After a few cycles of:
# rm /etc/pointercal
# shutdown -r now
# stat /etc/pointercal
I found that pointercal is only accessed on the first restart after it
has been modified/created.
The problem seems to be that Xorg is started before ts_calibrate runs
for the first time. I found a fairly simple hack that seems to fix the
problem.
# cp /etc/X11/Xinit.d/89xTs_Calibrate /etc/rc5.d/S89xTs_Calibrate
Though this fails to address the situation where ts_calibrate is run and
pointercal already exists - a manual reboot is still necessary for the
new calibration to take effect. Does anyone know of a better, more
permanent fix?

I am seeing the same thing using the omap3-palmtop-image for Gumstix
Overo. On first boot, /etc/X11/Xinit.d/89xTs_Calibrate doesn't find
/etc/pointercal so it runs ts_calibrate. The calibration doesn't take
effect until I reboot though - restarting gpe-dm doesn't solve the problem.
I think that the library /usr/lib/ts/linear.so looks for /etc/pointercal
and defaults to some preset values if the file doesn't exist. I thought
that restarting gpe-dm would reload linear.so (which fuser suggests it
does) but this doesn't solve the problem. It would appear that I am
missing something...

Hi,
I have successfully build and then run several OE images on my target
hardware (h1940) - and have noticed an interesting oddity (bug?).
If I run the opie-image for example, everything works just great.
However, if I run an X-based image (like, say x11-gpe-image) when the
GUI starts up tslib calibration is run ... but then basically thrown
away, as the driver for the touchscreen is set to evdev by default
(and the touchscreen isn't calibrated / does not work right). If I
manually build and install xf86-input-tslib, and then configure the
input as tslib (not evdev) - once I restart gpe-dm it works as expected!
Is this supposed to be the case, or perhaps something not configured
quite right in the builds?
Thanks!
