另外，亚克力底板在 emmc 的位置是不是可以切割留出口，方便拆卸emmc
每次都要螺丝扭一遍，很那个

比亚克力那个好多了，不要太贵，我买

你是用 0303的版本还是 0306的版本？我猜测是驱动没有安装

试试

sudo apt-get udpate -y
sudo apt-get dist-upgrade -y

sudo reboot

@jack_admin 请问这个怎样绑定？

@jack_admin

镜像包： 20230306-ubuntu-22.04-preinstalled-desktop-arm64-coolpi.zip

安装完成后，系统有预设用户coolpi,能够正常工作。
然而创建一个新的Administrator用户 edwardzhou
用edwardzhou 这个用户登录桌面后，无法运行 firefox 等程序，点击 Log Out 想登出切换到其他用户，一点击 Log Out, 系统桌面就挂死。

在 TTL 终端上可以看到输出的日志
