linux - Unable to run X11 (graphical) programs from atd -

i trying schedule execution of shell-script linux tool "at". shell script (video.sh) looks this:

#!/bin/sh /usr/bin/vlc /home/x/video.mkv

the "at" command:

at -f /home/x/video.sh -t 201411052225

when time arrives, nil happens.

i can execute shell-script fine via console or rightclicking - execute. vlc starts supposed to. if alter script e.g. simple like

#!/bin/sh touch something.txt

it works fine.

any ideas, why "at" not execute script starts graphical program? how can create work?

you're trying run x command (a graphical program) @ scheduled time. extremely difficult, , quite fragile, because script won't have access x server.

at least, need set display right value, then, suspect have issues authorisation utilize x screen.

try setting :0.0 , see if works. if you're logged out, or screensaver's on, or number of other things...

(also, redirect vlc's stdout , stderr file can see went wrong.)

your best bet might seek xuserrun.
