I use both Ubuntu Linux and Windows 7 and fairly happy with the built in screen capture tools in those OS environments. The one comes in Ubuntu is different from the one in MS Windows and some features in Ubuntu’s tool aren’t included in MS Window (vice versa).
For instance, Windows 7 does not grab your mouse pointer but has a built in “painting” app that lets you edit your screenshots with some decent amount of options. Where in Ubuntu, though it captures the mouse pointer and even lets you set delays etc but, unless you install a utility manually (I use “XPaint“), you can’t really edit your screenshots (other than cropping or resizing).
In that sense, if you’re looking for a screen capture tool that gives you a decent amount of options (including an inbuilt image editor) but still retaining a simple and user friendly UI, then you might wanna try “qscreenshot”. It’s an open source (GNU GPL v2 licensed), completely free utility that runs in GNU/Linux, Windows and Mac OS X.
But please remember it too does not support capturing the mouse. But if you’re okay with that, then it is still a great tool.
Few main features …
*. You can capture the whole screen, currently selected window or can even manually select an area.
*. Add delays.
*. Change the keyboard shortcut (default is: “Ctrl” + “Shift” + “s”).
*. For that keyboard shortcut to work, “qscreenshot” has to be running in the background. When you open it once, it stays in your notification area until you exit it or reboot your PC. But it has an option that lets you start it automatically when the desktop is loading too.
*. As mentioned above, it has a few built in tools for basic image editing such as: a Pencil (with the ability to change the line thickness and color), add Ellipses and Rectangles, Select tool, Cut/Copy/Paste, Undo, Rotate, Blur and add Text (including changing font, size etc).
*. Lets you upload images to several online sources.
It has pre-built packages for Ubuntu/Debian/Fedora, Windows and Mac OS X. So if you want to give it a go, then please get the appropriate package from this “qscreenshot’s” download page.
Get the “.deb” package if you use Ubuntu and double click on it after downloading to install (then follow the on-screen instructions). It installed without any issues in Ubuntu 11.10 Oneiric Ocelot but I don’t know if it would work on other versions though.
