xinput-calibrator

[Martin Jansa]

Hi,

I've seen your patches for xinput-calibrator. I'm not sure if you're
the author (github is down now ;/), but maybe you could add this
anyways.

For shr I've added small shell script to run calibration only if 
/etc/pointercal.xinput doesn't exist and after calibration store values
there for next reboot.
http://git.openembedded.org/cgit.cgi/openembedded/commit/?id=48dd2427c14edb8349e9f16150ad0f9c037c2ab8

This is then used in Xsession.d script.
Problem is when user wait too long when starting xorg for first time and LCD 
screen is blanked, then first touchscreen tap to unblank it counts as
first point for calibration (way off the right mark).

I've workarrounded it with forcing LCD to stay on while calibrator is
running but still not best solution (ie user can touch ts by accident
even with display on.

Could you add option (ie enabled by command line param, or even by
default) to repeat calibration when user doesn't confirm that he did it
right and touchscreen is working for him?

Something like (while still in xinput-calibrator gui):

Do you want to use/store calibration values?
If yes, press touchscreen for 10s.
If no, press once and calibration will start again.
(maybe some 3rd option to exit calibration without storing)

(buttons would be easier to use, but difficult to press the right one if 
user messed calibration really badly).

Thanks!

pointercal ignored?

[Ulf Samuelsson]

I have built a custom variant of x11-gpe-image for the SAM9M10.


I am running the dev branch (1-2 weeks old)
The pointcal file generated by ts_calibrate in
seems to be reasonable, indicating that
the touchscreen is pressed (50,50) away
from all four corners.

When gpe is started, the Y direction seems to be compressed.
When I start the calculator and press at the top of the screen,
the calculator buttons 5 mm below gets pressed.
When I press at the bottom of the screen, the buttons 5 mm above
gets pressed.

Changing /etc/pointercal manually seems to have no effect

It's like pointercal gets ignored.

When others run the same kernel with minor config changes
using the stable branch ans xserver-kdrive, this phenomena
does not happen.

Any clues?

Best Regards,
Ulf Samuelsson

Which machine in OE covers that board? I have to admit that I did not tried to 
hack mine.

Check do you have kdrive or xorg with evdev or tslib driver.

I am building the SAM9G45EK, but I am using a 2.6.30 kernel
patched with maxim.org.za + www.linux4sam.org .exp3 patches
instead of the 2.6.32 currently in openembedded.

Also updated bootstrap and u-boot, but that won't affect this.

I will check, when I am back home.
Will also send the patches I added.

If you want pointercal to be use, you need to install xf86-input-tslib
