Hi, > After execution of the "start-xephyr.sh" file at prompt > (outside of scratchbox), It is showing the below error: > : invalid option. It would seem that there's a problem with this script (or you're e.g. running some other shell than Bash). How did you copy the script? If you run the script line by line in the schell, from which line the error message comes from? - Eero
