tslib Issue

tslib Issue

[openembedded]

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!

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...

Re: tslib Issue

[Neil MacMunn]

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?

are you using X11 with evdev driver then tslib will not be used at all. You
have to use xinput-calibrator.

Re: [Openembedded-users] tslib Issue

Hi,

 

Perhaps a dumb question, but - should the recipe for x11-gpe-image be updated then? I ask because it's what set up tslib (rather than xinput-calibrator), and then evdev.

 

Thanks!
