HP DV6 same problem. I do not think the bug is due to gnome-screenshot but it a problem of the keyboard map. STAMP is not recognized at all. First I noticed I was not able to use altgr+STAMP REISUB anymore, now the screenshot.
I have changed the shortcut for the screenshot to alt+h for instance and it works fine. If I open system settings->keyboard and then I click on the small keyboard icon I notice that the stamp button is not highlighted when I press it. The keyboard and Sysrq ware working fine on Ubuntu 13.04 for sure -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1295994 Title: Unable to use Printscreen Button on Ubuntu 14.04 in GNOME Shell To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screenshot/+bug/1295994/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
