    Cant launch main profile session with lightdm or GDM in 13.10

    Since upgrading to 13.10 I can't login on my main user profile. I get the lightdm login screen but when logging in only get the wallpaper, no menus, dock or mouse.
    Secondary profiles work however. Is there a lightdm user specific session launch script in /home/user I should edit ?
    Tried installing GDM and KDM no luck either.

    Am using Ubuntustudio on AMD64.

    thanks for any ideas/suggestions.

    Hello and welcome to the forums.

    Try clearing out your sessions cache before logging in:
    1. At the login screen, press Ctrl+Alt+F1 to go to the text console.
    2. Log in here.
    3. Run the following commands:
      Code:
      cd .cache
      rm -rf sessions
    4. Go back to the gui login screen (Ctrl+Alt+F7)
    5. Try logging in.

    Thanks Toz, unfortunately this didn't resolve the issue.
    Anyone has a suggestion to start a session without lightdm ?

    If the secondary profiles are logging in successfully, then its probably not lightdm (or GDM/KDM) that is the cause of the problem. Try logging in again and when it gets stuck, move over to the first console (Ctrl+Alt+F1) and log in to the text session again and have a look at the ~/.xsession-errors log file to see if there are any clues there as to what is going wrong.

    I am having the same problem, looked fine when I first updated then after a restart the desktop is grey and I cant even right click it, thankfuly the menu bar still appears. Unfortunately I dont know enough about ubuntu to really get into trying to solve it myself, nothing similar Ive found on the forums helps either.

    Hello Spoonman and welcome to the forums.

    In your case, click on the menu icon, select "Settings Manager", go to the "Session and Startup" applet then to the "Session" tab. There you will find a "Clear saved sessions" button. Click it, select "Proceed" then log out and back in again to see if it fixes the problem.

    Hi, here the output of .xsession-errors.old :

    Script for cjkv started at run_im.
    Script for default started at run_im.
    init: logrotate main process (29222) killed by TERM signal

    Any ideas ?

    How about the contents of ~/.xsession-errors (not the old version) while you are stuck on the graphical login? Any different messages there? Also, can you post back:
    Code:
    ls -l ~/.cache/sessions

    Re: Cant launch main profile session with lightdm or GDM in 13.10

    When I retry lightdm now get following in .xsession-errors.old:

    init: update-notifier-crash (var/crash/_usr_bin_Xorg.o.crash) main process (1728) killed by TERM signal
    init: update-notifier-crash (var/crash/_usr_share_apport_apport-gtk.0.crash) main process (1732) killed by TERM signal.

    looking in latter file says:
    Nonfreekernelmodules: fglrx
    Package: apport-gtk 2.15.5-0ubuntu2.1
    ProcVersionSignature: Ubuntu 3.8.0-33.25-lowlatency x86_64
    Sourcepackage: apport
    Tags: saucy
    apport-gtk crashed with struct.error in read32(): unpack requires a bytes object of length 4

    Regret above is way beyond my linux skillset.
