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.

Additional Info: I have tested the screenshot tool in an unchanged Fedora 26 template, no content is shown after screenshoting. Instead of my first post, the screenshot is only shown as a white (not black) area. The screenshot tool is working in dom0. I have run lspci in dom0: 00:02:0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06) 01:00.0 VGA compatible controller: NVIDIA Corporation GK106GLM [Quadro K2100M] (rev all) [799] Original-Nachricht An 16.

Yes something like that, collaborative troubleshooting is always better. Seriously of course I want to get screenshots working asap but I also don't want to see that a newbie users, tries Qubes run into the same problem and thinks "boo, the Linux moment again - nothing works".

The lenovo W530 has two GPUs: 1) Intel HD 4000 2) nVidia Quadro K2000M Are you interested in lspci of the AppVM or in dom0? Screenshots in dom0 are working btw.

Because you are the first one since release of qubes 4.0 rc4 (first handy information), you should provide some more information than telling us the standard template everyone else using qubes 4.0 rc4 also have. In example what video device does lspci list? What processor are you using? Any modifications in grub config files? Ask yourself some questions what may be of interest. Have you started your template one more time to (maybe) finish some system tasks? Have you tried turning it off and on again? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
