What about kms and fbdev (see https://wiki.gentoo.org/wiki/Intel#Kernel)?

Code:

$ grep -i i915 .config
CONFIG_DRM_I915=y
CONFIG_DRM_I915_KMS=y
CONFIG_DRM_I915_FBDEV=y
# CONFIG_DRM_I915_PRELIMINARY_HW_SUPPORT is not set
CONFIG_SND_HDA_I915=y

Kernel here is linux-4.1.15-gentoo-r1.

Hello charles17

Kernel in use 4.5.0

Code:

zcat /proc/config.gz | grep -i fbdev
CONFIG_DRM_FBDEV_EMULATION=y

Add more data, when boot after splash gentoo screen, the video card turn off and the log screen not is shown any more and the TV panel shows "no signal".

I do assume you logged in into the ssh session with

Code:

ssh -Y

or at least

Code:

ssh -X

so that the DISPLAY variable is set ?

Have you set the driver and reemerged using video_cards?
