Unable to login without logging into the terminal first

[Stephen Rees-Carter]

Ok, it turns out removing the .dmrc file isn't the cause of my logins working:

I removed it yesterday while I was logged in and shutdown my computer. Today I switched my computer on and the login screen, again, wouldn't let me in. I jumped into terminal to remove the .dmrc file, only to discover that it wasn't there. I went back to the login screen and this time it let me straight in.

So it looks like simply logging into the terminal allows the login screen to work...

OLD:
After a recent dist-upgrade, I have been unable to login without first deleting the .dmrc file within my home directory.

What sort of information & logs do you need to help debug this?

Same issue occurs for me on every boot of an up to date Oneiric x86_64 install. After the lightdm login screen is displayed I enter my username and password hit login, the login screen disappears briefly before reappearing, The same happens with what ever session type I choose, for example Gnome3 or Unity. If I switch to a virtual terminal and login first I can then switch back to lightdm and login normally. This has been happening for about a week.

What can I provide to help track down the cause of the issue? I'm attaching the output of lspci and lightdm logs.

[f1anker (ianspigeon)]

After tonights updates I can now login directly via lightdm without having to login via a terminal first.

No longer an issue for me.

Same thing here. After an update start to work properly.

[Dave Russell (drussell)]

Same here. Will see if I can set it to "fix released", if anyone's still affected, please shout out.

If you are having problems logging onto the new Ubuntu 11.10. Then give this a go:

Press "Ctrl+Alt+F1"
login
sudo chmod 777 -R /tmp
sudo reboot

we have 3 machines with this problem. we have had a go with most of the post that people have published.
What fixed it for us (bad practise I know, but for now we can login)
