Thanks to everyone for your help, I've switched to RedHat's Fedora where everything is working ;)
Cheers, 04.09.2018, 22:46, streampp <strea...@rambler.ru>Hi everyone! I'd like to ask for a little help here. I'm fighting with Macbook Air 6,1 (late 2013) for a week now, and I'm kind of stuck. Everything is working (wifi, camera, suspend/resume) but keyboard backlight. Actually, it works when I'm writing 0-255 to /sys/devices/platform/applesmc.768/leds/smc::kbd_backlight/brightness, but... I can't change keyboard's brightness with F5-F6 keys. I can change screen's brightness with F1-F2, I can change volume with F11-F12, but F5 and F6 just don't work and don't change keyboard's brigthness. All I can see on a screen when I'm pressing F5-F6 is an icon of keyboard's backlight, but it won't change.I saw a lot of recipes on internet about writing scripts with "echo > /sys/devices/.../smc::kbd_backlight/brightness", but it turned out, that other distributions (Fedora, Ubuntu, OpenSUSE) works without those scripts "out of the box".Could anyone please tell me where to start looking? I have no idea which piece of software handles Fn-keys? Is it udev, systemd, xorg? Why Fedora, Ubuntu and OpenSUSE work? I kind of think that I'm missing one single string somewhere in some config, but I don't know where... Thank in advance, I use: - Debian buster/sid with latest updates - Gnome 3 desktop install (tried with xorg and with wayland) - linux-image-4.17.0-3-amd64-4.17.17-1- lspci: 00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09) 00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 09) 00:14.0 USB controller: Intel Corporation 8 Series USB xHCI HC (rev 04) 00:15.0 DMA controller: Intel Corporation 8 Series Low Power Sub-System DMA (rev 04) 00:15.4 Serial bus controller [0c80]: Intel Corporation 8 Series SPI Controller #1 (rev 04) 00:16.0 Communication controller: Intel Corporation 8 Series HECI #0 (rev 04) 00:1b.0 Audio device: Intel Corporation 8 Series HD Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 1 (rev e4) 00:1c.1 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 2 (rev e4) 00:1c.2 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 3 (rev e4) 00:1c.4 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 5 (rev e4) 00:1c.5 PCI bridge: Intel Corporation 8 Series PCI Express Root Port 6 (rev e4) 00:1f.0 ISA bridge: Intel Corporation 8 Series LPC Controller (rev 04) 00:1f.3 SMBus: Intel Corporation 8 Series SMBus Controller (rev 04) 02:00.0 Multimedia controller: Broadcom Limited 720p FaceTime HD Camera 03:00.0 Network controller: Broadcom Limited BCM4360 802.11ac Wireless Network Adapter (rev 03) 04:00.0 SATA controller: Marvell Technology Group Ltd. 88SS9183 PCIe SSD Controller (rev 14) 05:00.0 PCI bridge: Intel Corporation DSL3510 Thunderbolt Controller [Cactus Ridge 4C 2012] (rev 03) 06:00.0 PCI bridge: Intel Corporation DSL3510 Thunderbolt Controller [Cactus Ridge 4C 2012] (rev 03) 06:03.0 PCI bridge: Intel Corporation DSL3510 Thunderbolt Controller [Cactus Ridge 4C 2012] (rev 03) 06:04.0 PCI bridge: Intel Corporation DSL3510 Thunderbolt Controller [Cactus Ridge 4C 2012] (rev 03) 06:05.0 PCI bridge: Intel Corporation DSL3510 Thunderbolt Controller [Cactus Ridge 4C 2012] (rev 03) 06:06.0 PCI bridge: Intel Corporation DSL3510 Thunderbolt Controller [Cactus Ridge 4C 2012] (rev 03) 07:00.0 System peripheral: Intel Corporation DSL3510 Thunderbolt Controller [Cactus Ridge 4C 2012] (rev 03) - lsmod |grep apple hid_apple 16384 0 applesmc 24576 0 input_polldev 16384 1 applesmc apple_bl 16384 0 - xinput: cat /tmp/111 ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ xwayland-pointer:15 id=6 [slave pointer (2)] ⎜ ↳ xwayland-relative-pointer:15 id=7 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ xwayland-keyboard:15 id=8 [slave keyboard (3)] - ls -1 /sys/class/leds/ input10::capslock input10::compose input10::kana input10::numlock input10::scrolllock smc::kbd_backlight
