*I have 3 GPUs in my PC. Actually the BIOS uses the geforce 1060 to start it. So,two GPUs are out and kept free. The Geforce RTX 2080 ti and the Intel CoffeeLake-S GT2 [UHD Graphics 630]. I'm able to pass through the RTX 2080 ti to a linux vm,but I'm not able to do the same with the UHD Graphics 630. As I have explained in the post,there is nothing that keeps it busy. I'm not using it. Both my monitors are connected to the 1060 using the twinview mode. One is using the DisplayPort,the other one is using the HDMI port. When I want to pass the RTX 2080 inside a Linux VM and I need to use my 2 monitor,I detach the HDMI cable from the 1060 and I attach it to the RTX 2080 ti and it's done. I can use it inside my bhyve VM. If I don't want to use bhyve,I connect the HDMI cable to the 1060 and in this case I can use two screens at the same time without running a VM. Cool. I can do this only with the RTX 2080 ti,but not with the Intel GPU. If I'm obliged to use it even if I don't use it,I can't imagine how and in which kind of situation I can pass it through.* Il giorno ven 29 lug 2022 alle ore 16:20 Mario Marietto < marietto2008@gmail.com> ha scritto: > Maybe I forget to setup something correctly,but : > > 1) I've removed the xf86-video-intel driver from the system with : pkg > remove xf86-video-intel > > 2) i haven't any i915kms or legacy intel module inside the memory : > > # kldstat | grep i915 : nothing > # kldstat | grep kms : nothing > # kldstat | grep intel : nothing > > 3) this is my xorg.conf (where is there is no trace of intel driver) > > Section "ServerLayout" > Identifier "X.org Configured" > Screen 0 "Screen0" LeftOf "Screen1" > Screen 1 "Screen1" > InputDevice "Mouse0" "CorePointer" > InputDevice "Keyboard0" "CoreKeyboard" > EndSection > > Section "Files" > ModulePath "/usr/local/lib/xorg/modules" > FontPath "/usr/local/share/fonts/misc/" > FontPath "/usr/local/share/fonts/TTF/" > FontPath "/usr/local/share/fonts/OTF/" > FontPath "/usr/local/share/fonts/Type1/" > FontPath "/usr/local/share/fonts/100dpi/" > FontPath "/usr/local/share/fonts/75dpi/" > FontPath "catalogue:/usr/local/etc/X11/fontpath.d" > EndSection > > Section "Module" > Load "glx" > EndSection > > Section "InputDevice" > Identifier "Keyboard0" > Driver "kbd" > EndSection > > Section "InputDevice" > Identifier "Mouse0" > Driver "mouse" > Option "Protocol" "auto" > Option "Device" "/dev/sysmouse" > Option "ZAxisMapping" "4 5 6 7" > EndSection > > Section "Monitor" > Identifier "Monitor0" > VendorName "Monitor Vendor" > ModelName "Monitor Model" > EndSection > > Section "Monitor" > Identifier "Monitor1" > VendorName "Monitor Vendor" > ModelName "Monitor Model" > EndSection > > Section "Device" > Identifier "Card0" > Driver "nvidia" > BusID "PCI:1:0:0" > EndSection > > Section "Screen" > Identifier "Screen0" > Device "Card0" > Monitor "Monitor0" > SubSection "Display" > Viewport 0 0 > Depth 1 > EndSubSection > SubSection "Display" > Viewport 0 0 > Depth 4 > EndSubSection > SubSection "Display" > Viewport 0 0 > Depth 8 > EndSubSection > SubSection "Display" > Viewport 0 0 > Depth 15 > EndSubSection > SubSection "Display" > Viewport 0 0 > Depth 16 > EndSubSection > SubSection "Display" > Viewport 0 0 > Depth 24 > EndSubSection > EndSection > > Section "Screen" > Identifier "Screen1" > Device "Card0" > Monitor "Monitor1" > SubSection "Display" > Viewport 0 0 > Depth 1 > EndSubSection > SubSection "Display" > Viewport 0 0 > Depth 4 > EndSubSection > SubSection "Display" > Viewport 0 0 > Depth 8 > EndSubSection > SubSection "Display" > Viewport 0 0 > Depth 15 > EndSubSection > SubSection "Display" > Viewport 0 0 > Depth 16 > EndSubSection > SubSection "Display" > Viewport 0 0 > Depth 24 > EndSubSection > EndSection > > What could be wrong at this point ? > > Il giorno ven 29 lug 2022 alle ore 15:42 Mario Marietto < > marietto2008@gmail.com> ha scritto: > >> It's not used by the host.
