Every three months for several years I spend a whole day trying to make the second video card work on my laptop. Some will say that it cannot work on laptops for several reasons, in particular because the consumer GPU does not support vitualization, because on a MUXed system (radeon 7570M) it is impossible to switch two video cards simultaneously on the same monitor, almost certainly will not even work on the external video output, because the ACPI call fails to load the firmware. I keep doing so many tests, I find out about dozens and dozens of sites, but I only make small steps forward. Now I can load Windows 7 without having the blue screen, I see the card in the device manager, but it seems to be off. (error code 43). I put all the options, even though they are probably useless.
rd.qubes.hide_pci=02:00.0 modprobe=xen-pciback.passthrough=1 xen-pciback.permissive xen-pciback.hide=(02:00.0) kernelopts - iommu=soft swiotlb=16384 gfx_passthru True (qvm-features ??) But I don't understand why: 1. The windows 7 VM with the attached video card loads only with less than 4GB of RAM (otherwise it is blue screen) 2. I don't find in any way the possibility to edit the virtual machine configuration XML. 2.1 under "/ var / lib / qubes / appvms / WIN-7-2 /" the configuration file no longer exists. 2.2 I found the way to export the XML with virsh dumpxml, but with the qvm-start command there is no longer the "--custom-config" option 2.3 I force editing the XML from virsh edit (VM) in VIM, but then resume the values entered in qvm-features. 2.4 I can't change the amount of vram? (qvm-feature video-vram?) 3. the Windows guest video drive (both cirrus and vga) there is no monitor resolution (1366x768) Valid and working alternatives: spice? ovmf? dgpu on usb3? Dell precision 7000 series? I need windows only because there isn't a valid alternative to photoshop and other Adobe products, I don't find myself with gimp and krita. thanks bye -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
