Then I have tried it from terminal, then I got those error massage. –Apurba Aug 15 '12 at 13:21 As in a terminal within the graphical user environment? What does: echo $DISPLAY say? You should run it without sudo as super-boot-manager runs sudo internally. –Thor Aug 15 '12 at 15:23 echo $DISPLAY is giving :0.0. And I am not running super-boot-manager as sudo. I am running just using command super-boot-manager from terminal. –Apurba Aug 16 '12 at 19:36 1 Finally the problem is solved. I have just added the line: Defaults env_keep="DISPLAY XAUTHORITY" at the end of visudo. Thanks to all, specially @Thor for kind help. –Apurba Aug 17 '12 at 8:03 | show 4 more comments 2 Answers 2 active oldest votes up vote 18 down vote accepted You need to allow the root user access to the X server: xhost local:root And point

But :0.0 does indeed exist and I've even tried disabling X authentication in case Eclipse is spawning it in a weird and wonderful way.... no dice.
