I ran gnome-control-center from terminal and activated screen-cc-panel (I am running desktop system without battery) Got this warining:
(gnome-control-center:5897): screen-cc-panel-WARNING **: Error getting brightness: GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._gsd_5fpower_5fmanager_5ferror.Code0: gsd-backlight-helper failed: No backlights were found on your system >From http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/oneiric/gnome- control-center/oneiric/view/head:/panels/screen/cc-screen-panel.c, it seems like set_brightness_cb (GObject *source_object, GAsyncResult *res, gpointer user_data) is called. Is it necessary to call this method on a system with only ac-power? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/863038 Title: If turnoff the screen setting set to 'never' screen turns off instantly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/863038/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
