    Default One last thing !

    Hi,

    If you don't know who I am ( which is probably everyone ) I am the network manager
    for a UK school. A few years ago we went openSUSE for all our student machines
    which is around 400 pc's. At the time the school baulked at changing the teacher
    machines so they stayed at Windows 7. Now with the upcoming demise of that OS I
    have one chance to pitch GNU/Linux everywhere and finally get rid of MS. There are
    about 150 teacher machines of which about 80 are in classrooms. This is where my
    problem lies. They use SmartBoards. Smarttech gave up on their Linux offering at
    version 11 which was only released for Ubuntu and that was 14.04. So to end a long
    and possibly boring ramble I need something like SmartBoard software. It doesn't
    have to be as functional , just to be able to write on the board and over presentations
    would be fine. I know LO Impress works fine but for 'political' reasons I can't sell that
    as a solution. Any ideas ?

    Perhaps OpenBoard is a suitable option here...

    Do you mean the “SMART Learning Suite”?

    I assume you mean those whiteboards which work with light pens instead of dry-erase markers.

    Been awhile since I looked into this, but at the time these boards where often proprietary, so you needed to start with the manufacturer and model, then look up the technical specs, and from that you can do an effective search for alternative software.

    As always,
    You can look into whether the software runs in Wine.
    Or, deploy Win7 in a virtual machine to make it difficult although not impossible to hack over the network.

    I have been playing with OpenBoard and the experimental package seems to run on
    Tumbleweed OK with a bit of persuading. There are two things however that I am
    currently stuck on. If someone has the answer it will save me a whole lot of Googling

    1. When you use either Impress or Office 364 and send the presentation to the
    whiteboard it goes over the top of OpenBoard. Since OpenBoard doesn't seem
    to use Plasma I don't know how to make sure OpenBoard is always visible/on top

    2. As anyone who uses SmartBoards knows once they get a bit old the calibration
    is terrible. TW saw the Smartboard immediately as a mouse the calibration is about
    1cm out. Can I tell TW to 'recalibrate that mouse input' so to speak.

    Those things being said I am fairly optimistic that I can at least put on a good demo shortly

    Thanks

    The OpenBoard page link I shared back in post #4 has links to the OpenBoard forum and documentation that might be helpful here.

    Yes, calibrating the 'mouse' input device can be done, and essentially involves creating a calibration or transformation matrix to calibrate the input device concerned...
    https://wiki.archlinux.org/index.php...put_calibrator
    This can be added as a udev rule, or via a custom config file in /etc/X11/xorg.conf.d/ directory.

    Although a script is provided that helps with generating the required configuration, the author mentions that it won't work for a device handled by libinput, however the manual steps are outlined here...
    https://wiki.archlinux.org/index.php...put_calibrator

    Don't feel daunted by it, as it can be scripted to help with the task once the steps are understood. I may be able to help you further with this if needed.

    The available device properties (attributes) can be checked using
    Code:
    sudo libinput list-devices
    There should be a "libinput Calibration Matrix" property or similar. That is what is used to calibrate the mouse.

    Hope that helps as a starter.

    Having never used OpenBoard I'm not quite sure what you mean here, but AFAIU it is using the QT 5 framework since version 1.3, so I would hope it operates nicely with KDE. It can apparently be started in 'Board' or 'Desktop' mode as desired. The OpenBoard forum may be a good place to get further community support.
