thank you for the reply. i have had contact with nvidia.my laptop screen is attached to the nvidia card and there is no way for me to use the intel iGPU with the proprietary NVIDIA
card driver. to make this work i have to have nouveau with reverse prime.

Hi there,
this works already, see: https://bugs.gentoo.org/show_bug.cgi?id=692206

intel, nvidia and libglvnd is what is needed. The only required configuration change is:

Code: Select all

    Section "ServerLayout"
      Identifier "layout"
      Option "AllowNVIDIAGPUScreens"
    EndSection

as described in: https://download.nvidia.com/XFree86/Lin ... fload.html

However, my next problem was, additional displayport/hdmi displays were only recognized by the dGPU and not presentable to the iGPU. So I had to switch my bios to discrete GPU, instead of the hybrid configuration. I am trying to figure out a way to preset additional displays to xrandr in the above configuration.

Hi,

dear Gentoo users, you have my deep gratitude, as thanks to this advice:

Here are my working configs where I select videocard via grub menu, some values are specific to thinkpad t470p (for example, bus id) but I hope these configs will be helpful in order to figure out which steps need to be performed to get proprietary drivers working with optimus card:

for openrc users: http://blog.jee.org.ua/linux/gentoo/nvi ... timus.html

and this one

intel, nvidia and libglvnd is what is needed. The only required configuration change is:

Code: Select all

    Section "ServerLayout"
      Identifier "layout"
      Option "AllowNVIDIAGPUScreens"
    EndSection

I was finally able to make Nvidia / intel to run properly on my local machine and use 3D acceleration to its fullest.

The most useful piece of advice for me was to include XRandR instruction in script loaded by the desktop environment, e.g. sddm ( /usr/share/sddm/scripts/Xsetup ) for me. I tried to include these commands in /etc/X11/xinit/xinitrc but it wouldn't work (now I know why).

Best regards.
