- Ubuntu gets stuck in a login loop 46 answers
I know there are already several questions about this problem. However, I did not find a solution using the answer already provided.
I just installed Ubuntu 14.04 LTS dual-boot alongside Windows 8. When logging in to Ubuntu using the login manager I am stuck in a log-in loop where I find myself at the beginning again after a black screen in between.
What makes this really difficult for me is that the computer does not have an internet connection and it will take a while until this will be possible. So I cannot install any updates or new applications.
I already tried to create a new (root) user, I changed permissions of my home folder or the /tmp folder, I changed permission of .Xauthority (which worked at first but after a reboot I have the same problem again and changing permission of .Xauthority does not help anymore), changed permission of .IDEauthority (I also tried just moving .Xauthority or .IDEauthority to a different file), restarted lightdm or rebooted the whole system. Also, .xsession-errors does not show any error message.
Not sure if this is helpful, but the system has an nvidia Quadro K2200 and it is apparetly running with the nouveau driver (at least according to "lshw -C display").
Any other ideas? Do you think I can solve this without internet access?
Thanks in advance!
