Xubuntu 13.04 X Login Loop
Solution 1
The following solved the problem:
mv ~/.config ~/.config.old
So it looks like the problem was with some desktop setting, somewhere.
Now, of course, my desktop is reset for apparently no good reason. Is there an easy way to find the corrupted config file(s)?
Solution 2
In my case login was possible again after removing $HOME/.Xauthority :
- Press
<ALT-Control-F1>
and you get an ASCII login. Enter username and password. - Type
rm .Xauthority
. Then you can go back to the graphical login screen by pressing<ALT-Control-F7>
.
After taking a closer look it appears that the contents of .Xauthority are destroyed by sshd when login in from a remote machine:
before ssh-ing from a remote machine:
ls -l .Xauthority
rw------- 1 ubuntu ubuntu 50 Nov 24 18:46 .Xauthority
after ssh-ing from a remote machine:
ls -l .Xauthority
-rw------- 1 ubuntu ubuntu 101 Nov 24 19:22 .Xauthority
What can be seen is that the file has an odd number of bytes after the ssh-login.
Maybe there are more programs besides sshd that damage .Xauthority.

All of a sudden, I am no longer able to login to an X session in my Xubuntu 13.04 install. The graphical login accepts my password, the screen goes blank and then returns to the login prompt. A bit of Googling tells me that this isn't an uncommon problem, but all the advice I've read so far hasn't worked:
- I can login to the guest account, so the login manager is working.
- I can login to my account via tty or ssh, so my account isn't locked.
- I can start applications through an X tunnel (XMing+PuTTY), if that's relevant.
- There's masses of disk space left.
- My
~/.Xauthority
is owned by me, rather than root. - There's no reference to
~/.ICEauthority
in my logs and the file is otherwise owned by me. /var/log/Xorg.0.log
looks OK(ish): There are a few warnings about missing fonts and complaints aboutpsb
. Apparently that's the video driver (my laptop uses Intel GMA500) and there are similar complaints later in the file, however it ultimately settles on something. After all, the display is clearly working at the login screen (as it is for the guest account).There are some errors and permission complaints in
~/.xsession-errors
, but I'm not sure if they're relevant:ERROR:root:Could not find any typelib for Dbusmenu ERROR:root:Could not find any typelib for Unity ... ###!!! [Parent][RPCChannel] Error: Channel error: cannot send/recv ... debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Permission denied
- I tried
dpkg-reconfigure xubuntu-desktop
andapt-get -y install xubuntu-desktop
to try refreshing/reinstalling, but neither option seemed to do anything.
Therefore, I'm kind of at a loss! So any ideas would be most appreciated!

elf12 over 10 yearsI had this problem with new Xubuntu 13.10 after unplugging a second display at my Laptops vga-out and restarting. In my case
rm ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml
did it! -
Adrian Keister over 10 yearsJust to confirm: I had the same problem as elf12, and the command given worked for me. However, through some weird trick of my browser, it looked like there was a space in the command right after the 'l' of channel. So, note to users of this command: there are no spaces after the 'rm'! I recommend putting this command into your ~ folder as a bash shell script, so it's easy to ctl-alt-f1 into the cli, execute the bash shell script, and then ctl-alt-f7 back into the gui.

David Foerster over 9 yearsAU values and encourages high-quality answers. As it stands, your answer is not very useful, because a reader cannot understand how to identify such a “corrupted file”. To improve your answer can you please describe, what you did exactly?

Minix about 8 yearsThis solved the problem for me, after trying every other method found here or elsewhere. I don't know either, how to identify the offending file. I just deleted all the unimportant files on my desktop and luckily that worked. No need to change
.Xauthority
,.ICEblabla
, no need to delete anything in the.config
dir. Thanks, Absintu, for writing the answer, even though it's not that elaborate. -
Till Kolditz almost 5 yearsHi, this happened to me also in Xubuntu 18.04.2. Not only the
.Xauthority
file, but also other files were suddently owned by root:root. Does anybody know why this happens? Thx!
