[Freegis-list] how I can make the screen shot?

[=?gb2312?B?uLUgwek=?=]

Hi, there
I'm prepareing a ppt focus on GIS-Knoppix right the momnent.
But I found out that I can not make screen shots as it's a liveCD.
I tried several methods, but there is no internet connection when using 
this CD,
and usb is not working neither.

Somebody has a good idea?

Thanks a million before hand!

Best Regard,
Lynn
