 Posted: Fri Aug 10, 2018 5:20 am Post subject: [Solved] Kernel generated by genkernel fails to start xorg |
 |
|
I tried to follow Gentoo wiki to install the modesetting driver for my intel integrated video card and changed some of the kernel options. After rebooting, xorg fails to start. I used | Code: | | genkernel --lvm all |
to fix this, but failed. It seems that genkernel inherits configs from the current running kernel. How can I disable this feature and let genkernel generate a brand-new kernel based on only it's detections?
Here's the output of dmesg
If any of you guys know something please let me know 
Thank you in advance!

You can add --menuconfig option to genkernel and disable via menu the undesired config

Hi,
as fedeliallalinea said, add "--menuconfig" and check for the following:
| Code: |
[ 7.860218] [drm] The driver support for your hardware in this kernel version is alpha quality
See CONFIG_DRM_I915_ALPHA_SUPPORT or i915.alpha_support module parameter
to enable support in this kernel version, or check for kernel updates.
|
In addition check, if you have the correct firmware packages installed. Maybe the coffee lake cpu needs a special firmware to run kms properly.
greets, Stefan
