I installed Ubuntu Gnome and did a lot of system configurations and installed all my programmes. Now once of a sudden the booting sequence hangs just before the login screen. If I hit Ctrl + Alt + Backspace I will get to the login screen. However, login just ends with a black screen and the desktop does not show.

I looked into https://askubuntu.com/a/223634. Accessed the terminal via Ctrl+Alt+F3 and tried the following:

  • ls -lah does not show .Xauthority
  • ls -ld /tmp seems to be okay regarding writing rights
  • dpkg-reconfigure gdm did not show any results
  • Even after killing X and login in, I can find .xsession-errors

Can you help me to debug this issue? Thanks.

Xorg.0.log output: http://paste.ubuntu.com/7418243/

One line says: [ 337.141] setversion 1.4 failed: Permission denied Does that hint to anything?

  • The classical files to look at are /var/log/Xorg.0.log (for problems before the login) and ~/.xsession-errors (after login). How much time are you waiting before killing the X server? Sometime gnome-shell dies on the login, and apport blocks my system for more than two minutes trying to collect data --- try a killall apport in the Virtual Console.

  • I can´t find .xsession-errors even after login in and landing in the blank. If I do killall apport it can not find the process. Please see log ouput above. What can I do?

Reset to default

I created a new user via the terminal and it turns out I could login with no problem with it. So I just went on and reset my own ~/.profile by renaming it. I then just had to redo all the gnome settings. Not ideal but it works at least again.

  • it's bad but out of desperation, I ended up doing the same - at least it works...
