problem with  touchscreen driver

Posted on 2007-08-01

I am installing Penmount USB touchscreen drivers on Linux (Fedora).
I have xorg.conf being setup properly and I make mouse invisible using unclutter and the whole thing seems to work... sometimes! Most of the time though when I touch the screen I see erratic mouse movements. But sometimes (and worst:  I cannot figure out the pattern) it works.
Any ideas how to approach this problem are very welcome.

    What shows your /var/log/Xorg.0.log ?

    I solved the problem. It was the old driver.
    I can give 50 points to Liganic for trying to help. I think it is fair?

    sure. Glad you could solve it, can you describe what the exact problem was, in case somebody has the same error!?

    Accepted Solution

    The very important thing is to make sure the device line in the /etc/X11/Xorg.conf:
    Option      "Device"       "/dev/input/eventX"
    is corresponding to the actual pointing device.
    In simple words, X ln eventX should be the same as in /proc/bus/input/devices.
    I don't know if Linux can automatically adjust it.

    Then, there is obviously the right driver. In my case,

    And then, using the unclutter utility to make cursor disappear (although I don't know if this makes any difference)

    Now,  how do I split the points?
