** Description changed: Description: Ubuntu 20.04.1 LTS Release: 20.04 lightdm-gtk-greeter: Installed: 2.0.8-1ubuntu1 Candidate: 2.0.8-1ubuntu1 Version table: *** 2.0.8-1ubuntu1 100 100 /var/lib/dpkg/status 2.0.6-0ubuntu1 500 500 http://ports.ubuntu.com focal/universe armhf Packages Chromebook armv7 install of focal tarball, followed by manual upgrade and xubuntu-desktop install. Selecting lightdm display manager results in the above behavior. Switching to gdm3 *does* work, however, requiring a full gnome-desktop install seems to defeat the purpose of xubuntu-desktop. The workarounds using Memlock in the service file for lightdm have no affect, and neither does a native arm package rebuild of 2.0.6. The one thing that *does* work (besides switching to gnome) is building the debian 2.0.8 package using ubuntu deb tarball. Otherwise all you get are the log errors shown below. The greeter log shows the following: ** Message: 19:40:54.740: Starting lightdm-gtk-greeter 2.0.6 (Sep 18 2018, 01:17:10) (process:5105): GLib-ERROR **: 19:40:54.851: creating thread 'gmain': Error creating thread: Resource temporarily unavailable ** Message: 19:51:32.569: Starting lightdm-gtk-greeter 2.0.6 (Sep 18 2018, 01:17:10) (process:5597): GLib-ERROR **: 19:51:32.571: creating thread 'gmain': Error creating thread: Resource temporarily unavailable ** Message: 20:07:27.951: Starting lightdm-gtk-greeter 2.0.6 (Sep 18 2018, 01:17:10) (process:6133): GLib-ERROR **: 20:07:27.954: creating thread 'gmain': Error creating thread: Resource temporarily unavailable ** Message: 20:09:14.102: Starting lightdm-gtk-greeter 2.0.6 (Sep 18 2018, 01:17:10) (process:6244): GLib-ERROR **: 20:09:14.105: creating thread 'gmain': Error creating thread: Resource temporarily unavailable ** Message: 20:10:52.081: Starting lightdm-gtk-greeter 2.0.6 (Sep 18 2018, 01:17 + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu27.9 + Architecture: armhf + CasperMD5CheckResult: skip + CurrentDesktop: XFCE + DistroRelease: Ubuntu 20.04 + Package: lightdm-gtk-greeter 2.0.8-1ubuntu1 [origin: unknown] + PackageArchitecture: armhf + Tags: third-party-packages focal + Uname: Linux 5.8.12 armv7l + UnreportableReason: This is not an official Ubuntu package.
