Screen brightness control disappeared
Hi, I've got a problem after update from kernel-4.15.16-300.fc27.x8664 to kernel-4.15.17-300.fc27.x8664 and in the newest version released by Fedora through dnf: kernel-4.16.3-200.fc27.x86_64 it happens also. If I boot to 4.15.16 again problem no exists.
It's laptop with Fedora 27, Gnome, Intel Core i7 3540M with Intel Graphics and nVidia 640M on the board.
After an update to the new kernel I cannot control brightness of the screen (keyboard shortcuts doesn't work for brightness only; I cannot see controls in gnome environment), and gnome control panel shows inaccurate settings for this screen (for example I can choose frequency of 120Hz in 60Hz laptop's screen). No other screen is connected now.
In gnome logs I can see an error with nouveau: nouveau 0000:01:00.0: devinit: 0x00006331[0]: script needs connector type kernel device: +pci:0000:01:00.0 priority: 6
Can You please tell me what's wrong? I changed nothing, only update via DNF.
