笔者发现 ubuntu 系统登入页面时,自动会显示温度信息:

笔者参考 树莓派连接显示器不亮屏的解决方案,最后屏幕得以在 7 寸(1024*600) 屏幕显示成功。
方法是需要在烧录的镜像系统中的 config.txt
补充以下内容:
hdmi_force_hotplug=1config_hdmi_boost=4hdmi_group=2hdmi_mode=9hdmi_drive=2hdmi_ignore_edid=0xa5000080disable_overscan=1
步骤一: boot 盘新建一个 ssh 空文件。
步骤二: boot 盘新建一个 wpa_supplicant.conf,里面代码为
country=GBctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdevupdate_config=1network={ssid=""psk=""priority=99}
ssid 写热点名称,psk 写热点密码。
