If you want to forward gui applicaitons back to yourself over ssh, remember to add the -X command to the ssh call. i.e. ssh -X userid@servername In the gdm login window configuration panel, make sure that you are allowing TCP connections to the Xserver if you are going to use XDMCP. I beleive it is set to deny by default. That setting is on the Security tab. As to the screen shots, Alt-PrtScrn is not really disabled, it's just not doing the same thing as you might expect from windows. It's actually activating the SysReq option, which tied with X, B, and a few other keys can do a number of things, including telling the kernel to reboot a system that otherwise is completely non-responsive. -Rusty <div class="gmail_quote">On Mon, Aug 3, 2009 at 9:22 PM, <<a href="mailto:ubuntu-us-mn-request@lists.ubuntu.com">ubuntu-us-mn-request@lists.ubuntu.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Send ubuntu-us-mn mailing list submissions to <a href="mailto:ubuntu-us-mn@lists.ubuntu.com">ubuntu-us-mn@lists.ubuntu.com</a> To subscribe or unsubscribe via the World Wide Web, visit <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-us-mn" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-us-mn</a> or, via email, send a message with subject or body 'help' to <a href="mailto:ubuntu-us-mn-request@lists.ubuntu.com">ubuntu-us-mn-request@lists.ubuntu.com</a> You can reach the person managing the list at <a href="mailto:ubuntu-us-mn-owner@lists.ubuntu.com">ubuntu-us-mn-owner@lists.ubuntu.com</a> When replying, please edit your Subject line so it is more specific than "Re: Contents of ubuntu-us-mn digest..."

I was a little surprised to find out that you can't do alt-print screens to capture just the active window like you can in Windows. Also, the Gimp can do various screen captures as well. Hope this helps, Dan |-----Original Message----- |From: <a href="mailto:ubuntu-us-mn-bounces@lists.ubuntu.com">ubuntu-us-mn-bounces@lists.ubuntu.com</a> [mailto:<a href="mailto:ubuntu-us-mn-">ubuntu-us-mn-</a> |<a href="mailto:bounces@lists.ubuntu.com">bounces@lists.ubuntu.com</a>] On Behalf Of Matthew Young |Sent: Sunday, August 02, 2009 5:36 PM |To: <a href="mailto:ubuntu-us-mn@lists.ubuntu.com">ubuntu-us-mn@lists.ubuntu.com</a> |Subject: Re: [ubuntu-us-mn] ubuntu-us-mn Digest, Vol 24, Issue 1 | | I was wondering, is it possible to take a screen shot of a browser |game with Ubuntu 9.04? |The game that I am talking about is ikariam.

I was looking for a ssh base solution. Perhaps this will work: VNC. The target system needs to be configured to accept remote control. This can be done via System|Preferences|Remote Desktop Preferences. The default is not to allow remote access. On Sharing section, allow others to view and/or control the desktop. On Security there are some options that apply. For example, confirmation could be set on, but that would not be appropriate if the target system was unattended. Or a password can be required to access the system remotely. When the Remote Desktop Preferences is set, the system can be accessed via Applications|Internet|Remote Desktop Viewer. I was able to connect between my laptop and server, but there were issues seeing the refreshed screen. I am not sure if it was that one machine was run gnome and the other was running kde. There appears to be remote control. But the results of the remote requests are not seen by the remote machine. Perhaps this due to the router settings. Anyway, good luck with this.
