Public bug reported: I ticked autologin when installing Ubuntu Studio 21.04. Autologin did not work. Trying to enable through Settings - System Settings - Startup and Shutown - Login Screen(SDDM), Behaviour button, caused a DBUS error message about SDDM Config.
The fix is simple. Remove all lines from /etc/sddm.conf file and reboot. All functionality correct after that. It seems autologin configuration is only through /etc/sddm.conf.d/kde_settings.conf Additionally, removing all lines from /etc/sddm.conf file also restored correct functionality to the above-mentioned System Settings Startup and Shutdown section (Sddm Config Manager is then able to successfully modify kde_settings.conf ProblemType: Bug DistroRelease: Ubuntu 21.04 Package: sddm 0.19.0-2ubuntu1 ProcVersionSignature: Ubuntu 5.8.0-36.40+21.04.1-lowlatency 5.8.18 Uname: Linux 5.8.0-36-lowlatency x86_64 NonfreeKernelModules: prl_fs_freeze prl_fs prl_eth zfs zunicode zavl icp zcommon znvpair prl_vid prl_tg ApportVersion: 2.20.11-0ubuntu57 Architecture: amd64 CasperMD5CheckResult: unknown Date: Fri Feb 5 02:07:17 2021 InstallationDate: Installed on 2021-02-04 (0 days ago) InstallationMedia: Ubuntu-Studio 21.04 "Hirsute Hippo" - Alpha amd64 (20210203) SourcePackage: sddm UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: sddm (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug hirsute -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1914613 Title: Autologin not working in Ubuntu Studio 21.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sddm/+bug/1914613/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
