More info regarding Toshiba Satellite R830: I can't change brightness after returning from sleep with Fn-keys, but echoing numbers to /sys/class/backlight/intel_backlight/brightness does change the brightness properly.
It seems that Fn keys write to /sys/class/backlight/acpi_video0/brightness, which doesn't do anything. Perhaps a fix could be made in Unity (or gnome power manager) to prefer intel_brightness if it's available? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/568611 Title: Screen brightness control fails on Dell Studio 1558 To manage notifications about this bug go to: https://bugs.launchpad.net/null/+bug/568611/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
