I don't know how the KbdBackLight interface is meant to work. It seems to be defined in package 'upower'. And that error seems to be from code in unity-settings-daemon where it fails to change the keyboard backlight brightness, because something isn't implementing "SetBrightness". And even then, the error only seems to occur when unity-settings-daemon changes to GSD_POWER_IDLE_MODE_BLANK. So I wouldn't expect that to be related to logging in, probably.
Do you have a keyboard backlight at all? Or an external keyboard plugged in? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730458 Title: Ubuntu (gnome) freezes temporarily upon login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1730458/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
