Hi everyone,
I’m using Manjaro I3 x64 with an Intel i7 4790K processor which has an integrated Intel HD graphics card, as well as an NVIDIA GeForce RTX 2080 graphics card. I’ve managed to do GPU passthrough on KVM with the same configuration in the past, but I’m having problems now.
My goal is to boot my system and LightDM with the integrated Intel graphics card (iGPU) so I can reserve the GeForce RTX 2080 for my virtual machines. I’ve already blacklisted the NVIDIA driver at system startup by adding these lines to /etc/modprobe.d/mhwd-gpu.conf :
blacklist nouveau
blacklist ttm
blacklist drm_kms_helper
blacklist drm
blacklist nvidia
In addition, in my /etc/X11/mhwd.d/nvidia.conf file, I have configured the driver as follows:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 535.104.05
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0"
InputDevice "Keyboard0" "CoreKeyboard"

Section "Extensions"

EndSection
Section "InputClass"
Identifier "Keyboard Defaults"

Option "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection
Despite these manipulations, I’m having problems setting up the GPU passthrough. If anyone has encountered a similar problem or has any advice, I’d be grateful for any help you could provide.
