Question on /usr/bin/import for CentOS 7

[Jerry Geis <jerry.geis@xxxxxxxxx>]

Under CentOS 6 I could run the command:
/usr/bin/import -window root screen.png
to get a screen capture - worked great.

On CentOS 7.2.1511

when I run the above command I hear beep beep
and the resulting screen.png is just black.

Two questions:
1) how can I get the screen shot?
2) how can I disable the beep beep

Thanks,

Jerry
