i dont get what these infos would be good for, sorry.
It doesnt matter in which slot you put the GPU, i have acutally 3 installed.
type nvidia and amd. but as i cant passthrough the nvidia properly (know nvidia incompatibilities) and changed to 3 amd GPUs.
also using the GPU inside my vm was not the problem this thread was opened for.
my question was how to use the internal GPU (vga output) for the server itself even if a GPU is installed.
here i was told, not possible. as soon as i plug in another GPU the internal one (vga output) would be disabled.
this is just wrong. i only forgot to activate the bios rom option for the PCIe Slot for the GPUs in the Server-Bios. After activating, i could use all my GPUs independet from the server and the server still used the onbaord VGA as uotput device.
Nothing to do with Slots, GPUs itself, brands, types or even VMs
Hope this will help someone lateron, took me quite some days to get it sorted LOL
See you and thanks!
