Nothing there either > Hello Rustom, You're right, the man page of Xephyr doesn't provide a lot of info as Xephyr doesn't have that much options by itself. So the Xephyr man page being informative almost sounds cynical, sorry about that, not my intention. I got the usage info of this parameter from Xephyr --help, TinyX section. then I found out it didn't work for me so I started googling and came upon setting this specific option which works in my case. > Anyway for now I am dropping the keybd and session call and that runs. > Script is: > > #!/bin/bash > #set -x > # Set up nested X server > Xephyr -ac -screen 1024x768x16 -host-cursor -br -reset -terminate 2> > /dev/null :2 & > sleep 3 > export DISPLAY=:2.0 > #xfce4-session& > > I am now at the point of calling the second script.
