In Qubes 4 I never had to enable it btw, oddly, it just works. I've solved the problem since posting, I was looking the entirely wrong place all along, but new ideas for clues came along after I had posted. So I deleted the topic since it had no views/posts at the time anyway and was resolved. But it seems it wasn't deleted after all x) But thinking it over again, perhaps this can help others looking to solve this too. I've found two methods to solve it, although the second is only half solved. It was a bit like treasure hunting, here's the results. 1'st approach: wmctrl -r :ACTIVE: -b toggle,fullscreen If this is written in dom0 terminal, or any AppVM terminal, then the window will go fullscreen. This is the one one may want if keybinding, and pressing an active keybind while another window of choice is active. Write a .sh script file in dom0, and save the command. Then it's just a matter of using dom0 keybinding to activate it. Which gives much more flexibility to alt+space+f, for example changing it to alt+f or numpad at the other side of the room for remote pre-configured controls, i.e. using Qubes as a large screen on a distance. It has many uses, just use ones own imagination to find one. Also I believe this is the command Qubes uses internally when pressing alt+space+f, but I did not manage to confirm that. Also another variant is to use; wmctrl -r :SELECT: -b toggle,fullscreen This variant essentially turns ones mouse into a click to fullscreen whichever window one may pick with the mouse. One can still keyboard alt+tab between windows, without loosing the pointer to click, if the window is buried under the other windows. But for keybinding purposes, the ACTIVE variant is better suited than SELECT, at least for my own needs. 2'nd approach: This is only half solving the problem, but simply writing in dom0, 'xdotool key alt+space' will bring up the XFWM4 popup menu, though I did not find a way to "chain it" to then select the last key, "f". But since I had the above solution already, I did not venture deeper to solve it, it needs the last step if anyone wants to use this approach. I'm personally content with the 1st approach though, it solves everything for my own needs. On the security side of things, then dom0 controlled fullscreen "should" be fine, for as long it stays in the control of dom0, and not the VM. If the VM can change the fullscreen, it's my understanding it can exploit the user in social hacking. But if you control which VM has access to fullscreen, then you can also limit this issue, and are less likely to fall victim. That's my understanding, it may be I misunderstood the attack vector, but I think its correctly understood. The reason full-screen is bad, as I've understood it, is that social hacking can happen when you least expect it, so if you manually enter fullscreen, for a VM with limited and locked-down purposes, i.e. heavily firewalled with one of few purposes to the internet, then you're much less likely to fall victim to screen social hacks. Do feel free to correct me if I'm wrong about that, though, I don't think the security is any different than using alt+space+f, since it's essentially the same thing, and also controlled from dom0. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
