" rel="nofollow - Hi,

I have a z370 Taichi with a 8700K + A 1070Ti discrete card.

It is a Linux mono-boot, with a windows 10 with gpu pass-through.

The problem is, if I connect a hdmi cable to the discrete gpu at the start of the computer, it will start (screen gets out of sleep) and the OS will try to work with the discrete card (already blacklisted the driver in the linux OS so that lead into a graphical interface crash) + the onboard one

Could it be possible to "deactivate the initialization" of the discrete GPU? (basically, starting only on onboard iGPU) so I don't need to unplug the hdmi cable at each (re)start? I searched and modified some chipset setting in the BIOS but I didn't succeed.
