-

hi,
m working in project, want start opencv-python program on raspbian startup. program such open picamera , image processing , display in full-screen mode. did adding command "python filename.py" @ end of file .bashrc.
, set pi boot cli (command line interface). after rebooting shows errors

code: select all

final:920: gtk-warning**: cannot open display:


how can fix it?
please me.
in advance

opencv depends on having running x-windows server, cant use "boot cli".
need let x-server (desktop) start before can start program.
