Hi, Thanks for the bug-report, can you please run the following 2 commands in a shell: ls /sys/class/backlight As well as: for i in /sys/class/dmi/id/*; do echo $i; cat $i 2> /dev/null; done And copy and paste the output of both into your next comment here in bugzilla ? Thanks, Hans I see you've already done the /sys/class/backlight bit, so feel free to skip that :) You can already find the contents of the files in /sys/class/dmi/id in the attachment of my first comment. Or is there something missing? *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs. Fedora 20 has now been rebased to 3.17.2-200.fc20. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 21, and are still experiencing this issue, please change the version to Fedora 21. If you experience different issues, please open a new bug report for those. This is still happening with Fedora 21. *********** MASS BUG UPDATE ************** We apologize for the inconvenience.

Created attachment 930164 [details] /sys/class/dmi/id Description of problem: My ASRock B75M-ITX desktop board (CPU: G1610) shows a non-functioning backlight control (acpi_video0) in /sys/class/backlight. Booting the system with video.use_native_backlight=1 does not fix the problem (acpi_video0 still shows up) but using acpi_backlight=vendor fixes it. Version-Release number of selected component (if applicable): kernel.x86_64 3.16.1-300.fc20 kernel-core.x86_64 3.16.1-300.fc20 kernel-headers.x86_64 3.16.1-300.fc20 kernel-modules.x86_64 3.16.1-300.fc20 kernel-modules-extra.x86_64 3.16.1-300.fc20 Steps to Reproduce: 1. Boot system and log in to GNOME. 2. Check system menu and/or /sys/class/backlight.
