You have been subscribed to a public bug: After a recent update to Trusty, the print-screen button appears to be hard-wired to take a screenshot.
In the keyboard shortcuts setup "Take a screenshot" is disabled (was print key), "minimise window" is set to the print key. Up until about two days ago, this worked fine, now these settings are ignored and pressing the print key makes the screenshot sound (no popup screenshot dialog, though) and the window is unchanged. $ lsb_release -rd Description: Ubuntu Trusty Tahr (development branch) Release: 14.04 $ apt-cache policy ubuntu-system-settings ubuntu-system-settings: Installed: (none) Candidate: 0.1+14.04.20140218.1-0ubuntu1 Version table: 0.1+14.04.20140218.1-0ubuntu1 0 500 http://gb.archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages ** Affects: unity-control-center (Ubuntu) Importance: Low Status: Incomplete -- print screen button appears hard-wired to screenshot https://bugs.launchpad.net/bugs/1284532 You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-control-center in Ubuntu. -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
