Bug Description
Description: Ubuntu 20.04.1 LTS
Release: 20.04
lightdm-
Installed: 2.0.8-1ubuntu1
Candidate: 2.0.8-1ubuntu1
Version table:
*** 2.0.8-1ubuntu1 100
100 /var/lib/
2.0.6-0ubuntu1 500
500 http://
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:
