Screenshots are vital when reviewing an application or giving visual assistance to those problems whose solution is difficult to jot down in words. For starters, when you press the ‘Prt Scr’ i.e. ‘Print Screen’ keyboard button the computer will automatically print what is currently being displayed on the screen & prompt you to save it as a file. The Screenshot application found under GNOME provides further options to finetune screenshot capturing as per your needs. While this will work fine when you’re running under a GUI but what would you do if you want to take screenshot when you are in a shell(virtual console) or when your GUI is broken? The print screen button on your keyboard won’t work in at the command prompt. In such a case you’ll need to use the following command.
$ import -window root /home/ShutterTux/Pictures/screenshot.png
The above command will save the screenshot of the current screen without any delay into the ‘Pictures” directory of user ‘LaymanLinux’ with the file name as ‘screenshot.png’. The file saving location need not be necessarily pictures directory & you can give any location in your home directory. Do remember to change the name of the output screenshot file to avoid conflicts.
You can even issue the command with a delay;
$ delay 20; import -window root /home/ShutterTux/Pictures/screenshot2.png
The above command will take screenshot after 20 seconds and save it to the location entered by the user.

GNOME desktop has been completely revamped in its new avatar, the GNOME 3. All the changes till now have made it more usable than before. I’m quite liking the new desktop but there is one thing that annoys me big time. Where is the shutdown button? I couldn’t find it anywhere. Is there any keyboard shortcut or mouse gesture to shutdown the desktop? I quite literally, shutdown my computer from the virtual consoles by issuing an ‘init 0′ command for some instances till I figured out the shutdown button is indeed present but not visible(as it was in testing releases of GNOME 3).
To shutdown the computer when using GNOME 3, you need to click on your user-name in the far right top corner of your screen. Upon clicking you’ll get the regular drop-down menu, with the last option as ‘Suspend’. Now press the ‘Alt’ key on the keyboard & keep it pressed and voila the ‘Suspend’ option magically turns into ‘Power Off…’. Upon clicking, you’ll get to choose between a system restart & shutdown.
There you have it. I don’t know why the GNOME team decided to make it so mysterious. GNOME has always been a user-friendly desktop environment but such moves may make its users turn to other alternatives. Already some users have expressed their annoyance to the new changes of the GNOME 3.
