 |
|
I have a laptop with nvidia and intel video cards. I've just set up Xorg server and able to start it using startx. But when I try to check opengl it fails:
| Code: |
# glxinfo
name of display: :0.0
Error: couldn't find RGB GLX visual or fbconfig
|
My xorg.conf is empty, nvidia drivers are loaded, i915 driver is built into kernel (as DRI option).
| Code: |
# lsmod | grep -i nvidia
nvidia_drm 40960 0
nvidia_modeset 1060864 1 nvidia_drm
nvidia 13553664 25 nvidia_modeset
ipmi_msghandler 40960 1 nvidia
|
OpenGL configuration is references to nvidia:
| Code: |
# eselect opengl list
Available OpenGL implementations:
[1] nvidia *
[2] xorg-x11
# eselect opencl list
Available OpenCL implementations:
[1] nvidia *
|
Video cards option:
| Code: |
# cat /etc/portage/make.conf | grep VIDEO_CARDS
VIDEO_CARDS="nvidia i915 intel"
|
lshw output:
| Code: |
# lshw -c display

Can someone help me please to make nvidia working with intel via DRI and configure opengl?

Is DRM configure din the kernel? Check kernel configuration for CONFIG_DRM and post output.
I've not read too much about this card (is it a combo of nvidia+intel card) that does support hopefully support what you are trying to do.
But I don't know if Nvidia portion of the card is truly independent of the intel portion so I don't know about this, but eliminating the intel support in the kernel...would that possibly break the graphical system altogether? I don't know if that is the answer, but DRM and Nvidia drivers do conflict and could require rebuild of the drivers. |

Thanks. I've fixed it by installing https://wiki.gentoo.org/wiki/NVIDIA/Bumblebee and configuring i915 as a primary graphic card using Xorg-X11 libs as default OpenGL, now I can use Nvidia OpenGL implementation by running process with primusrun:
| Code: |
# glxinfo | grep -i "opengl version"
OpenGL version string: 3.0 Mesa 18.1.9
# primusrun glxinfo | grep -i "opengl version"
OpenGL version string: 4.6.0 NVIDIA 396.54
