      系统终端输入dmesg > kernel.log

      把kernel.log发上来看下。

          vim /boot/firmware/config.txt 一样修改dtb文件名试下。你的机器是什么时间收到的,早期的loader不识别extlinux.conf

          另外查看下 ls -l /sys/class/drm/

                @tonyone0902 如果有环境,建议更新到0315 版本loader。

                  我也试了微雪的这个5寸屏
                  不支持双指 打开一张本地的图片 不能用双指进行缩放 只能用鼠标滚轮缩放
                  但是这个屏接树莓派4b是能用双指缩放的
                  这个需要改哪里吗?

                        可以试下修改内核源码

                        drivers/input/touchscreen/tinker_ft5406.h
                        @@ -13,7 +13,7 @@
                         #define FT_REG_FW_SUB_MIN_VER  0xB3
                         
                         #define VALID_TD_STATUS_VAL            10
                        -#define MAX_TOUCH_POINTS               1
                        +#define MAX_TOUCH_POINTS               5
                        

                        重新编译内核,替换Image
