Ok.. so out of the box, touchscreen is "upside down" and miscalibrated
on n900. So I need to run

xinput --set-prop --type=float 8 115 1.10 0.00 -0.05 0.00 1.18 -0.10 0.00 0.00 1.00
xinput --set-prop --type=int 8 249 0 1

(or equivalent with names) so that I can use the touchscreen. (And
that's quite important -- X is somehow unusable without pointing
device).

If xinput is not the right solution, what is the right solution?

Thanks,
Pavel
