我开始在我的 Banana Pi 上使用 Armbian（主线内核）来使用 Nextcloud 和 Apache，现在我想通过将触摸屏连接到它以实现基本的 SmartHome 使用来提高它的可用性（我将编写一个小型 Qt 应用程序来控制灯和暖气等）。
所以我买了一个5" HDMI 触摸屏并安装了网站上给出的驱动程序。
之后，我尝试安装 XFCE4正如所解释的并尝试启动它，导致以下错误日志：

我寻找 lightdm 是否有问题。systemctl status lightdm看起来如下：

正如 XFCE 所说，没有找到屏幕（顺便说一句，LCD 已连接并工作，但始终只显示 Armbian 徽标和光标），我开始猜测可能存在驱动程序问题，或者是否有我在安装期间错过的东西步骤？
我不想使用带有 GUI 的旧内核版本重新安装 Armbian，因为我花了数百万的精力才让 Nextcloud 运行。
编辑：也许lsmod输出也会对那里的人有所帮助。

我已经尝试安装软件包linux-u-boot-bananapi_5.38_armhf，linux-headers-sun7i_5.38_armhf并且linux-image-sun7i_5.38_armhf
提前致谢。

Xorg 日志显示服务器找不到该fbturbo模块。您是否fbturbo按照以下方式安装了http://wiki.lemaker.org/BananaPro/Pi:GPU？
