    9.04 Map tablet to part of screen

    I have a Wacom tablet that, conveniently, was plug and play with ubuntu 9.04. However, I am using dual monitors, treaded as one big screen and because the tablet is currently mapped to the entire screen it is much more sensitive when I move it left or right than up or down, due to the aspect ratio difference between the tablet and the screens.

    My question is, is it possible to map the tablet to only part of the screen, I.E. half of it?

    Thanks,
    Justin Rajewski

    I am pretty sure that this cannot be done, but I would love to hear what the others say about this!

    I just got a 22" monitor + my old 17" so the table is basically useless. It seems like this should be possible, but I don't know about how it all works so I could be wrong.

    Hi Commander_Bob,

    I think it depends partly on your video card. Do you have Nvidia by chance?

    I think what you're asking is "Map tablet to one Monitor". Is that right?

    I do want to map the tablet to one monitor and I do have a Nvidia card (GTX 285).

    Hi Commander_Bob,

    As long as TwinView is ok I think this will work.

    Because there is a "bug" to setup dual screens you need to run nvidia-settings as root.
    Code:
    gksudo nvidia-settings
    Using TwinView, put the monitors where you want them. In X Server Display Configuration->set position to Absolute if screens are not the same resolution, or use Left Of, Right Of if they are. Enter Apply and then Save to X Configuration File. This should make the settings permanent. If you do it from the Desktop Nvidia X Server Settings the configuration isn't saved (although it should be) because you're not root.

    Be sure the tablet's usb is plugged directly in, not through a hub or something else.

    Then you may have to add some options to your 10-wacom.fdi since you're in Jaunty. They'd be something like:
    Code:
              <merge key="input.x11_options.TwinView" type="string">Horizontal</merge>
              <merge key="input.x11_options.TVResolution" type="string">1440x900,1280x1024</merge>
              <merge key="input.x11_options.ScreenNo" type="string">0</merge>
    Except you'd use your resolution. If I sound a little vague on this it's because I am. But this should get you in the ballpark, hopefully.

    Good luck!

    Yes, the wacom settings, usually in xorg.conf, allow defining the area you want to use.

    The nasrty thing is that by default xorg.conf isn't used any more in latest Ubuntu versions like it was before, so you'll have to write your wacom configuration there from scratch.

    Anyway, you'll find the options here: http://linuxwacom.sourceforge.net/index.php/howto/x11

    Hi Commander_Bob,

    I actually don't know what tablet you have so I'll assume it's usb. The usb subsection is the first one. So I guess add them to the end like:
    Code:
            <append key="wacom.types" type="strlist">pad</append>
              <merge key="input.x11_options.TwinView" type="string">Horizontal</merge>
              <merge key="input.x11_options.TVResolution" type="string">1440x900,1280x1024</merge>
              <merge key="input.x11_options.ScreenNo" type="string">0</merge>
    and before the </match> line. The HOW TO mcduck linked you to has some more stuff in sections 11 and 9.

    Re: 9.04 Map tablet to part of screen

    OK, that kinda worked. The cursor is now confined to the left half of the desktop (not the whole left screen). Ideally I would like on the right screen, the standard aspect one. Any ideas?
