Can you login in the console?

If yes, try to move your .bashrc. At least for me, that solved the problem. But to be more accurate, check your .xsession-errors also...

Status changed to 'Confirmed' because the bug affects multiple users.

[Peter Antoniac (pan1nx)]

The other way around is to boot from CD/USB, mount the disk with the home and then look into your .xsession-error

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command, as it will automatically gather debugging information, in a terminal:

apport-collect 1069283

This will help us to find and resolve the problem. Bear in mind that you may need to install the python-launchpadlib package from the universe repository. Additionally, when prompted to give apport-collect permissions for Launchpad you will need to give it at least the ability to "Change Non-Private" data as it will be adding information to your bug report. Thanks in advance!

When reporting bugs in the future please use apport, either via the appropriate application's "Help -> Report a Problem" menu or using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Done. I tried logging via tty and moving my .bashrc as well, but that
didn't resolve the issue.
I can upload whatever logs are needed, I just don't know how.

Thank you for your patience...

Did you check the .xsession-errors file in your home directory (of the user that you try to log in)?

That might give you and us a clue to what is going on there behind the scenes.

Thanks!

I did, but I have no idea how to read it. Is there a way that I can
upload it to launchpad from the command line?

[Peter Antoniac (pan1nx)]

Apport-collect with add information...

Here's the relevant .xsession-errors file

[Peter Antoniac (pan1nx)]

Thanks for reporting this bug and supporting logs. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

But still, you could also try to login using a new user. If it works, it might be that your session information is the cause and not the Dispaly Manager.

It's actually been crashing before I'm able to try to log in. I think
it's crashing when LightDM starts.

[Ian Nicholson (imnichol)]

As of yesterday, my updated system does not bring me to the login screen. I am able to log in from a terminal, but lightdm doesn't start.

[Ian Nicholson (imnichol)]

I am still experiencing this bug, but I installed GDM which gives me a graphical login so I can at least get to my desktop. There is still a 2 or 3 second period where I still see glitched text on VT7 before GDM takes over though.

@imnichol is this bug fixed with the nouveau drivers?

Otherwise bug 1093376 is probably not a dupe of this bug

No, it is not fixed with nouveau.

[graingert (tagrain)]

bug 1093376 is probably not a dupe of this bug then

I managed to get rid of the problem by deleting .Xauthority (got the tip from another bug report IIRC). It seems that owner of the problematic .Xauthority is root, whereas the owner of the new .Xauthority is the user. Could it be a file access issue?

I've tried this, and I don't think it always fixed the problem permanently.
