Cannot show image display windows in openCV

Question

I am using python openCV bindings. I am trying to show the output image using the following list:

cv.NamedWindow('display')
cv.MoveWindow('display', 10, 10)
cv.ShowImage('display', cvImage)

But I do not see any window.

My platform is Linux (openSuse 11.4), python-opencv version 2.1 and python 2.7.
