 |

Hi I'm installing in a VboxMachine for a server LEMP and in the Virtual Box Wiki https://wiki.gentoo.org/wiki/VirtualBox says it has to be enable but in the kernel Menu there is not such option
| Code: | Device Drivers --->
Graphics support --->
<*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) --->
[ ] DRM DP AUX Interface
[ ] Insert extra checks and debug info into the DRM range managers
< > kselftests for DRM
[ ] Allow to specify an EDID data set instead of probing for it
[ ] Enable DisplayPort CEC-Tunneling-over-AUX HDMI support
I2C encoder or helper chips ---> |
and
| Code: | /usr/src/linux # cat .config | grep CONFIG_DRM_FBDEV_EMULATION
|
don't give anything what I should do ? 
this is another question, could I edit /usr/src/linux/.config as text? I think would be easier
Thank you all for your time  |

Please never do that and read: https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Manual_kernel_configuration#Never_edit_.config
You havent found it in .config because some other options are not enabled - as @jburns already told - but you will find it in "make menuconfig".
You can find this option with / in "make menuconfig". Pressing "z" shows all hidden Options (its a toogle; press again and it switches off). Always work with <Help> in "make menuconfig". |

denn0n,
The make *.config tools are not text editors.
They are dependency aware tools.
When an option is off. The things that depend on it cannot be selected. It's a design feature that they do not even appear.
When an option is turned on, all the other options it needs are also turned on. I've seen as many as nine things being forced.
Would you do that yourself with a test editor?
The usual advice to anyone who has used a text editor on a kernel .config file is to throw it away and start from a known good backup.
