I've reported the bug upstream as you've suggested. Here's the link: https://bugzilla.gnome.org/show_bug.cgi?id=720370
Yes, this is similar to the bug ID you've provided, but I'm not sure if it's the same issue. I'm having the problem on my Desktop (All-in-one Desktop) machine and not a laptop. Furthermore, this issue was not present when the very same machine had Ubuntu 13.04 installed. All worked fine then. Only after upgrading to Ubuntu 13.10 has this issue arrisen. I upgraded using the ISO, and did a full re-format and re-encryption of the full disk. So this seems to be an Ubuntu 13.10 problem, and not an Ubuntu 13.04 problem, as the other bug states. ** Bug watch added: GNOME Bug Tracker #720370 https://bugzilla.gnome.org/show_bug.cgi?id=720370 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1252507 Title: gsd-backlight-helper fails to change backlight To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1252507/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
