I am experiencing this same bug but have isolated to a specific set of criteria that is 100% reproducible. This may not be the case for others, and it may occur in other screen configuration scenarios/combinations. I just hope my input may help pinpoint the root cause:
TheTLDR: It doesn't work with VirtualBox in "Fullscreen" on second display. Details of my or my scenario: 1.) I'm running VirtualBox on a second display 2.) It only occurs when the VM is in "Fullscreen" 3.) It works fine if VM is minimized, windowed or in "Seamless" mode 4.) Right now, I have it working in "Seamless" mode, which nice (but "Seamless" can sometimes be a little flaky with the window not wanting to be visible - but that's Oracle's problem) Note: It is very cool now that I realized that I can also copy/paste clipboard images back and forth with my VM... Maybe it's been around for a little while, but it's new to me :) ** Attachment added: "Just a Visual of VirtualBox Display Modes" https://bugs.launchpad.net/ubuntu/+source/gnome-screenshot/+bug/1102484/+attachment/4493690/+files/VirtualBox_Screenshot.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-screenshot in Ubuntu. https://bugs.launchpad.net/bugs/1102484 Title: Selecting 0✕0 screenshot area produces "All possible methods failed" error message Status in Gnome Screenshot: Fix Released Status in gnome-screenshot package in Ubuntu: Fix Released Bug description: gnome-screenshot 3.6.0-0ubuntu1, Ubuntu 12.10 1.
