I was impacted by this on 2 VM's I have (while using lightdm-gtk-greeter). Both of them have been upgraded from Xubuntu 20.04 to Xubuntu 20.10. After the update, the effects were as follows: 1) one of the VMs (VMWare) lacked the icons and wallpaper on the greeter page, but functionally, everything was working, I was able to login. 2) one of the VM's (Virtualbox) entered in a loop in which tried to start the lightdm-gtk-greeter 5 times, without success, resulting in a black screen. I checked the logs in /var/log/ligntdm
I was running version 2.0.6-0ubuntu1 on BOTH VM's. I was able to bypss this by uninstalling lightdm-gtk-greeter and installing unity-greeter. I enabled the pre-released updates and installed the lightdm-gtk-greeter version 2.0.6-0ubuntu2 Note the 2 at the end. After installing this newer version of the package, the problem was instantly solved, and I was able to switch back to lightdm-gtk-greeter without any issue. Icons were visible again, wallpaper was visible again, and I did not have a black screen anymore. I confirm the fix is working, at least for the lightdm-gtk-greeter package. Thanks for this fix, when the new version will be present in the official channels, I will upgrade to 20.10 all my fleet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890394 Title: Lightdm-gtk-greeter coredump during boot with recent systemd versions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm-gtk-greeter/+bug/1890394/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
