Hmm, I thought I was using xserver-kdrive!

(Have PREFERRED_PROVIDER_xserver = "xserver-kdrive" in the machine conf 
file)

Looking closer at the image (x11-at91sam9-image), it contains
XSERVER = "xserver-xorg \
            xf86-input-evdev \
            xf86-input-tslib \
            xf86-video-fbdev "
so the xserver-kdrive is overridden.

This was copied from "xorg-image.bb" which I guess then have the same 
problem
using full x-server and tslib.
"qt4-x11-base-image.bb" has this combination as well.

"xserver-common_1.33.bb" is built and contains:
+++++++++++++++++++++++++
RDEPENDS_${PN}_append_angstrom = " tslib-calibrate "
RDEPENDS_${PN}_append_shr = " xinput-calibrator "
-----------------------------------------------------
and I am building "angstrom" I do not get "xinput-calibrator"

I added xinput-calibrate to the x11-at91sam9-image, but after the build,
Removed "xf86-input-tslib", but the dependence on "tslib-calibrate"
remains in "xserver-common_1.33.bb"
Maybe this needs to change as well.

I get the  same startup calibration program ("run-calibrate.sh"  calling 
ts_calibrate).
with the same poor result.

There are no scripts calling "xinput-calibrator".
Shouldn't that happen at startup?

Can call it manually, and then suddenly I am much better off.
Still  it not perfect though.

Any clue to get xinput-calibrate to run at first boot?
