Screen brightness also seems to be an issue. Using the the brightness control (System Settings > Brightness and Lock) I am able to control screen brightness from 0 to 9442905. At minimum brightness, the backlight is turned off completely, but the screen itself remains on, and can be observed by shining a bright flashlight on the screen.
The value of /sys/class/backlight/intel_backlight/actual_brightness varies as follows #Maximum brightness $cat /sys/class/backlight/intel_backlight/actual_brightness 9442905 #Minimum brightness $ cat /sys/class/backlight/intel_backlight/actual_brightness 0 The Brightness Control slider (in Brightness and Lock) modifies the '/sys/class/backlight/intel_backlight/actual_brightness' in by 94429 for 100 steps in total. Additionally no matter the value of brightness set, unplugging the AC adapter 'sets' the screen brightness to 4517782. Plugging the AC adapter back in 'sets' the screen brightness to 3851224. Previously set values are ignored. Screen is dimmer when connected to AC adapter than when on battery (3851224<4517782) Please advise if i should file a new bug -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1063804 Title: fn keys for brightness on HP Compaq 6710b not working [regression][12.10] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1063804/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
