I cannot provide you with a straight solution, but perhaps a workaround. Here are some thoughts. In my experience it often fails when you try to install Qubes with nvidia, especially modern cards, but old cards have their quirks too. It's especially bad without nvidia proprietary drivers, which have to be installed in Dom0 after the Qubes installation if you want them to work properly. To begin with, it's nice that you even managed to boot up Qubes with your nvidia cards. * Did you install nvidia in Dom0 before attempting to enable your second monitor btw? * Alternatively, did you try install Qubes while the second monitor was on? * Also SLI might indeed be a factor too, you might want to try disable it and see if it works. Assuming that you're new to Qubes, imho, it's well worth the trouble, Qubes is awesome. * Do you have on-board graphics? Like for example Intel integrated graphics in your CPU? Intel graphics is known to run quite well in Linux/Qubes. If you do have Intel integrated graphics (change to primary in bios, you don't need to remove the graphic cards) then this is the most likely approach that will work without much trouble. Also you hardly need anything more than Intel graphics, Qubes can't run games or similar yet anyway. You will have to switch screen cables or use a KVM to do so, if you choose to dual-boot with windows or another system. Assuming you still use your graphics card on your dual-boot systems. Also I find it odd that you have to re-install Qubes. I usually have the opposite problem, my screen settings never ever stick with me between reboots or screen reconnections, I believe the fault is in XFCE4, I have to make an automated script to make settings stick. Perhaps a similar solution would make it easier to test without having to re-isntall Qubes every time. If you find the file which saves the second monitor configuaration, at least you should be able to edit it without having to re-install every time you try something new. Does tty terminal work? (Ctrl+Alt+F2, Ctrl+Alt+F1, etc.)? Irregardless, too little information, it would be helpful if you provide more details, especially if someone more knowledgeable drops by. I'm just a regular user like you, after all. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
