@Stephen, Many thanks for your reply. Sorry my description maybe a bit mis-leading, this is not a single-touch bug, but a possible Unity bug that touchpad cannot reveal launcher if a left-click event happens via touch-screen.
Some more information for your reference: 1. This does not happen under Unity2D but only Unity3D 2. Windows hotkey still works, so the launcher can be called via hotkey 3. When issue occurs, unity --replace or compiz --replace cannot recover it. I only found restart lightdm (restart X) can recover the issue 4. No error occurs from $export UNITY_LOG_SEVERITY="=DEBUG;nux=DEBUG" $unity --replace 5. If I touch the screen before setting launcher to auso-hide mode, touchpad or external mouse still cannot reveal the launcher after autohide is selected. Extra information which may not relate to this issue directly: The position of touchpad pointer and touch screen pointer do not sync with each other. For example, if I move the pointer to place A via touchpad, then touch place B on the screen, then tried to move pointer via touchpad, the pointer appears at place A instead of place B. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.
