Public bug reported: if you follow the directions on https://wiki.ubuntu.com/ARM/RaspberryPi
sudo apt-get install xubuntu-desktop about 20% thru the installation it will ask which window manager you want (using dpkg-reconfigure). if you select lightdm, you will only get a blank greeter screen after you reboot. using sudo dpkg-reconfigure gdm3 resets this to gdm3 and after a reboot, everything is fine. this was done on a clean armhf eoan install on a 4gb raspberry pi 4B. I have done the install several times. This bug is repeatable. ** Affects: software-properties (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849886 Title: lightdm does not work on eoan on raspberry pi 4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1849886/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
