My Unity Launcher is currently stuck open. Short of logging out and back in, does anyone have ideas for getting it to auto-hide as usual?
It turns out that the Launcher is supposed to stay open on workspaces containing no windows. Two of my workspaces had maximised windows which Unity didn't seem to be noticing, and when I closed those and then re-opened them, the Launcher reverted to its correct auto-hide behaviour.
Perhaps one could also simply move the window to another workspace and back to get the Launcher unstuck--I did not think to try that.
None of the methods above like Super S/Super-W, drag drops, min/max/move windows worked for me.
Ubuntu Unity Plugin, and re-enabling it.
If you wish to have the launcher always autohide, you can use the Unity plugin in the CompizConfig Settings Manager. See this question for complete instructions.
I've had the same problems. SO annoying. It seems to happen when I select and drag in certain programs. So far in Menedely Desktop and QtiPlot. The trick I've found is to go to a web page select text then begin to drag and the sidebar will go back to auto-hide.
Yes, it's a bug. What i do is start the expo plugin using the shortcut key and the launcher hides after that.
timmay143's workaround helped me. The bug seems to be fixed now: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/769703. Fix not released for Natty yet.
I've had this issue for years. It looks like on Ubuntu v16.10, if I gesture on my trackpad with four fingers to the right, it opens the launcher permanently (disables autohide). If I gesture back left, it closes (reenables autohide). I don't see any other indication that I've changed workspaces.
None of the suggested solutions work for me (16.10) - not even going into autosettings and disabling then enabling autohide.
The ubuntu "start button" is highlighted like it has focus.
I could restart unity - but it's a pain when you have many docs open.
This is so annoying and I must admit that even though I like unity - the launcher is subpar - even if it wasn't buggy.
