Similiar issue is on x86, but the launcher reveals sometimes when you try to move the mouse after the left edge of the screen. The behaviour seems to be inentional (except it shoud work always), related to this "feature":
http://design.canonical.com/2012/01/launcher-reveal-prototype/ The feature was introduced in the unity-2d 5.7 version as https://launchpad.net/bugs/765819. Experimenting with dconf-editor shows that setting com.canonical.Unity2d.Launcher edge-reveal-presure to 0 makes the auto hide behavoiur to work more or less similiar as before. Introducing the new reveal behavoiur without easy way to achieve the old behavoiur makes realy bad experience from users point of view. It looks like something which worked good before is broken after upgrade. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/989477 Title: Unity launcher does not re-appear when autohide switched on To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-2d/+bug/989477/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
