I have installed tomcat 8 and shutdown my laptop. Now when I start it after login it doesn't show anything. Right click is also disabled and only the splash screen appears with wallpaper. I'm using Ubuntu 15.10. When I log in to a guest session, my own user or gnome desktop the same thing happens.

What could be the problem and how can I fix it?

    On login screen you can access tty by pressing Ctrl+Alt+F1. To exit press Ctrl +Alt+F7 – Olimjon Feb 14 '16 at 09:43

  • @mark when I am applying first command it says error "cannot autolaunch D-Bus without $DISPLAY" because Display variable not set – Drashti Pandya Feb 15 '16 at 11:24
  • Drashti - you need to ask @ashu about this solution, I did not write it, I am sure he can help, this comment will notify him. – Mark Kirby Feb 15 '16 at 16:14
  • @DrashtiPandya. Please refer to this thread 'http://askubuntu.com/questions/289719/cant-get-xterm-to-work-display-not-set' regarding display. In my case 'echo $DISPLAY' gives this output ':0'. – Ashu Feb 15 '16 at 17:12
  • @ashu have set display variable to 0.but error is spawing command line 'dbus-lunch--autolaunch' child process exit with code 1 – Drashti Pandya Feb 17 '16 at 05:25
  • @DrashtiPandya. Refer this thread 'http://askubuntu.com/questions/323776/gsettings-not-working-over-ssh' – Ashu Feb 17 '16 at 05:29
