dmesg from kernel 4.11.0-rc3 with drm-intel-next-2017-03-20
The screen is going black after switching to inteldrmfb. I`ve tested kernel
4.11.0-rc3 and 4.11.0-rc3 with drm-intel-next-2017-03-20, result is same. With
kernel from Linuxium there is still black screen, but I can control brightness
blindly (there is folder '/sys/class/backlight/intel_backlight', when in
4.11.0-rc3 in folder /sys/class/backlight there are 8 folders from acpi_video0
to acpi_video7). Kernel 4.8.x which goes with Ubuntu 16.10 is working fine, but
there isn`t brightness control. I`ve also tested latest Arch linux with Gnome
DE on wayland, same issue (Black screen even on TTY`s, without loading DE).
Architecture: x86_64
Kernel: 4.11.0-041100rc3-generic
Linux distribution: Ubuntu 16.10
Machine or mother board model: Toshiba Satellite Click 10 (LX0W-C64 model),
Cherry trail cpu, X5-Z8300
Dispay connector: DSI-1, as Xrandr says.
