I have to admit that I'm fairly new to this OS, but it seems to me you don't really want a screen capture program to work out of one of the vms. That would break the compartmentalization badly, I think. As you note, it works in dom0 (as it does with me), and that's where it should work. I'm more used to VirtualBox than Xen, so the way I get my head around Qubes is to think of it simply as a very highly granular Virtualbox setup. In VirtualBox, if you open up a Windows desktop and use the screenshot program in that, you *only* expect it to work *on that desktop.* You can't open a screenshot program in the Windows desktop and get a shot of the Fedora desktop. The same thing would be true here, except the vms don't have desktops -- only windows. So... there's no desktop to take a screenshot of, except for dom0. It seems to me that if my fedora vm could take a shot of the entire screen, then the whole compartmentalization thing would be shot to hell. I may be wrong -- I'm not an expert here -- but I simply wouldn't expect it to work. There's this ironclad rule in life that usability and security are inversely related. You can mitigate it a little, or make it worse. The TSA for instance (for those of you outside the US, the TSA is our airport security service) maximizes inconvenience for a minimal to moderate increase in security. Qubes attempts to minimize inconvenience for a maximal increase in security. But the relationship still exists. Security is *always* inconvenient. billo -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
