In recent kernels, I'm unable to set this option:

CONFIG_DRM_VBOXVIDEO

Isn't in the Gentoo kernel anymore?

If I try to add it manually in .config, it is automatically deleted when I save the new config using for example menuconfig.

Then, that option is needed to get 3D hardware support via DRM.

Any info?


Thank you.

[Moderator note: this post, and only this post, was originally attached to the long since solved topic [Solved]Virtualbox Gentoo, Start X No screens found and more. -Hu]

Do this CONFIG_DRM_VBOXVIDEO option on gentoo kernel is still available?

I can't find it and enable it in recent Gentoo kernels. And this option is mandatory to enable hardware 3D accelleration in virtualbox guest.

If I du explicity enable it with:

CONFIG_DRM_VBOXVIDEO=m

iin .config it is deleted becouse it seems it doesn't exist anymore.

Any info in how to get it back or in how to get 3D accelleration in Gentoo guest without it?

Have you satisfied the prerequisites shown in menuconfig? As of the current kernel (5.0-rc7), it states:
v5.0-rc7:drivers/staging/vboxvideo/Kconfig:
config DRM_VBOXVIDEO
    tristate "Virtual Box Graphics Card"
    depends on DRM && X86 && PCI

Which Gentoo kernel? When you have a question about a change over time, please specify the version you are using.

This is one of the reasons we always tell people not to edit .config by hand.
