Probably the problem is with X authorization, DISPLAY variable is not enough. In my scripts I do something like this: export XAUTHORITY=/home/users/$USER/.Xauthority export DISPLAY=:0 export QT_X11_NO_MITSHM=1 # don't now if xrandr needs this, probably not and then xrandr and other commands work. But these are bash scripts. You have to probaby do something similar. -- Łukasz Maśko _o) Lukasz.Masko(at)ipipan.waw.pl /\\ Registered Linux User #61028 _\_V Ubuntu: staroafrykańskie słowo oznaczające "Nie umiem zainstalować Debiana" _______________________________________________ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
