Find the display

[Christian Marillat <marillat.christian@wanadoo.fr>]

Hi,

I need to restart sawfish.

I use : sawfish-client -f restart

But the postinst say:

can't connect to display: -f

Indeed DISPLAY is always empty.

I really need to call sawfish-client with display.

I can't use display=:0.0 because this doesn't work if display <> :0.0

This doesn't work if I call sawfish-client with su $user, where $user is taken
from a ps.

Any ideas ?

Christian
