My first day of rage at X

Yesterday, I wrote about X adding an undesired mouse. Today I looked at it, and...

xorg-x11-server-1.1.1-54.fc7/hw/xfree86/common/xf86Config.c:


    /*
     * hack: always synthesize a 'mouse' section configured to send core
     * events, unless a 'void' section is found, in which case the user
     * probably wants to run footless.
     */
    int _found = 0;
    IDevPtr i;
    for (i = servlayoutp->inputs; i->driver; i++) {
        if (!strcmp(i->driver, "void") || !strcmp(i->driver, "mouse")) {
            _found = 1; break;
        }
    }
    if (!_found) {
        xf86Msg(X_INFO, "No default mouse found, adding one\n");

Thus, the solution:

Well, well, well. At least this is open source. With Windows, I'd never know what hit me (or had to buy a hideously expensive book, and sign up for MSDN).

The motion is not jumpy anymore, but still not correct. I feed correct values into xf86PostMotionEvent(), but my ->conversion_proc receives them weirdly scaled (by about 20%, and offset). Dunno what's up with that.

{Fridge update: git can tell the commit, and the author turns out to be none other than ajaxxx. What was he thinking?}
