I had this problem as well. However, when I went into Preferences in CCSM and reset all settings back to default, PrtSc worked again. I then went through and individually changed each Compiz plugin settings back to the way I wanted them, which includes the Desktop Cube, and PrtSc still works.
I haven't tried rebooting yet to make sure everything still works afterward, but based on what I experienced here, it seems maybe older Compiz profiles saved on Intrepid and before might be the cause of the problem. -- Ubuntu 9.04 - PrintScreen Key does not start gnome-screenshot https://bugs.launchpad.net/bugs/366784 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
