text: <s>[INST] Problem with touch screen calibration 2711P-T15C22D9P. First step: Terminal Settings, then choose Input Devices>touch screen>Calibration. Second Step: Carefully press and briefly hold stylus on the center of the target. Repeat as the target moves around the screen. The problem is that i don't have a message that calibration is complete. All the time the target moves around the screen. When the calibration is complete, a message appears to indicate the measurement of new calibration settings. Right now we use USB mouse to navigate through the interface. [/INST] It might be a hardware issue or a firmware issue. To be sure, you can try to flash the panel with the desired version of firmware. If problem reproduces after that, there might be several touch cells damaged. If not, the new firmware image has corrected a corrupted dll library.\n </s>
