我正在尝试在 Raspberry Pi 4 上使用 Ubuntu Server 22.04。我已经安装了 ubuntu-desktop-minimal 软件包并重新启动，但 Pi 上没有登录屏幕，只有一个闪烁的破折号。
我也尝试过 ubuntu-desktop-raspi 和 ubuntu-desktop 包，但没有成功。
我也尝试过编辑 /etc/gdm3/custom.conf 并取消注释WaylandEnable=false以尝试不使用 Wayland，但结果是一样的。
在启动期间，屏幕似乎工作正常，我的显示器上出现了启动日志等。
GDM 似乎正在运行，但在日志中显示以下内容：

我已经在 GDM 中启用了调试并再次运行它，日志可以在这里找到：https://pastebin.com/ze8PWHEd

不确定下一步该尝试什么
答案1
按照这个答案我添加了dtoverlay=vc4-fkms-v3d它/boot/firmware/config.txt并且现在可以工作了。
我会接受任何可以解释这意味着什么的答案，如果有更好的选择，这个设置有效，但我不知道它的作用是什么。
