I realise you've already said this isn't the answer you're looking for (having been linked to my question on the topic) but my scope is web development... Which is what you say you want to do. It's perfect for fleshing out page-level objects in a quick grid layout. Much more simple than a full graphics package, with various UI hints available as drag-on objects.
There's a deb package available for installation.

There is an app on APT called recordmydesktop (gtk-recordmydesktop with a graphical interface). Its very easy to use. You may also check this location and see what you prefer:

You could try to use VLC movie player which is available on apt but it may be outdated so get it from here:

It is possible to configure it so it will record your desktop/game or whatever you need.
