Unity launcher bar stuck and won't hide

Solution 1:

Run this in a Terminal (Ctrl+Alt+T):

unity --replace

That works for me on Ubuntu 12.04.

Solution 2:

Drag a desktop icon a bit.

Helps against the stuck launcher bar with Opera on a 32-bit system. Another solution would be to set the launcher not to hide in the first place (that's my solution for now). See How can I configure Unity's launcher auto-hide behavior?

There are also bug reports:

• Opera: bug 741731 (note the "Won't Fix" as it's a bug in Opera)
• Another one - not sure what's the actual status on this one.

Solution 3:

I ran into the same issue on 14.04. It seems this can happen with the four-finger slide gesture. If this is the case, simply do a four-finger slide to the left to slide the bar back into place.

Solution 4:

Its not uncommon for the launcher to get stuck. Opening the dash with the Super Key seems to fix it for me and its way better than killing a program.

If you can reproduce it, you might want to post a bug report.

Solution 5:

Same problem when using Netbeans (Java) : when I drag tabs to reorganize them, the launcher appears and gets stuck (ie wont hide anymore). Could not fix the problem, but found 2 solutions : - drag and drop Firefox tabs around - drag something to the laucher
