Gnome nenastartuje - cannot open display

Dobry den, po poslednim upgradu meho gentoo se gnome pri startu jednoduse kousne. Prihlasim se pod svym uzivatelem pres gdm a potom uz vidim jen sedivou obrazovku. Soubor .xsession-errors:

/usr/X11R6/bin/xsetroot:  unable to open display ':0'
/etc/X11/gdm/PreSession/Default: Registering your session with wtmp and utmp
/etc/X11/gdm/PreSession/Default: running: /usr/X11R6/bin/sessreg -a -w /var/log/wtmp -u /var/run/utmp -x "/var/gdm/:0.Xservers" -h "" -l ":0" "martin"
/etc/X11/gdm/Xsession: Beginning session setup...
/etc/X11/gdm/Xsession: Setup done, will execute: /usr/bin/ssh-agent -- gnome-session

(gnome-session:17120): Gtk-WARNING **: cannot open display:

Nevite kde by mohl byt problem? Predem dekuji za odpovedi....
