Hello, I am using 3.8.0.26 on Kubuntu 13.04 (KDE) Samsung Laptop and currently using "acpi_osi=Linux acpi_backlight=vendor" to enable backlight control. Whenever I log off, the controls are disabled again and I need to run intel_backlight. Another problem is power profiling. Whatever I set dimming and/or backlight off durations. It automatically turns it off in 5 minutes (even I totally disable it).
Do you have any idea why the problem is still not solved? -- 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/ubuntu/+source/alsa-driver/+bug/568611/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
