Ubuntu: Upgrade failed for the Ubuntu 14.04 [duplicate]


I upgrade Ubuntu from 13.04 to 14.04,and my notebook now does not accept the upgrade and keep getting this message :

The system running in low - graphics mode.Your screen,graphics card,and input device settings could not be detected correctly.You will need to configure these yourself  

And when i click ok it takes me into a white board and can not write anything.My question is,what can i do to return back to 13.04 version?


You can't upgrade 14.04 directly from 13.04.

First you upgrade into 13.10 then upgrade to 14.04 LTS.
