Ubuntu

cannot create /dev/null: Permission denied

Asked by mau on 2007-11-02

Dear Sirs

After upgrade from feisty to gutsy I can't login from the graphical interface. After accepting my password, the display flickers and returns to the login screen. There are no error messages. If I go to console login and try startx this fails and shows two relevant messages: "/etc/X11/Xsession: 92: cannot create /dev/null: Permission denied" and "/usr/bin/startx: line 169: /dev/null: Permesso negato". If I start in recovery mode I login with my username and my password but without my configuration. Note: no problem on Feisty.
Please help me.
Thanks in advance for your attention.
Best regards.

Sorry if I answer with another question.
Yes, your suggestion solve the problem and now I can login with my username and password.
Unfortunately sudo don't works because if I try sudo <command> and I answer with my password, the system refuse the password.
Could you help me?
Thanks a lot in advance.
