In the meantime, it also happened while I was not running dasher; so it probably is not dasher's fault. Thus, I removed dasher from the "affected package" field.
Moreover, the problem also happened once in GNOME 3. But, I never saw it in Unity 2D, though I have been using unity 2D quite a lot these last days to avoid the problem. ** Tags removed: a11y -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/898761 Title: Display falls into sleep after a bit of use in Unity but not in Unity 2D To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/898761/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
