Nvidia Prime 450 second monitor is black

Hello,

Do any of this comments help?

Black output on Monitor, Hybrid AMD/Nvidia Laptop with HDMI on dGpu under Nvidia 450 driver

So it was working sort of in that I had some sort of script that I’d installed (optimus switching if I recall) that let me switch between the two GPU’s that are in this machine, so if I wanted to use the monitor, if I swtiched to the Nvidia GPU (and rebooted) then I could use the monitor, and then when I wanted to use the laptop by itself (and didn’t need the Nvidia) I could switch back to the AMD GPU (and reboot) it would work power-saving. Edit: Think it was this GitHub - dglt1/optimus-switch…

No HDMI output on AMD/NVIDIA hybrid laptop

Resolved! Somehow HDMI started working with the default Manjaro video-hybrid-amd-nvidia-450xx-prime drivers. No need for optimus-switching. I suspect that rebooting with the monitor already plugged in did the trick.

Problems with AMD CPU integrated graphics and nvidia GPU

then you should add sudo mhwd -i pci video-hybrid-amd-nvidia-450xx-prime and reboot glxinfo | grep 'renderer string' prime-run glxinfo | grep 'renderer string' # Nvidia render-offload alias alias nvr="__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia" alias vkr="__NV_PRIME_RENDER_OFFLOAD=1" after you close/open terminal the alias for both will be set and then it’s #opengl nvr glxgears #vulkan vkr vkcube
