I also see this issue and I notice that /sys/class/backlight/XXX/brightness is modified both by g-p-m and by the Fn-keys on my laptop so it doesn't appear to be a situation where one is out of sync with the other. A simple way to reproduce this bug:
1. Set battery mode in g-p-m so that backlight is less than 100% when on battery (lets say 25%), and set backlight to dim when idle. 2. Set laptop to run on battery power so backlight dims (in this example to 25%). 3. Use Fn keys to change backlight back to 100%. 4. Wait for idle timeout to kick in and dim backlight completely. 5. Move the mouse to wake up from idle. Backlight will be set to 25% or whatever was set in g-p-m, not the 100% it was set to before idle. So basically it seems like g-p-m refers to its configured backlight setting when resuming from idle instead of storing the current backlight setting before going idle so it can then restore to that value. -- Disyncronisation with current brightness settings and g-p-m https://bugs.launchpad.net/bugs/140018 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
