This bug was fixed in the package gdm3 - 3.28.2-2ubuntu1 --------------- gdm3 (3.28.2-2ubuntu1) cosmic; urgency=medium
[ Iain Lane ] * Merge with Debian. Remaining changes: + README.Debian: update for correct paths in Ubuntu + control.in: - Don't recommend desktop-base - Depend on bash for ubuntu_config_error_dialog.patch - Update Vcs field + rules: - Don't override default user/group - --enable-gdm-xsession to install upstream Xsession script - override dh_installinit with --no-start to avoid session being killed + rules, README.Debian, gdm3.8.pod: Use upstream custom.conf instead of daemon.conf + gdm3.{postinst,postrm}: rename user and group back to gdm + gdm3.postinst: don't kill gdm on upgrade + gdm3.*.pam: Make pam_env read ~/.pam_environment + gdm3.install: - Stop installing default.desktop. It adds unnecessary clutter ("System Default") to the session chooser. - Don't install debian/Xsession + Add ubuntu_run_xsession.d.patch + Add ubuntu_xresources_is_a_dir.patch - Fix loading from /etc/X11/Xresources/* + Add ubuntu_nvidia_prime.patch: - Add hook to run prime-offload (as root) and prime-switch if nvidia-prime is installed + Add revert_override_LANG_with_accountservices.patch: - On Ubuntu accountservices only stores the language and not the full locale as needed by LANG. + Add ubuntu_dont_set_language_env.patch: - Don't run the set_up_session_language() function, since it overrides variable values set by ~/.pam_environment + Add ubuntu_config_error_dialog.patch: - Show warning dialog in case of error in ~/.profile etc. and don't let a syntax error make the login fail + Add debian/default.pa - Disable Bluetooth audio devices in PulseAudio from gdm3. + debian/gdm3.install - Added details of the default.pa file + debian/gdm3.postinst - Added installation of default.pa and creation of dir if it doesn't exist.

The symptom of this was that you couldn't log in on the second attempt if you'd got your password wrong on the first attempt. All you'd see is a blank purple screen and mouse pointer only. [ Test case ] 1. Boot to GDM 2. Click your username 3. Type the wrong password a couple of times, pressing enter after each time 4. Type the right password If the bug is happening, after 4. the system hangs at a blank screen with the mouse cursor. If you then switch to a VT or otherwise connect to the machine, you can examine the journal and you'll see a G_IS_DBUS_CONNECTION failure. [ Fix ] Marco and I worked upstream on this fix. We found out that there was a problem like this- The GdmClient has a shared GDBusConnection for its operations. The first time someone calls for it, it is created and stored in the object's private structure. Subsequent calls return *a new reference* to this same object. It turned out that the asynchronous method to get the connection was accidentally unreferencing its object before giving it to the caller if it was returning an already-existing connection. For this to work properly, we need to nullify the pointer we stored when the connection goes away, so we know when to make a new one. There were some cases where we didn't add the weak references required to do that. Those are also fixed. [ Regression potential ] Now we share connections more than we did before. We also more carefully track when to clear our object. If we got this wrong, we might end up leaking the connection or dropping it in even more cases. [ Original report ] WORKAROUND: After typing an incorrect password, click Cancel, then click your name, then enter your password again. --- Trying to log into my session (Gnome, Xorg), if I enter the wrong password before entering it correctly, the session doesn't load and I get a purple screen, a mouse cursor, and an invisible but clickable menu in the top right. If I enter it correctly the first time, there is no problem. I've replicated this from a fresh boot, after logging out and after 'sudo service gdm restart' from the Ctrl-Alt-F4 console. This is a fresh install, and didn't occur when I was using a previous install of 18.04 (until Friday).
