This test was done on 3.9.0-030900rc1-generic if it matters any value from 0 (completely off) to 4882 (100%) works for this, increments of 2 have a effect echo 100 | sudo tee /sys/class/backlight/intel_backlight/brightness it is like god mode for the back light level
the lowest the fn+brightness keys allow is a level of 1000 in /sys/class/backlight/intel_backlight/brightness neither /sys/class/backlight/intel_backlight/brightness nor /sys/class/backlight/acpi_backlight/brightness change when using the brightness keys i think if the system could query the backlight without altering it, it would return to its working state like in 3.6.11 would be nice if the fn keys would synchronize with what the software sets the backlight to (never worked even on the old bios) as long as software like xbacklight and the xfce4-brightness-plugin can function properly that is good enough for me -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1138168 Title: Backlight control regression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1138168/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
