description |
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).

[ Description ]
Due to a refcounting bug, a GDBusConnection was getting disposed when it was still required. The symptom of this was that you couldn't log in if you'd got your password wrong.
[ 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.

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).

[ Description ]
Due to a refcounting bug, a GDBusConnection was getting disposed when it was still required. 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.
[ 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.
