I'm experiencing the same. Acer Aspire S7 392. Worked under 17.04, not under 17.10.
The only way I can change my screen brightness currently is via the command line: sudo tee /sys/class/backlight/intel_backlight/brightness <<< 200 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1727310 Title: Screen brightness slider isn't working on Acer Aspire v5 571g Status in gnome-shell package in Ubuntu: New Bug description: changing the screen brightness does not work when you try to change the slider on the toolbar at the top right ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: gnome-shell 3.26.1-0ubuntu4 ProcVersionSignature: Ubuntu 4.10.0-33.37-generic 4.10.17 Uname: Linux 4.10.0-33-generic x86_64 NonfreeKernelModules: zfs zunicode zavl zcommon znvpair ApportVersion: 2.20.7-0ubuntu3 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Wed Oct 25 17:10:04 2017 DisplayManager: lightdm GsettingsChanges: b'org.gnome.desktop.interface' b'gtk-im-module' b"'gtk-im-context-simple'" InstallationDate: Installed on 2015-08-27 (789 days ago) InstallationMedia: Ubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) SourcePackage: gnome-shell UpgradeStatus: Upgraded to artful on 2017-10-25 (0 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1727310/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
