Probably because your question is very unclear. We can't see your screen so you need to be much more specific than "only gnome-flashback option". Did you install gnome? How did you upgrade? What was the last desktop environment you logged into? etc. – Seth Apr 30 '14 at 16:42
Last desktop environment was ubuntu 13.10 (develpoment branch called as aplha or beta version of ubuntu). and i did not install gnome . I just upgrade Ubuntu 13.10. – ABPrime Apr 30 '14 at 16:45
and i report bug at launchpad . see the link – ABPrime Apr 30 '14 at 16:47
