--- Comment #9 from Sollace <solla...@gmail.com> --- As a workaround (thanks to the people over at endeavoros who documented it over here https://forum.endeavouros.com/t/reset-pen-tablet-calibration/64464/6 ): I was able to reset it manually by editing ~/.config/kcminputrc to remove "CalibrationMatrix" line. #CalibrationMatrix=-5.252659320831299e-07,-0.5096684098243713,1.5764576059493218e-12,0,-1.6921096630539978e-06,0.6959778070449829,2.694799068679414e-14,0,0,0,1,0,0,0,0,1 After a reboot the tablet is working again, though I don't intend on using the calibration function any time soon. Overall experience is it doesn't work very well and I'm able to get better results by using OpenTabletDriver and adjusting the X/Y/Width/Height values in there. -- You are receiving this mail because: You are watching all bug changes.
