Question 3:tslib:selected Device isNot a touchscreen (must support ABS and KEYEventtypes) Workaround:1may be because the driver does not support, replace the standard driver, because some drivers are others on the standard driver modified driver, so it is best to replace the official standard driver;2. Export tslib_tsdevice=/dev/input/Event4 pointing to the input device is not correct, pay attention to modify the correct input device;
