually gives a bit of feedback (I don't really have a large enough sample space to decode the output reliably). And if that says all is good and it still sucks, look for firmware updates and complain to the manufacturers ;) As Henrik says, some traces might be helpful.

Re: [Bug 626769] Re: Work around possible touch hardware issues in Lenovo T410s
I watched the video. I understand more now. it looks a small mapping problem in mtview rather than something in the ntrig driver/fw ! The mtview supposes the window in fullscreen and doesn't detect if the window is placed somewhere in the screen. For unity, you have the bar on the Left which takes ~100px. The topbar is also counted. it's a small problem of mapping raw hw input to the output. Duncan, try running the Gnome DE and you'll probably see that you'll no more have the problem of unity pixels (misplaced pixels in right). i On Wed, Sep 8, 2010 at 9:54 PM, Duncan McGreggor dun...@ubuntu.com wrote: Here's the movie I had mentioned. ** Attachment added: movie of mtview showing issues with Lenovo T410s https://bugs.edge.launchpad.net/utouch-grail/+bug/626769/+attachment/1558055/+files/20100908_001.mp4 -- Work around possible touch hardware issues in Lenovo T410s https://bugs.launchpad.net/bugs/626769 You received this bug notification because you are a member of uTouch Team, which is subscribed to utouch-grail. -- Work around possible touch hardware issues in Lenovo T410s https://bugs.launchpad.net/bugs/626769 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

is this problem only found in the T410s ? I tested on my hp tx2 and I haven't figured any problem or ghost contacts.

Re: [Bug 626769] Re: Work around possible touch hardware issues in Lenovo T410s
I'll test several times to see if any problem occurs. But I haven't noticed this problem before (I still have no problems with the hp tx2).
