I don't see any usage of calibration options MaxX MinX MaxY MinY in
http://cgit.freedesktop.org/xorg/driver/xf86-input-elographics/tree/src/xf86Elo.c
after this commit
http://cgit.freedesktop.org/xorg/driver/xf86-input-elographics/commit/src/xf86Elo.c?id=447f547fbb7d11ec56ea578292908192175b3828
Also my elographics(GeneralTouch) device are shown as [floating slave] in
xinput list. When I xinput reattach it, it acts as not calibrated.
I think we should add something like
int width = priv->max_x - priv->min_x;
int height = priv->max_y - priv->min_y;
cur_x = (priv->screen_width * (cur_x - priv->min_x)) / width;
cur_y = (priv->screen_height -
(priv->screen_height * (cur_y - priv->min_y)) / height);
in xf86EloReadInput(InputInfoPtr pInfo)
or use xf86ScaleAxis()
or use correct screen and max/min values in this stuff
/* I will map coordinates myself */
InitValuatorAxisStruct(dev, 0,
axis_labels[0],
-1, -1,
9500,
0 /* min_res */,
9500 /* max_res */,
Absolute);
InitValuatorAxisStruct(dev, 1,
axis_labels[1],
-1, -1,
10500,
0 /* min_res */,
10500 /* max_res */,
Absolute);
I'am going to try first way soon.
