13.04 login loop, no .xauthority

**Crossbow** · August 18th, 2013

Regarding the capitalization, I had to type in that output because I can't copy-paste from the virtual terminal, so that is a typo of mine, not the name of the file. I did the

Code:

chown anna:anna .Xauthority

but nothing happened and nothing changed.

I saw that on several threads it was recommended to remove .Xauthority, so now it is just gone. Seems to make no difference. Do I need it? How do I get it back?

I now believe this is a lightdm problem. Someone said he solved this by installing gdm, making that the default, logging in, and then changing the default back to lightdm. I did that, and I COULD log in with gdm, but when I switched back to lightdm I was back to the same login problem.

This post has a recommendation to uninstall and reinstall lightdm. Should I try that? Do I just remove it? Do I also purge it?

Tried apt-get install --reinstall lightdm. Seemed to work, no errors, but did not fix the problem.

By changing the default from lightdm to gdm, I am able to log in, but I don't like it. I find it slow and harder to navigate. I tried reinstalling lightdm to no avail. Also reinsalled ubuntu-desktop and nvidia-173, which is the last version of nvidia that worked at all for me. (I should theoretically be able to use 3.10 but when I change to that I lose my GUI altogether.)

The latest on .Xauthority:

Code:

anna@anna-desktop:~$ sudo chown anna:anna /home/anna/.ICEauthority
anna@anna-desktop:~$ sudo chown anna:anna /home/anna/.Xauthority

No change.

apt-get update does the usual and then ends with this:

Code:

W: Duplicate sources.list entry http://us.archive.ubuntu.com/ubuntu/ raring/restricted i386 Packages (/var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_raring_restricted_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems

Which has been going on longer than the login problem has so is probably not related.
