Hi,

I run Fedora 26 maybe since Alpha release on my Zenbook and in between Alpha and Beta I lost backlight control from gnome shell and /sys/class/backlight/intel_backlight/brightness.
Then after 4.11.3 kernel I wasn't able to boot anymore, I discovered that switching to CSM mode solved the problem it also restored the backlight control from /sys/class/backlight/intel_backlight/brightness but still not from gnome shell.
Updating BIOS didn't help.
Does anyone got similar troubles?
Did you solve them?

Best regards,
Alexis.
