[Bug 1890394] Re: Lightdm-gtk-greeter coredump during boot with recent systemd versions
I don't have access to a machine where Ubuntu Focal is installed. AFAICS, this issue currently breaks Ubuntu Bionic LTS completely for non-technical users running Lxde (e.g. Lubuntu) who regularly apply updates (as recommended) without a simple work-around being available. With non-technical users I'm referring to users who aren't comfortable on the command line. That means they can't just log into the console and enable the proposed updates etc. So I consider this as a pretty serious issue for an LTS release. Releasing it rather earlier than later would probably lead to less people being affected (i.e. those who haven't installed the latest breaking updates yet). -- 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

[Bug 1890394] Re: Lightdm-gtk-greeter coredump during boot with recent systemd versions
I upgraded my laptop from 20.04.1 to 20.10 using do-release-upgrade and found that icons were missing in lightdm-gtk-greeter. Logs suggested that icon files and background wallpaper could not load due to out of memory errors. I performed a clean install of 20.10 and the icons were then working but I was faced with a black screen 50% of the time. Logs also showed out of memory errors loading fonts etc. systemd was constantly trying to restart lightdm and failing causing a flickering screen. I added the proposed channel and installed the lightdm-gtk- greeter_2.0.6-0ubuntu2_amd64.deb package from there. Subsequent reboots of my laptop have all worked as expected without any problems.

[Bug 1890394] Re: Lightdm-gtk-greeter coredump during boot with recent systemd versions
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
