나도 찾았어이것게시물에서 동일한 문제를 설명하고(Gen1 대신 Hyper-V Gen2에서) xf86-video-fbdevDebian용 해당 패키지를 다시 설치 하도록 제안했습니다 lightdm.

sudo apt-get install --reinstall xserver-xorg-video-fbdev
sudo apt-get install --reinstall lightdm

내가 정확하게 기억한다면 그것은 사용자에게 자격 증명을 묻는 GUI인 환영 프로그램이라고 불립니다. 그래서 lightdm 구성을 확인했습니다.

$ sudo lightdm --show-config
[sudo] password for user: 
   [Seat:*]
A  greeter-session=lightdm-greeter
A  greeter-hide-users=true
A  session-wrapper=/etc/X11/Xsession

   [LightDM]
B  logind-check-graphical=false

Sources:
A  /usr/share/lightdm/lightdm.conf.d/01_debian.conf
B  /etc/lightdm/lightdm.conf

lightdm-greeter맞는 인사말 인가요 ? 내가 Greetingr를 검색하면 lightdm-gtk-greeter, lightdm-deepin-greeter, 등 lightdm-pantheon-greeter을 찾을 수 있지만 lightdm-webkit2-greeter아무것도 없기 때문에 이것을 묻습니다 lightdm-greeter.
