Проблема с Authentication failed

Здравствуйте,

При запуске X из под непривилегированного пользователя получаю ошибку:
Authentication failed - cannot start X server.
Perhaps you do not have console ownership?

Подскажите пожалуйста как с этим бороться. Единственное что я нашел по теме (покрайней мере мне так кажется) это файл /etc/security/console.perms. В моей системе он выглядит так:

# /etc/security/console.perms
#
# This file determines the permissions that will be given to priviledged
# users of the console at login time, and the permissions to which to
# revert when the users log out.

# format is:
# <class>=list of regexps specifying consoles or globs specifying files
# file-glob|<class> perm dev-regex|<dev-class> \
# revert-mode revert-owner[.revert-group]
# the revert-mode, revert-owner, and revert-group are optional, and default
# to 0600, root, and root, respectively.
#
# For more information:
# man 5 console.perms

# file classes -- these are regular expressions
<console>=tty[0-9][0-9]* vc/[0-9][0-9]* :[0-9]\.[0-9] :[0-9]
<xconsole>=:[0-9]\.[0-9] :[0-9]
