Printscreen button not working on Gnome. I have to Run Shutter to make printscreen. Is there any tutorial to make it work with printscreen button?
It doesn't work in Older Versions of Unity or gnome classic, try updating the kernel. What version are you using 12.10 or 12.04 11.10 11.04 Lucid Lynx? If you're using version 12.04 it's very simple http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/ and download the correct ones for you arch like AMD64 or i386 or ARMS. Install them by the terminal:
cd Downloads sudo dpkg -i Linux*.deb
This will install all the files. This fixed many errors with my keyboard like the back-lit and NumLock and hr volume controls or try switching over to KDE Kubuntu it worked for me.
