[Bug 1348020] Re: [Dell Latitude 3540] Unable to control brightness
I am using Dell Latitude 3540 and Ubuntu 14.10. Brightness works just fine (with hotkeys and in settings). However, the brightness level is not saved when restaring computer so next time computer starts the brightness level is at 100%. Should I report this as a new bug? I managed to control this by changing /etc/rc.local with command echo 600 /sys/class/backlight/intel_backlight/brightness -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1348020 Title: [Dell Latitude 3540] Unable to control brightness To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1348020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yes, if a system has never been certified before, it's acceptable to test it again in 14.04.2, thanks! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1348020 Title: [Dell Latitude 3540] Unable to control brightness To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1348020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Upstream will use video.use_native_backlight=1 as default in 3.16, so I expect this bug will be fixed in Ubuntu soon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1348020 Title: [Dell Latitude 3540] Unable to control brightness To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1348020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello Anthony, Does it means that for this kind of bug, they won't be fix in Trusty 14.04.
