Seems Filemanager Super User, has gone for the start menu of 2010.
However typing konqueror su in the console produces this error "Protocol Not Supported"
From consol su typing konqueror su produces this error
No protocol specified
konqueror: cannot connect to X server :0.0
Same thing happens when trying to use Dolphin.
I'm sure there is a simple way to get a filemanager running as root.
