I've applied the fix from my libts sources so you can calibrate to the screen edge, new tcz is on dropbox. I'm surprised the ts_calibrate issue has not been fixed in the master libts repo. I don't know why you're getting the weird release coordinates and without the same screen it's hard to even help. Perhaps one of the 'other tslib modules' (https://github.com/kergoth/tslib/blob/master/README.md) might help. Using the default ts.conf in the dropbox tcz this is the results from the official rpi 7" screen. $ ts_print 1526216837.887737: 293 211 255 1526216838.167722: 293 211 0 1526216839.527724: 294 209 255 1526216839.777719: 294 209 0 $ ts_print_raw 1526217072.217732: 375 257 255 1526217072.697721: 0 0 0 1526217073.257725: 366 258 255 1526217073.697731: 0 0 0 1526217074.137734: 362 258 255 1526217074.537721: 0 0 0 Ralphy *1*-Touch, *5*-Classics, *3*-Booms, *1*-UE Radio 'Squeezebox client builds' (https://sourceforge.net/projects/lmsclients/files/) 'donations' (https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=LL5P6365KQEXN&lc=CA&item_name=Squeezebox%20client%20builds¤cy_code=USD&bn=PP%2dDonationsBF%3abtn_donate_SM%2egif%3aNonHosted) always appreciated. ------------------------------------------------------------------------ ralphy's Profile: http://forums.slimdevices.com/member.php?userid=3484 View this thread: http://forums.slimdevices.com/showthread.php?t=108852 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
