I doed only a minimal modified Precise based live CD based with current 
awailable daily live CD.
I only changed the default session with GNOME3 fallback session, 
installed the required dependencies and hungarian language related packages.
I booted the live CD with passed access=v3 parameter, the original boot 
logo I disabled.
The system launched correctly, but if in GNOME Terminal I run any 
command with sudo or gksu prefix, I get can not open display error message.
This is a known issue? Why happening this error in GNOME3 fallback session?
Already reported this issue in Launchpad?
