Attempting to calibrate a touchscreen, only the first of xmin, xmax, ymin, ymax is accepted. No matter what order, only the first has any effect.dtoverlay=ads7846,penirq=25,speed=10000,penirq_pull=2,xohms=150,xmin=200,xmax=3800,ymin=200,ymax=3800System:Raspberry PiRaspbian JessieMakibes 5 resistive touch screen SPI interface XPT2046 chipset.I also tried using a calibration file, /etc/X11/xorg.conf.d/99-calibration.conf, but that had no effect, although it did show in /var/log/Xorg.0.log.Any ideas what to look for?
