import -window root on CentOS 7 just gives beep beep

[jgeis]

Hi all,

I have CentOS 7 and would like to get a screen capture of the whole screen.
When I do the following:
export DISPLAY=:0.0
import -window root screen.png

All I hear is beep beep and no errors reported and the screen.png file is all black.

This command works fine on CentOS 6.

CentOS 7 has version 6.7.8.9-15

What am I not doing correctly?
Thanks,

Jerry
