Hi, I noticed this issue from bug 959106, thank Alex Wolfson. We know this issue and this is not only a issue in userpsace but in kernel, so it's not easy to fix it soon. We need the code ready in userspace(such as gnome-settings-daemon in gnome) and then we will fix the code in kernel. But the maintainer of the gnome-settings-daemon didn't accept the patch yet, see bug 959106
Anyway, there is an workaround to fix this, just do echo 1 | sudo tee /sys/module/video/parameters/brightness_switch_enabled -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/257827 Title: brightness changes twice when using hotkeys To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-power/+bug/257827/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
