GDM无法使用UbuntuServer22.04启动RaspberryPi 4
GDM无法使用UbuntuServer22.04启动RaspberryPi 4
提问于 2022-06-20 16:10:24
我试着在Raspberry Pi 4上使用UbuntuServer22.04，我已经安装了Ubuntu桌面程序包--最小化和重新启动，但是我在Pi上没有登录屏幕，只是一个闪烁的破折号。
我也尝试过ubuntu桌面-raspi和ubuntu桌面包，但没有效果。
我还尝试过编辑/etc/gdm3 3/custom.conf和取消注释WaylandEnable=false，尝试不使用Wayland，但是结果是一样的。
在启动期间，屏幕看起来正常，我看到启动日志出现在我的显示器等。
GDM似乎正在运行，但在日志中显示了这一点：

根据这个答案，我将dtoverlay=vc4-fkms-v3d添加到/boot/firmware/config.txt中，现在可以工作了。
我会接受任何能解释这意味着什么的答案，如果有更好的选择，这个设置可以工作，但我不知道它能做什么。
