We have a major problem here. xserver-kdrive was removed and the
xcalibrate extension was dropped from big xorg. We therefore have
nothing with the xcalibrate extension in it, it was replaced by xinput
stuff which we don't have.

Two options are trying ts_calibrate on the commandline if you can get a
portrait console (kernels can support console rotation, I helped get
that merged years ago) or find the xinput-*-calibration program from
meta-oe and use that.

Ross: Any thoughts here? This isn't good coming up to release.

Cheers,

Richard
