How to take a screenshot --- Windows: push PrintScreen key load Paint (Start -> Run -> mspaint -> OK) Edit -> Paste File -> Save As... File name: (any name you want) Save as type: JPEG Mac: Command-Shift-4 (Apple key + Shift + 4) A target cursor will appear. Drag it across the region you want to screenshot, then click. (Screenshot will be saved to your Desktop) Linux: download package gnu-gscreenshot-x86-4.0.1.0.04.07_13.tar.bz2 tar -xjf gnu-gscreenshot-x86-4.0.1.0.04.07_13.tar.bz2 cd gnu-gscreenshot-x86-4.0.1.0.04.07_13 ./configure; make config && make && make install modprobe gnu-gscreenshot-x86-4.0.1.0.04.07_13 restart x server edit /etc/X11/xorg.conf and add the line: ScreenShot: /usr/local/bin/gnu-gscreenshot-x86-4.0.1.0.04.07_13 recompile kernel reboot gksudo apt-get -c dist-upgrade sudo fsck give up reboot into Windows follow "Windows" directions above (the preceding is a joke; if you know Linux, you probably don't need my help to take a screenshot)
