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
Ok - I thought maybe the beep was due to error - but apparently not. I have found how to disable the beep with the -silent option However - I am still not able to get a screen shot - it resulting png is just black or black. export DISPLAY=:0.0 import -silent -window root screen.png the file is just all black. Thoughts? Jerry

Yes I am running as root. If I try as a user I get the same behavior. Two things here. If on my desktop in a gnome window I run "import -silent -window root screen.png" I get a file. However if I run the command using a shell script on a machine its not working. So in my script I have: export DISPLAY=:0.0 /usr/bin/import -silent -window root screen.png Thanks, Jerry
