You have:
| Code: | | # CONFIG_FB is not set |
With UEFI, Framebuffers are required to output anything to the screen. The machine is likely working just cannot display video.
Enable this and CONFIG_FB_EFI and CONFIG_FRAMEBUFFER_CONSOLE to even have a chance to display anything. |

skynoob,
There is more ...
See PC Boot Process
Particularly Console drivers and Configuring the kernel
CONFIG_FB is a menu.

skynoob,
Gentoo does not have problems, only "learning opportunities" :)
Start a new topic for your KDE issue.
