Thats an old error fixed posted some time ago. From memory,
The fix was to issue visudo from a terminal and add user knoppix,
post back if you still have trouble.
Whe I try to open a configuration application or something that requieres root, I get this error.
But "su" is installing and working, within terminal off course.
Any Idea ??
my box:
Code:Knoppix 5.1 on HD. root@linux:/dev# uname -a Linux linux 2.6.19 #7 SMP PREEMPT Sun Dec 17 22:01:07 CET 2006 i686 GNU/Linux
