Xubuntu 14.04 – screen shots

Posted on by

If you are using xubuntu 14.04 then pressing print screen takes a screen shot of the WHOLE screen,  this is fine in some cases but gets a pain if you want to write documentation or want to grab an application window.

The solution is to change thekey bindings

settings

Click on Settings manager

settings-search

Search for keyboard

settings-keyboard

Click the short cuts tab

settings-keyboard-shortcuts

You then get a screen like the one above.   if you look at

xfce-screenshooter -w (-w means window)  by default this is set to Alt-print screen to trigger.  I have already changed it, so click where it says Alt-print and change it to print. you may have to change the one above to something else otherwise they clash.

Press close and when you press print screen it should grab the current window.

Exeter Pi jam – 22/02/2014

Posted on by

As always an excellent mix of social activity,  techy talk and great demos.

Highlights are illustrated below with photos.

Over 1/2 term.  Exeter library hosted an event for children that used the raspberry pi camera to make a video of a puppet theatre.   The top photo was of a screen displaying the result of this work.  It looked pretty good and all achieved with the help of the PI.

Tom Brough recently aquired a doodle bot,  which is using an Arduino based system to draw.  The picture is of the bot, the holder at the front is for the pen.

A pi set up.  This was used by several people through out the event, python programming,  and by myself to give a quick demo of scratch.

The chimer, which will be familiar to regular pi jam visitors has now been expanded further.

This is another ones of Tom Broughs projects,  Helicopter game, which was also demoed at the Torbay jam.  This has now been set up on my pi too,  but Tom helped me get bluetooth support up and running.

As mentioned,  hopefully see more people at the next event,  you never know who will come or what will be demoed, and as a result you could mis out on some real gems of projects.

Next Exeter jam is 22nd March,   The next Torbay Jam is 8th March ( please see the previous jams page for a write up of the Torbay Pi jam for Feb.)

See you at the next jam.
